Understanding Smart Air Conditioners in the Sub-$500 Range
What Makes an AC “Smart”?
Smart functionality extends far beyond a simple remote control app. At its core, a genuine smart air conditioner offers Wi-Fi connectivity that enables cloud-based control, automation, and integration with broader smart home ecosystems. Look for units that support 2.4GHz networks (most common in this price range) and provide real-time status updates. The difference between a “Wi-Fi enabled” unit and a truly smart one lies in its ability to learn your habits, respond to external triggers like weather changes, and operate autonomously based on rules you set. Budget models typically nail the basics—app control and voice commands—but may skimp on advanced features like machine learning or detailed energy analytics.
The Budget-Friendly Reality Check
The sub-$500 price point sits at an interesting intersection of capability and compromise. Manufacturers achieve this affordability by focusing smart features on software rather than hardware bells and whistles. You’ll get robust app control and scheduling, but premium materials, ultra-quiet compressors, and exotic designs stay out of reach. Expect plastic construction, standard efficiency ratings, and straightforward installation kits. The magic happens when companies prioritize firmware development over flashy hardware—this is where you find hidden gems that punch well above their weight class. Understanding this balance helps set realistic expectations while still demanding excellent value.
Decoding BTU Ratings for Your Space
Room Size Calculations
British Thermal Units (BTUs) measure cooling power, and getting this number right determines whether your smart AC becomes your favorite gadget or a disappointing paperweight. The standard formula—20 BTU per square foot—serves as a starting point, but budget units often list maximum coverage that assumes perfect conditions. For a 150-square-foot bedroom, a 6,000 BTU unit works theoretically, but factor in real-world inefficiencies. In the sub-$500 category, manufacturers rarely oversize their components, so err on the side of caution. A 6,500-7,000 BTU unit for that same room provides buffer capacity for those 95°F heatwaves without cycling too frequently.
Ceiling Height and Sunlight Factors
Your room’s personality dramatically impacts BTU requirements. High ceilings above 8 feet demand 10% more capacity per additional foot. That sunny south-facing room with floor-to-ceiling windows? Add another 10-15%. Kitchen installations require a full 4,000 BTU boost to combat heat-generating appliances. Budget smart ACs under $500 typically max out around 10,000-12,000 BTU, making them ideal for spaces under 450 square feet with standard ceilings. For attic apartments or sun-drenched living rooms, you might need to prioritize raw cooling power over smart features—or accept that the unit will run continuously during peak heat.
Energy Efficiency: Saving Money Beyond the Purchase Price
EER and CEER Ratings Explained
Energy Efficiency Ratio (EER) and Combined Energy Efficiency Ratio (CEER) reveal how many BTUs of cooling you get per watt of electricity. In the budget category, aim for a minimum EER of 11.0 or CEER of 10.5. Anything below these thresholds means your “budget” purchase will guzzle electricity, negating initial savings. The sub-$500 market has seen impressive efficiency gains recently, with many models hitting 12+ EER thanks to improved compressors and fan designs. This translates to roughly $30-50 annual savings compared to older units—effectively paying for the smart features through reduced utility bills.
Energy Star Certification Importance
That blue Energy Star logo isn’t just marketing fluff—it guarantees the unit meets strict EPA efficiency guidelines, typically placing it in the top 25% of its class. For budget smart ACs, Energy Star certification often indicates better insulation, more precise temperature sensors, and smarter defrost cycles. These units frequently include eco modes that automatically adjust cooling intensity based on room occupancy and outdoor temperature, features that cheaper non-certified models lack. The certification also suggests more rigorous quality control, reducing the risk of early failure.
Essential Smart Features to Prioritize
Wi-Fi Connectivity Standards
Dual-band Wi-Fi (2.4GHz and 5GHz) rarely appears under $500, so accept that 2.4GHz is your reality. This isn’t a dealbreaker—2.4GHz provides better range through walls anyway. What matters more is signal strength: look for units that explicitly mention “enhanced Wi-Fi range” or “external antenna.” Weak connectivity renders all smart features useless. Before purchasing, use a Wi-Fi analyzer app to check signal strength at your intended installation location. If you’re hovering around -70 dBm or weaker, consider a Wi-Fi extender or a unit known for robust connectivity.
Voice Assistant Ecosystems
Most budget smart ACs play nice with Alexa and Google Assistant, but the depth of integration varies wildly. Basic commands like “turn on the AC” and “set temperature to 72” work universally, but advanced features like “activate eco mode” or “set sleep timer for 2 hours” require more sophisticated skill development. Apple HomeKit support remains rare in this price range due to Apple’s stringent certification costs. If you’re deep in the HomeKit ecosystem, you’ll need to bridge through Home Assistant or settle for more limited Siri shortcuts—hardly ideal for a plug-and-play experience.
App Functionality and User Experience
The companion app makes or breaks the smart experience. Download it before buying (most are free) and explore the interface. Quality indicators include: customizable scheduling with multiple daily periods, filter cleaning reminders, usage history graphs, and firmware update capabilities. Red flags include mandatory account creation with excessive data permissions, frequent crashes in recent reviews, and a lack of offline manual control. The best budget apps offer local network control when the internet goes down—a feature that separates thoughtful engineering from checkbox feature-ticking.
Types of Smart ACs in Your Budget
Window Units: Power and Efficiency
Window air conditioners dominate the sub-$500 smart category, offering the best BTU-per-dollar ratio. Their fixed installation creates a tight seal, maximizing efficiency and minimizing noise leakage. Most smart window units in this range handle 6,000-10,000 BTU, making them ideal for bedrooms and small living spaces. The installation learning curve steeper than portables—you’ll need to manage tilt angles for proper drainage, secure mounting brackets, and insulate gaps. But once installed, they run quieter and more efficiently than their portable counterparts, with many achieving noise levels below 52 decibels.
Portable Units: Flexibility Trade-offs
Portable smart ACs offer plug-and-play convenience but extract a premium in efficiency and noise. The same $400 that buys a 10,000 BTU window unit typically gets you only 8,000 BTU in portable form, with CEER ratings 15-20% lower. The exhaust hose radiates heat back into the room, and the indoor compressor location increases noise to 55-60 decibels—conversation-interrupting levels. However, for renters, casement windows, or multi-room cooling needs where you move the unit seasonally, portability justifies the compromises. Look for dual-hose designs (rare under $500 but occasionally available on sale) which improve efficiency by using outside air for condenser cooling.
Emerging Categories
Innovation creeps into the budget segment through unconventional designs. Saddle-style window units that straddle the sill free up window space and reduce noise. U-shaped designs place the compressor outside the window, dropping indoor noise to whisper-quiet 42-45 decibels. While these advanced form factors typically exceed $500 at launch, previous generation models frequently drop into budget territory during clearance sales. Keep an eye on manufacturer refurbishment programs too—last year’s premium smart features often appear in certified refurb units under $400 with full warranties.
Installation Realities for DIYers
Window Mounting Requirements
Smart features can’t compensate for poor installation. Measure your window’s physical opening and maximum weight capacity before falling in love with any unit. Most budget window ACs require a minimum 13-inch vertical opening and support up to 85 pounds. Check for nearby outlets—manufacturers recommend dedicated 115V circuits for units above 10,000 BTU. The electrical code requires a 3-prong grounded outlet within 6 feet; extension cords void warranties and create fire hazards. Weather stripping and foam insulation tape, often omitted from budget packaging, prove essential for preventing air leaks that sabotage efficiency.
Portable AC Venting Challenges
Portable units demand more than just rolling them into place. The exhaust hose, typically 5-7 feet long, must run in a straight line with minimal bends—each 90-degree bend reduces efficiency by 5%. The window kit needs to fit your specific window type; casement and sliding windows often require custom plexiglass solutions not included in the box. Budget portables frequently skimp on hose insulation, causing the exhaust to heat your room. Wrap it with inexpensive foil duct insulation from the hardware store—a $10 upgrade that dramatically improves performance. Also, plan for condensate removal: while many units claim “self-evaporation,” humid climates will overwhelm this feature, requiring manual draining or a small pump.
Electrical Safety Considerations
That $350 price tag doesn’t include an electrician, but you might need one. Units above 8,000 BTU can draw 7+ amps continuously, stressing older wiring. If your circuit breaker trips during the compressor startup surge, you’re overloading the circuit. Budget smart ACs rarely include built-in surge protection—a critical omission during summer storms. Invest in a $15 appliance-grade surge protector with at least 1000 joules rating. Never use a power strip or multi-tap adapter; these create fire hazards with high-draw appliances. Check your home’s wiring: aluminum wiring from the 1970s requires special outlets and poses compatibility issues that void warranties.
Performance Metrics That Impact Daily Use
Noise Level Benchmarks
Sound pressure levels measured in decibels (dB) determine whether your smart AC becomes a sleep aid or a sleep disruptor. In the sub-$500 category, window units typically range from 50-58 dB on high—comparable to a refrigerator hum. For bedrooms, prioritize models advertising “sleep mode” below 50 dB. Portable units run louder, usually 55-65 dB, due to indoor compressor placement. Pro tip: read user reviews specifically mentioning noise, as manufacturers often measure dB from unrealistic distances. The location matters too—installing a window unit in a vinyl frame versus wood studs can amplify vibrations, adding 3-5 dB of structural noise.
Cooling Speed and Airflow Patterns
Smart features should include adjustable louvers and multiple fan speeds—not just on/off control. Look for units offering at least 3 fan speeds plus an auto mode that modulates based on temperature differential. The best budget models include a “follow me” function where the remote’s built-in sensor communicates ambient temperature, adjusting cooling accordingly. Airflow direction matters: vertical oscillation helps distribute cool air evenly, preventing hot spots. Check the CFM (cubic feet per minute) rating—higher numbers mean faster cooling. A 6,000 BTU unit should move at least 180 CFM; 10,000 BTU models need 250+ CFM for effective circulation.
Dehumidification Capabilities
Air conditioning inherently removes moisture, but some units excel at it. Check the pints-per-hour dehumidification rating, especially if you live in a humid climate. Budget smart ACs typically remove 1.5-3 pints per hour—adequate for moderate humidity but insufficient for tropical conditions. The smart angle here involves humidity-based triggers: premium budget models can activate cooling when relative humidity exceeds a set threshold, independent of temperature. This feature, sometimes called “dry mode,” prevents that clammy feeling and protects against mold. If your climate sees summer humidity above 60%, prioritize this capability over fancy scheduling features.
Advanced Smart Capabilities Worth Considering
Scheduling and Automation Depth
Basic scheduling lets you set on/off times, but sophisticated automation responds to multiple triggers. Look for apps supporting conditional logic: “Turn on at 5 PM, but only if outdoor temperature exceeds 80°F” or “Switch to eco mode after 10 PM on weekdays.” The best budget platforms allow different schedules for each day of the week, accommodating irregular work shifts. Some units learn your manual adjustments over time, creating adaptive schedules—though this AI-like feature remains rare under $500. Test the app’s scheduling interface before purchasing; clunky, slow interfaces indicate poor backend architecture that’ll frustrate you daily.
Geofencing and Location-Based Controls
Geofencing uses your phone’s location to automate operation based on proximity. Drive within 2 miles of home, and the AC kicks on to pre-cool your space. Leave for work, and it automatically switches to energy-saving mode. This feature, once premium-only, now appears in budget apps but with limitations: single-user tracking (confusing multi-person households), GPS battery drain, and occasional false triggers from location inaccuracies. Implementation quality varies dramatically—some apps refresh location every 5 minutes, creating delays, while others use cellular tower triangulation for faster response. If geofencing appeals to you, search app reviews specifically for “location” mentions to gauge real-world reliability.
Third-Party Integration and IFTTT
IFTTT (If This Then That) support unlocks creative automation: “If my Nest thermostat detects I’m away, turn off the portable AC” or “If local weather drops below 70°F, switch to fan-only mode.” Native IFTTT channels indicate a company’s commitment to open ecosystems. Budget brands increasingly offer this, though sometimes through unofficial community applets rather than first-party support. SmartThings, Hubitat, and Home Assistant integration provide similar benefits for home automation enthusiasts. Check community forums for user-created drivers—popular budget models often have robust community support that surpasses official capabilities.
Hidden Ownership Costs
Maintenance and Filter Expenses
That $379 purchase price excludes ongoing maintenance. Washable filters, common in budget units, require cleaning every 2-4 weeks during heavy use. Replacement filters, if needed, cost $15-30 annually. Some smart apps track filter status based on runtime hours—a genuinely useful feature that prevents efficiency-robbing clogs. Check filter accessibility before buying; units requiring screwdriver removal for basic cleaning quickly become neglected. The condenser coils need annual vacuuming—budget models with rear-facing coils behind flimsy grilles make this task frustrating. Factor in a $5 can of coil cleaner and 30 minutes of your time each spring.
Energy Consumption Monitoring
Real-time energy tracking separates thoughtful smart ACs from gimmicky ones. Quality apps display current wattage draw, estimated monthly cost, and historical usage patterns. This data reveals inefficiencies: that 30-minute pre-cooling might cost $0.15 daily, adding $45 to your summer bill. Some units integrate with utility time-of-use rates, automatically shifting heavy cooling to off-peak hours. While rare under $500, a few budget brands partner with energy rebate programs, offering $25-50 incentives for enrolling in demand response programs where the utility can briefly cycle your AC during peak load events.
Warranty Limitations
Budget smart ACs typically carry 1-year full warranties, with 5-year coverage on the sealed system (compressor, evaporator, condenser). However, “smart” components often fall under shorter 90-day warranties. Read the fine print: some brands require online registration within 30 days, while others demand original receipts and serial numbers. Third-party sellers on marketplace sites may not honor manufacturer warranties. Consider the cost of extended warranties carefully—they often exceed 25% of the purchase price, making replacement more economical than repair for sub-$500 units. Keep original packaging for at least the warranty period; many companies require it for returns.
Brand Reliability in the Budget Segment
What to Expect at This Price Point
The sub-$500 smart AC market includes established appliance brands, white-label manufacturers, and direct-to-consumer disruptors. Established brands offer proven reliability but often lag in smart feature innovation. Newer brands pack impressive app functionality but may lack long-term durability data. Check the company’s history: brands with 5+ years in smart appliances have worked out firmware bugs and server reliability issues. Look for FCC certification numbers on product listings—this indicates proper radio frequency testing, often skipped by fly-by-night brands. The sweet spot: companies with appliance manufacturing experience who’ve recently expanded into smart features, offering both reliability and modern functionality.
Researching Company Reputation
Dig deeper than star ratings. Search for “[Brand Name] server outage” or “[Brand Name] app not working” to uncover chronic cloud infrastructure problems. Check if the company provides firmware release notes—regular updates indicate active development and security patching. The Better Business Bureau profile reveals customer service responsiveness; look for patterns in complaint resolution. Reddit’s r/homeautomation and HVAC forums offer unfiltered user experiences. Pay attention to comments about app updates breaking functionality—a sign of poor quality assurance. Companies that maintain active social media support channels typically resolve issues faster than those relying solely on email tickets.
Common Buyer Mistakes to Avoid
The BTU Mismatch Problem
Oversizing causes short-cycling: the AC cools too quickly, shuts off, then restarts minutes later. This prevents proper dehumidification and wears components faster. Undersizing leads to continuous operation, sky-high electric bills, and premature compressor failure. The most common mistake? Ignoring insulation quality. A poorly insulated 300 sq ft room might need 10,000 BTU despite calculators suggesting 6,000. Conversely, a well-insulated basement might stay comfortable with 5,000 BTU. When in doubt, size down slightly—continuous operation at 80% capacity beats constant on/off cycling at 150% capacity.
Wi-Fi Signal Strength Oversights
That perfect AC means nothing if it can’t maintain a stable connection. Metal window frames, concrete walls, and distance from your router create dead zones. Test your phone’s Wi-Fi at the exact installation spot; if you struggle to load a webpage, your smart AC will too. Some users resort to Wi-Fi extenders, but these introduce latency that can delay commands by 5-10 seconds. Powerline adapters with Wi-Fi offer better reliability for fixed installations like window units. For portables, consider units with Bluetooth backup control—limited range but reliable when Wi-Fi fails.
Misleading “Smart” Marketing Claims
“Works with Alexa” doesn’t guarantee comprehensive voice control. Some budget units only support on/off and temperature adjustment, lacking mode changes or fan speed control. “Smart scheduling” might mean simple timer functions rather than conditional automation. “Energy saving” could refer to a basic eco mode that merely limits fan speed, not true adaptive cooling. Scrutinize app screenshots in product listings—if they only show a power button and temperature slider, the smart features are superficial. True intelligence includes sensor data, usage analytics, and rule-based automation. When in doubt, search YouTube for “[Model Number] app walkthrough” to see actual functionality before committing.
Maximizing Value and Longevity
Seasonal Maintenance Routines
Treat your smart AC like a car requiring regular tune-ups. Each spring, remove and deep-clean the filter with mild detergent. Vacuum the condenser coils from the outside, being careful not to bend the delicate fins. Check the window seal integrity; compressed weatherstripping from winter storage needs replacement. Run the unit on fan-only mode for 30 minutes to dry internal components before storage, preventing mold. Store portables upright—laying them down can cause compressor oil migration, creating startup damage. These simple steps add 3-5 years to the typical 7-10 year lifespan, stretching your $400 investment to under $50 annually.
Optimizing Placement for Efficiency
Location dramatically impacts performance. For window units, install on the shadiest side of your home—north-facing walls are ideal. Ensure at least 20 inches of clearance around the outdoor condenser; blocked airflow reduces efficiency by 15-20%. Inside, position the unit so airflow isn’t obstructed by curtains or furniture. For portables, keep the exhaust hose as short and straight as possible; each foot of extra hose reduces cooling capacity by 1%. Place the unit centrally in the room, not pushed against a wall. Smart features like remote temperature sensors work best when the unit isn’t fighting against its own temperature stratification.
Timing Your Purchase Strategically
Seasonal Pricing Trends
Air conditioner pricing follows predictable cycles. January through March sees the lowest prices as retailers clear inventory, with discounts of 25-35% off summer MSRP. April brings new model announcements, further depressing last year’s prices. May through July commands full retail pricing—avoid buying then unless absolutely necessary. August offers the first summer clearance sales, typically 15-20% off. September through December sees sporadic deals as stock dwindles. For maximum selection and savings, shop late February through early March. Set price alerts on comparison sites; many budget models see 30% price drops during these off-peak windows.
Holiday Sale Opportunities
Black Friday and Cyber Monday increasingly feature smart AC deals, though inventory is limited. Memorial Day and July 4th sales offer modest 10-15% discounts but include bundle deals like free installation kits or extended warranties. Earth Day (April 22) sometimes triggers energy efficiency promotions with utility rebate stacking opportunities. Amazon Prime Day in July has become a major AC sales event, with exclusive budget models launched specifically for the sale. Pro tip: create accounts on major retailer sites beforehand, saving your payment info for lightning-fast checkout during limited-stock sales events.
Setting Up Your Smart Home Integration
Router and Network Preparation
Before installation, optimize your network. Create a dedicated 2.4GHz SSID for smart home devices—this prevents dual-band routers from pushing the AC to 5GHz, which it can’t use. Assign static IP addresses through your router’s DHCP reservation to prevent connection drops during IP renewals. Enable WPA2 security; some older budget units choke on WPA3. If you have 20+ Wi-Fi devices, upgrade to a router supporting 50+ concurrent connections—budget ACs sometimes hold connections open unnecessarily, exhausting cheaper router connection tables. These network optimizations eliminate 90% of “smart” connectivity complaints.
Creating Automation Routines
The real power emerges when your AC collaborates with other devices. Create scenes like “Summer Evening” that dim lights, closes smart blinds, and sets the AC to 74°F. Use temperature sensors in multiple rooms to trigger the AC only when your home office exceeds 78°F, ignoring the cooler bedroom. Pair with smart plugs to measure actual energy consumption, creating rules that shut off the AC if it draws excessive power indicating a malfunction. The IFTTT integration in many budget units allows creative triggers: “If CO2 levels rise above 1000ppm (from a separate air quality monitor), increase fan speed to circulate air.” This ecosystem approach transforms a simple appliance into an intelligent climate management system.
Frequently Asked Questions
1. Can I really get a reliable smart AC for under $500, or am I sacrificing too much quality?
Absolutely, but reliability depends on prioritizing core components over flashy features. Focus on units from established manufacturers where the smart features are value-adds rather than the main selling point. These models typically use proven compressors and coils with newer Wi-Fi modules. The key is reading recent reviews specifically about longevity; models with 2+ years of firmware updates and consistent app performance indicate stable products. Avoid first-generation smart features from brands new to connectivity.
2. How much will a budget smart AC actually add to my electricity bill?
A typical 8,000 BTU unit running 8 hours daily costs $25-45 monthly, depending on your electricity rate and climate. Smart features can reduce this by 15-25% through scheduling and eco modes. The real savings come from avoiding cooling an empty home—geofencing and scheduling ensure you only pay for cooling when needed. Monitor the first month’s usage through the app, then adjust schedules to optimize around your utility’s peak and off-peak rates for maximum savings.
3. Do I need a special router or internet speed for these smart ACs to work properly?
No, but stability matters more than speed. Any broadband connection works, but the AC needs consistent 2.4GHz Wi-Fi. A basic dual-band router is sufficient if placed within 30 feet and a few walls of the unit. For detached garages or backyard offices, a mesh network node nearby ensures reliable connectivity. Latency below 100ms is ideal; higher latency causes delayed app responses. The AC uses minimal bandwidth—less than 50MB monthly—so it won’t impact your other devices.
4. Will my smart AC work during a power outage or internet outage?
During power outages, the unit obviously won’t run, but crucially, it should resume your previous settings when power returns. Quality models include auto-restart with memory retention. Internet outages are more nuanced: most budget units revert to manual remote control, losing app and voice functionality until connectivity restores. Some premium budget models offer local network control via Bluetooth or LAN, maintaining basic scheduling. Check reviews for “offline mode” mentions if this concerns you.
5. How difficult is installation really? Can I do it myself?
Window units require basic DIY skills: measuring, lifting 40-80 pounds, and using a screwdriver. Two people make installation safer and easier. Most users complete it in 45-90 minutes. Portable units are simpler—just attach the window kit and plug in—but the hose setup can be finicky. If you’re not comfortable lifting heavy objects or working at heights, hire help. Many retailers offer installation for $75-150, which includes proper sealing and electrical safety checks.
6. What’s the difference between a smart AC and a regular AC with a smart plug?
Smart plugs only provide on/off control and basic energy monitoring. They can’t adjust temperature, change modes, or access internal sensors. A true smart AC offers granular control over setpoints, fan speeds, and operational modes. More importantly, smart ACs provide internal diagnostics, filter alerts, and can modulate cooling rather than just cycling on/off. This precision saves energy and improves comfort. However, for simple window units without electronic controls, a smart plug can be a budget hack—just ensure the AC resumes operation after power loss.
7. How long do budget smart ACs typically last?
With proper maintenance, expect 7-10 years of service. The smart components (Wi-Fi module) often fail before the mechanical parts, typically around year 5-6. Fortunately, the AC continues working manually if the smart features die. Budget units may have slightly shorter lifespans than $800+ models due to thinner gauge metal and simpler compressors, but the difference is usually only 1-2 years. Regular filter cleaning and seasonal storage dramatically impact longevity. Units run continuously in humid climates may need compressor replacement at year 8, which often isn’t economical.
8. Can I integrate a budget smart AC with my existing smart home system?
Yes, but integration depth varies. Alexa and Google Home work seamlessly for voice control. For platforms like SmartThings, Hubitat, or Home Assistant, check community forums for custom device handlers—popular budget models often have robust community support. Full HomeKit integration is rare under $500, though HomeBridge software can bridge the gap for tech-savvy users. IFTTT support enables creative cross-platform automations even without native integration. Always verify the specific model number’s compatibility; similar-looking units can have completely different connectivity chips.
9. Are there security risks with budget smart ACs connecting to my network?
Any internet-connected device poses potential risks, but reputable brands implement basic security: encrypted cloud connections, regular firmware updates, and no open ports. Risks increase with obscure brands lacking security track records. Protect yourself by: creating a guest network for IoT devices, using strong unique passwords, enabling two-factor authentication on the app if available, and checking for firmware updates monthly. Avoid units requiring overly broad app permissions (access to contacts, photos, etc.). No major security breaches have targeted budget ACs specifically, but practicing good IoT hygiene is essential.
10. What should I do if the smart features stop working but the AC still cools?
First, power cycle the unit and router—this resolves 60% of connectivity issues. Check for app updates and firmware updates in the settings menu. If problems persist, try re-pairing the unit: delete it from the app, reset the AC’s Wi-Fi (usually holding a button for 5 seconds), and re-add it. Contact manufacturer support via email with your model number and description; many issues require server-side fixes. As a last resort, use the infrared remote that came with the unit. If smart features are critical and the unit is under warranty, push for replacement. Otherwise, a $30 universal smart remote with temperature sensor can restore partial automation.
