9 Best Smart AC Controllers for Mini Splits (November 2026)
The best smart AC controllers for mini splits include the Cielo Breez Breez Eco Smart AC Controller for complete mini-split control, the MOES WiFi Smart IR Remote Controller Smart for multi-device IR control, and the Sensibo Sky for climate-based automation.
On this page (4 sections)
The best smart AC controller for most mini splits is the Cielo Breez Eco, because it combines infrared remote control, temperature and humidity sensing, schedules, geofencing and voice access. That mix suits owners who want daily control without replacing the air conditioner itself.
Choose Sensibo Sky for climate-based automation, or Breez Lite when broad model support and no monthly subscription matter most. Each option takes a different approach, so the right pick depends on how you like to run the room.
Smart controllers add Wi-Fi features to mini splits that already use infrared remotes. They can help you adjust the room before you arrive, set schedules and reduce the need to find the handheld remote.
The main change is convenience rather than cooling power. Your existing unit still does the cooling, while the controller sends commands, follows rules and reports room conditions through an app.
This roundup focuses on controllers for remotely operated mini split air conditioners. If you need a wired thermostat instead, start with our guide to the best smart thermostat for mini split systems.
That distinction matters before you order anything. An infrared controller works alongside your current remote based system, while a wired thermostat connects to HVAC equipment in a different way.
For most homes, start by confirming your mini split uses an infrared remote. Then check placement, Wi-Fi coverage and whether you want simple schedules or more detailed climate rules.

Cielo Breez Eco: best smart AC controller for full control
Cielo Breez Breez Eco Smart AC Controller: Best for complete mini-split control
- Mini-split, window and portable AC support
- Temperature and humidity sensing
- Weekly schedules and geofencing
- Alexa and Google Home control
Cielo Breez Eco combines remote control, sensors, schedules, geofencing and usage history in one compact controller. It suits mini-split owners who want more than basic on and off commands.
Pros
- Temperature and humidity sensing
- Weekly schedules and geofencing
- Local power button
Cons
- Requires line of sight to the AC
- Works with IR remote-controlled systems
Cielo Breez Eco is the strongest all-around choice for a mini split with an infrared remote. It controls mini-split, window and portable AC units through Wi-Fi, with access from iOS, Android, the web, the device itself, Alexa and Google Home.
The built-in temperature and humidity sensing helps the app respond to room conditions. Weekly schedules, geofencing, zones and usage history give you more control than a basic remote repeater.
Placement matters. Cielo recommends putting Breez Eco within 6–12 ft of the AC and in its line of sight.
The device can sit on a table with its stand or mount on a wall, and it includes a local power button for use when Wi-Fi is unavailable.
Choose it when you want one controller for daily comfort, schedules and remote access. Its main limit is shared by most IR controllers: the mini split must receive the infrared signal.
MOES WiFi Smart IR Remote Controller: best for multiple IR devices
MOES WiFi Smart IR Remote Controller Smart: Best for multi-device IR control
- Controls IR air conditioners and other devices
- Smart Life/Tuya app
- Alexa and Google Assistant support
- 2.4 GHz Wi-Fi
MOES is a flexible IR blaster for a room with an air conditioner and other infrared devices. Its DIY learning function can help when your AC brand is not found in the app.
Pros
- Controls several IR device types
- DIY learning function
- No hub required
Cons
- One room is recommended
- Does not support RF devices
MOES is a useful choice when your mini split shares a room with other infrared devices. It can control air conditioners, TVs, fans, DVD players, set-top boxes and TV boxes through the Smart Life or Tuya app.
That wider scope is the main reason to consider it. A single controller can handle the entertainment and comfort devices in one space, which can simplify how you manage them from your phone.
The controller supports Alexa and Google Assistant, and its DIY learning function can copy commands when the device brand is not found in the app.
You still need to test each copied command, because a button that looks correct may not trigger the same response on the device.
MOES supports 2.4 GHz Wi-Fi and 38 kHz infrared. The stated range is up to 15 m, but infrared still needs a clear path, and the instructions recommend one smart IR controller for one room because the signal cannot pass through walls.
Placement should face the air conditioner without furniture or walls in between. It uses a USB connection for power, so choose a socket or port that stays available.
Pick MOES if you want a general room IR hub. Choose Cielo or Sensibo instead if your main goal is mini-split temperature automation with dedicated climate features.
Sensibo Sky: best for climate-based automation
Sensibo Sky: Best for climate-based automation
- Temperature and humidity-based Climate React
- Geofencing
- 7-day scheduling
- Google, Alexa and Siri support
Sensibo Sky suits buyers who want temperature and humidity rules rather than simple remote commands. It works with remote-controlled AC systems and includes a power plug and Micro-USB cable.
Pros
- Climate React automation
- 7-day programming
- Web, Android and iOS apps
Cons
- Does not support Bluetooth
- Needs direct line of sight
Sensibo Sky turns a remote-controlled mini split, window AC, portable AC or heat pump into a connected system. Its Climate React feature uses temperature and humidity preferences to manage the room's comfort target.
That approach suits people who feel uncomfortable when temperature alone looks fine. Humidity can change how a room feels, so rules based on both readings can lead to more steady comfort.
The app supports 7-day programming, conditional programming and geofencing. You can use the Android, iOS or web app, along with Google Assistant, Alexa and Siri.
Weekly programming fits households with a regular routine. Conditional rules add flexibility when weather or occupancy changes during the day.
Sensibo recommends placing the unit within 5 m or 16 ft of the AC with direct line of sight. It does not support Bluetooth, so check your network setup before installation.
Keep the infrared face clear and avoid direct sunlight or strong drafts near the sensor. Those conditions can affect readings and make automation less predictable.
The box includes Sensibo Sky, a power plug and a Micro-USB cable. Setup follows the app prompts for adding the device, selecting the room and pairing your AC remote.
Choose Sensibo Sky when humidity and temperature rules matter more than simple remote commands. For a comparison of Sensibo models, read our Sensibo Air vs Air Pro guide.
Cielo Breez Lite: best for broad mini-split model support
Cielo Breez Breez Lite Smart AC Controller: Best for broad model support
- Supports 20,000+ ductless, window and portable AC models
- Built-in temperature and humidity sensors
- Schedules and geofencing
- Alexa, Google, Siri Shortcuts, SmartThings and IFTTT
Breez Lite is a strong fit when model coverage and app control matter. It adds temperature and humidity sensing, schedules, zones and usage history without monthly subscriptions.
Pros
- Wide stated model support
- No monthly subscription
- Built-in sensors
Cons
- Requires line of sight
- Designed for IR remote-controlled ACs
Breez Lite is designed for ductless mini splits, window ACs and portable ACs, with stated support for more than 20,000 models. It automatically detects the remote during setup and does not require tools.
That broad coverage makes it a sensible first check for older or less common units. You still need to confirm your model during setup, but the detection step reduces manual work.
The built-in temperature and humidity sensors support intelligent triggers, while the app adds schedules, geofencing, zones, usage history and air filter status. It also works with Alexa, Google Assistant, Siri Shortcuts, SmartThings and IFTTT.
Those voice and automation links suit homes that already use a smart assistant. Schedules handle the routine, while geofencing can adjust the room when you leave or arrive.
Like Breez Eco, Breez Lite needs to sit within 6–12 ft and in line of sight of the air conditioner. It uses a 5V DC adapter with a USB-C cable and has an ABS body.
Place it where the mini split can receive the signal reliably. Test commands from the app before fixing the unit in place, especially if furniture may block the path later.
Keep the sensor area away from direct sunlight, heaters and exterior doors so readings stay representative. Choose Breez Lite when broad model coverage and no monthly subscription are the key buying points.
Choose Breez Eco if you want the added local control button and more complete feature set.
AC Infinity Controller 69 PRO: best for grow-space climate systems
AC Infinity Controller 69 PRO: Best for grow-space climate systems
- Controls up to 4 devices
- Temperature, humidity and VPD automation
- Bluetooth and Wi-Fi app control
- Alerts and climate data
Controller 69 PRO is aimed at coordinated environmental equipment, including fans, grow lights, humidifiers and heaters. It is not a direct IR mini-split remote, so choose it for compatible AC Infinity systems.
Pros
- Four independent device controls
- VPD programming
- Wi-Fi and Bluetooth
Cons
- Not a direct IR mini-split controller
- Best fit is an AC Infinity equipment setup
Controller 69 PRO is different from the IR mini-split controllers above. It is an environmental controller for AC Infinity devices and can control up to 4 devices, including fans, grow lights, humidifiers and heaters.
Each device can follow its own programming. That separation helps when a fan, light and heater need different responses to the same changing conditions.
Its automation uses temperature, humidity and VPD targets. Bluetooth or Wi-Fi app access adds programming, alerts and climate data, while the LCD controller measures 3.66 x 3.11 x 0.98 in.
VPD adds a plant-focused measure that combines temperature and humidity for growers. For home comfort use, the same sensors are better understood as general climate tracking.
Timers, schedules and custom transitions let equipment change gradually rather than all at once. That can suit sensitive setups where sudden shifts are not wanted.
This controller makes sense when your mini split is part of a larger compatible climate setup. It is not the direct choice for sending infrared commands to a standard room mini split.
Check that every device you plan to connect is compatible before ordering. A controller designed for coordinated equipment will not add app control to an incompatible air conditioner remote.
Pick it for coordinated grow-tent or equipment control. For a normal living room air conditioner, choose a dedicated IR controller instead.
AC Infinity Outlet AI: best for switched climate equipment
AC Infinity Outlet AI: Best for switched climate equipment
- 4 individually controlled outlets
- AI climate targeting
- Temperature, humidity and VPD tracking
- 1,800W maximum capacity
Outlet AI suits equipment that can be controlled by power, such as heaters, fans, pumps and some home HVAC devices. It does not replace an IR controller for a mini split that needs remote commands.
Pros
- Four individually controlled outlets
- Surge protection
- Wi-Fi alerts and charts
Cons
- Not an IR remote controller
- Optional sensors are sold separately
Outlet AI controls equipment through four individually managed outlets. It can apply schedules, timers and climate triggers to compatible heaters, fans, pumps, lights and other devices.
Individual control is the key advantage here. One outlet can follow a schedule while another responds to temperature or humidity, instead of forcing all equipment to run together.
The unit supports 1,800W maximum capacity, 15 A current and built-in surge protection. Its Wi-Fi app provides alerts, charts and climate information, while dual-zone temperature, humidity and VPD tracking support more advanced setups.
Stay within the stated capacity for each connected item. Surge protection helps with electrical protection, but it does not turn incompatible equipment into a smart device.
Optional sensors are sold separately for expanded setups. Dual-zone tracking can help when two areas need different rules, though basic use may need only one zone.
This is not an infrared remote controller for a mini split. It is a better fit when the equipment can be controlled by switching power and your setup benefits from separate outlet rules.
Plan cable routing and label each outlet before setup. Clear labels make schedules and triggers easier to adjust later.
Choose Outlet AI for a multi-device climate system. Do not choose it as a direct replacement for a Cielo or Sensibo controller.
hejhncii XHY-S: best for a direct remote replacement
hejhncii Home Appliance Supplies: Best for a direct remote replacement
- Replacement remote for GYKQ-52 air conditioner
- 18 buttons
- LCD display
- ABS construction
This hejhncii remote is for replacing a compatible GYKQ-52 air conditioner remote, not for adding Wi-Fi. It makes sense when the original remote is missing or damaged and smart control is not needed.
Pros
- No programming required
- 18-button layout
- Compact replacement remote
Cons
- Not a Wi-Fi controller
- Compatibility is limited to the stated AC remote type
The hejhncii XHY-S is a replacement air conditioner remote for the GYKQ-52 system. It has 18 buttons, an LCD display and an ABS body, with an infrared range of up to 10 m.
The layout keeps common controls within easy reach. An LCD helps you see the selected mode and temperature without guessing from button presses.
No programming is required, and batteries are not included. That makes this a simple fix when the original remote is missing or damaged, but it does not add Wi-Fi, schedules, app control or voice access.
You will need to insert compatible alkaline batteries before first use. Keep spare batteries nearby if the AC is used often through warm weather.
The ABS body is described as wear resistant. Handling it like a normal handheld remote should suit everyday use around the home.
Range depends on a clear path to the receiver. Pointing the remote directly at the indoor unit gives more reliable responses than aiming from another room.
Choose it when you need a compatible handheld remote and do not need smart features. Confirm that your AC uses the GYKQ-52 remote type before ordering.
CoolBot Pro: best for walk-in cooler conversion
CoolBot Pro 34ºF Walk-in Cooler Controller: Best for walk-in cooler conversion
- Wi-Fi monitoring and alerts
- Supports cooling down to 34°F under proper conditions
- Works with compatible window or mini-split ACs
- 110V operation
CoolBot Pro is a specialized temperature controller for turning a properly insulated room into a walk-in cooler. It is not a normal comfort controller for a home mini split.
Pros
- Remote monitoring and alerts
- Designed for cold storage
- No specialized wiring required
Cons
- Requires a compatible AC and insulated room
- Not intended for ordinary room comfort control
CoolBot Pro is a specialized controller for converting a properly insulated room into a walk-in cooler with a compatible window or mini-split AC. It can help maintain temperatures as low as 34°F under proper conditions.
That target is far below normal room comfort settings. It is designed for cold storage, where steady low temperatures matter more than feeling comfortable.
Wi-Fi access lets you monitor and adjust the system from a phone, computer or tablet. Alerts help you respond to temperature changes, which matters more for produce, meat, dairy, flowers or beverages than ordinary room comfort.
Remote monitoring is useful when the cooler is in a shed, garage or separate room. Early alerts can help you act before stored items are affected by warming.
Insulation and a compatible air conditioner are essential parts of the setup. The controller cannot reach its intended range in a poorly insulated space or with an unsuitable unit.
This controller is not intended to make a household mini split smarter for cooling a bedroom or living room. It belongs in a cold-storage project with the required insulation and compatible air conditioner.
Installation is described as straightforward with no specialized tools or wiring. Follow the step by step instructions and test the system before loading it with perishable items.
Choose CoolBot Pro only when your goal is refrigeration rather than home comfort control.
Broadlink RM4 Mini with HTS2: best for broad IR coverage
Broadlink RM4 Mini IR+HTS2 Temperature Humidity Sensor: Best for broad IR device coverage
- IR control for AC and other devices
- Temperature and humidity sensor
- Alexa compatibility
- Cloud IR database
Broadlink RM4 Mini with HTS2 fits buyers who want one Wi-Fi IR controller for several household devices. Its broad device support is useful, but confirm the exact mini-split remote match before choosing it.
Pros
- Supports up to 15 devices
- Temperature and humidity sensor
- Can learn unmatched remotes
Cons
- Exact AC compatibility needs checking
- Less mini-split focused than Cielo or Sensibo
Broadlink RM4 Mini with HTS2 is a Wi-Fi IR controller for air conditioners, televisions, set-top boxes, DVD players, fans and other infrared devices. It supports up to 15 devices and includes temperature and humidity sensing.
That device limit suits a home with several infrared appliances. One controller can reduce the number of remotes you need to reach for in a shared room.
Its cloud IR database covers many device types, and the controller can learn a remote when the exact model is not found. Alexa compatibility adds voice access for supported commands.
The learning option is a useful fallback for less common brands. Test each learned command after setup, since some functions may need adjustment to work as expected.
Temperature and humidity sensing adds context for automation. The sensor should sit in the room where conditions matter, away from direct sunlight and heat sources.
Broadlink suits a home with several IR appliances. Before choosing it for a mini split, confirm that the app can match or learn your specific remote.
Placement needs a clear infrared path to each device where possible. Walls and cabinets can block signals, so a central position often works better than a hidden one.
Choose it for broad household IR coverage. Choose Cielo or Sensibo when you want features built around mini-split scheduling and climate control.
What should you check before buying a smart AC controller?
The main checks are infrared compatibility, line-of-sight placement, Wi-Fi support and the type of automation you need. A smart AC controller cannot send commands through walls if the mini split cannot receive its infrared signal.
Does your mini split use an infrared remote?
Most picks in this roundup work by copying or pairing with the handheld remote. Check that your mini split responds to infrared commands and keep the original remote available during setup.
Keeping the remote nearby makes pairing simpler. You can test commands as you go and confirm that the app matches the buttons on the handset.
A controller that uses IR is different from a thermostat that connects to HVAC wiring. If you're unsure about the system type, read What HVAC Systems Work with Smart Thermostats?.
That check should come before you compare features. The best controller will not help if your system needs a different type of connection.
Can you place the controller in line of sight?
Yes, but the controller needs a clear path to the mini split's receiver. Cielo recommends 6–12 ft for Breez Eco and Breez Lite, while Sensibo recommends up to 16 ft.
Place the unit where it can face the indoor head without a cabinet, wall or large object blocking the signal. Test the location before using adhesive or permanent mounting.
Do you need temperature and humidity sensing?
Temperature sensing is useful for schedules and automatic comfort rules. Humidity sensing adds another input for controllers such as Cielo Breez Eco, Breez Lite and Sensibo Sky.
A separate controller sensor does not replace every HVAC sensor. Use the controller's readings as part of its automation and check the room conditions if comfort seems different from the app target.
Is 2.4 GHz Wi-Fi available?
Several smart IR controllers use 2.4 GHz Wi-Fi. MOES specifically supports 2.4 GHz, and Sensibo's setup information also points to 2.4 GHz Wi-Fi.
Check your router settings before setup. A controller may fail to connect when the required network band is unavailable or when the device is too far from the router.
Are you controlling one AC or several devices?
Choose a dedicated mini-split controller when one air conditioner is the main goal. Choose MOES or Broadlink when you also want to control other infrared devices in the same room or home.
Power-based controllers such as AC Infinity Outlet AI solve a different problem. They switch compatible equipment through outlets instead of sending the remote commands used by most mini splits.
How do you set up and use a smart mini-split controller?
Setup usually means powering the controller, connecting its app to Wi-Fi, pairing the AC remote and placing the unit where the mini split can see it. After setup, start with a simple schedule before adding geofencing or climate rules.
A simple schedule helps you learn how the controller responds. Once basic on, off, mode and temperature commands work reliably, you can add more detailed automation with more confidence.
Keep the original remote nearby while pairing. If the app cannot identify the exact remote, use a supported learning function where available, then test power, temperature, mode and fan commands.
Test each function in turn and watch the indoor unit for the correct response. Small mismatches during pairing are easier to fix at this stage than after the controller is mounted.
Use schedules that match your normal routine. Geofencing can turn an AC on or off based on location, but check the rule carefully so an unexpected phone location does not change the room at the wrong time.
If your phone location is often inaccurate, a fixed schedule may be more dependable for daily use.
Clean dust from the controller and keep its infrared face unobstructed. If commands become unreliable, check power, Wi-Fi, the app connection and the controller's distance from the indoor unit.
Dust, moved furniture and a loose power cable are common causes of missed commands. A quick check of placement can often solve the problem without resetting the whole setup.
Voice control can be added after the app connection is stable. Use clear commands for power, mode and temperature so the assistant passes the right instruction to the controller.
If several people use the system, agree on shared schedules and setpoints. That reduces conflicting changes and keeps the room closer to the routine you intended.
For basic air-care planning, our guide to what is an AC filter MERV rating explains why filter labels matter, even though a smart controller does not replace filter maintenance.
Smart control manages when the unit runs, not how clean the air is. Regular filter checks and basic unit care still matter for comfort and performance.
Which smart AC controller is best for your mini split?
The Cielo Breez Eco is the best smart AC controller for mini split owners who want the broadest comfort controls in one device. Its temperature and humidity sensing, schedules, geofencing, usage history and voice support make it the most complete fit here.
That combination suits households with a regular routine and changing occupancy. Schedules handle predictable hours, while geofencing and sensors help when the day does not follow the plan.
Choose Sensibo Sky if Climate React and humidity-based automation are your priority. Choose Breez Lite if you want broad stated model support and no monthly subscription.
Sensibo Sky places more emphasis on reacting to room conditions. Breez Lite places more emphasis on compatibility and straightforward app control for a wide range of units.
Choose MOES or Broadlink when you want one IR controller for several household devices. Choose AC Infinity products for compatible equipment systems, hejhncii for a direct remote replacement, and CoolBot Pro only for a walk-in cooler project.
Those picks solve different problems from standard mini-split comfort control. Matching the controller type to your equipment matters more than adding every available feature.
Before buying, confirm infrared compatibility and line-of-sight placement. Also check that your Wi-Fi network supports the band the controller needs during setup.
Start with the simplest automation that fits your routine. A reliable schedule or basic climate rule will give better daily value than a complex setup you rarely adjust.

Frequently asked questions
What is the best smart AC controller for a mini split?
The Cielo Breez Eco is the best smart AC controller for most mini splits in this roundup because it combines IR control, temperature and humidity sensing, schedules, geofencing, app access and voice control. Sensibo Sky is another strong choice if climate-based automation is your main priority.
Do smart AC controllers work with every mini split?
No. Most smart AC controllers in this guide need a mini split with an infrared remote and a clear line of sight.
Check the controller's compatibility support before buying, especially for older or less common AC brands.
A wired thermostat is a different product type.
Our guide to what HVAC systems work with smart thermostats explains the difference.
Where should you place a smart mini-split controller?
Place an infrared smart controller where it can face the mini split without obstructions. Cielo recommends 6–12 ft for Breez Eco and Breez Lite, while Sensibo recommends up to 5 m or 16 ft.
Avoid placing the controller behind furniture or where the AC cannot see its infrared signal.
Can a smart AC controller replace a mini-split thermostat?
A smart AC controller can add app, schedule, voice and remote control to an infrared mini split, but it does not connect like a wired thermostat. Read what is a mini split thermostat before deciding which type fits your system.
Should you buy an IR controller or a smart thermostat?
Choose an IR controller when your mini split already uses a handheld infrared remote. Choose a compatible wired or system-specific thermostat when the equipment supports that connection and you need thermostat-style control.
The best smart thermostats for mini splits guide compares that route.
