Breez Lite | Smart AC Controller for Mini-Split, Window & Portable Air Conditioners & Heat Pumps | Free App, No Subscriptions | Alexa, Google, Siri Shortcuts, SmartThings, IFTTT (Black)

We got these to manage our mini split AC units throughout the house. You need one puck for each AC unit, as it controls them through the individual remote control signal. The initial setup took about 30 min—plug them in, connect the pucks to the home wifi and app via bluetooth, clone the remote control signal, and calibrate the puck to the actual room temp. Once they are set up, you can control them from anywhere, since they are connected via wifi.I bought these because our house would get humid when the AC shut off cooling air when it reached the set temperature and just blow humid air nonstop the rest of the time. I was able to set up the “comfy range” settings to automatically turn the AC units on and off when the room reaches a certain temperature, and this has dramatically improved the humidity inside. This setting might be harder on our mini split system since it’s not designed to turn on and off like central air, but it certainly fixed the humidity problem.You can set up the schedule for different comfy settings for different times of day, i.e. cooler overnight for bedrooms and warmer during the day when they’re not occupied. It took some trial and error to get the right temp settings and schedule for each AC zone but once I worked it out, I was able to set it and forget it. You can also set up comfy ranges for humidity, and it will turn on the dehumidifier mode when the humidity percentage reaches the set level.We’ve had these for about 2 1/2 months, through the worst of the summer heat into the cooler early fall, and so far they are doing great. Well worth the money for the convenience and functionality.

Fast setup and easy to use app, however, after the 30 second auto remote detection connection, the app was not working to control my A/C unit ("Carrier" is the brand name, and it's a unique model that was purchased internationally). I tried to use the manual setup option, but still no luck. I called the support number, and was quickly connected to a locally based support person (local US 425 area code, spoke perfect English) who was able to apply custom settings and the app worked right away. The support person was very friendly and easy to work with - he said that one some unique models they need to manually apply certain settings. Once the app worked correctly, using all the custom setting is very easy, and I'm very happy with my purchase, and plan to purchase additional units to use in different rooms.

I bought 3 of these to regulate/manage temps for my STR several months ago and wanted to give it some time before I reviewed them. They work just as described and I can now confidently control my Mini Split units (I have 3) at any time and from any where as long as there is power and wifi at the house. It allows me to turn on and off, control temps, heat or cool, even fan settings. These devices are already saving me big money on my energy bill. I am very pleased and would recommend to anyone looking for more control of their STR property.

Worked out of the box with two AC units, needed support for setting the third to Celsius (only autodetected the Fahrenheit version of the remote, the Celsius version can only be manually selected).Support was great, they called me back and walked me through everything, answered all my questions, thank you Jason ;)Shows (not too precise) temperature and humidity levels (both can be manually calibrated) and offers most important functions (heating or cooling mode, set temperature, set fan level, power on/off), some extra functions (like turbo mode on the Samsung AC), although I think not every function is supported for my ACs (like horizontal swing).I especially liked it that when i changed the temperature on the remote, the App instantly showed the new target temperature and sent a notification to me about it.Power usage is so minimal, that my smart socket can not even measure it.Device set-up and the app is rather convenient, worked with WiFi password and with passwordless MAC-based WiFi, worked with three very different ACs, could re-configure to another AC and/or WiFi in under a minute.If you want a remote temperature+humidity sensor and a way to start heating/cooling before you arrive to your home/garage/weekend house, or to save a penny on varying electric costs, this is a great product for you ;)Note: you'll probably need the original remote to set this up and some functions are more convenient on the original remote, so this might not be a great replacement for a lost remote.Good value for money and I have to admit I love the design ;)
