Breez Plus | Smart Air Conditioner Controller | WiFi Thermostat for Mini-Split, Window, Portable ACS | Alexa, Google, Siri Shortcuts, SmartThings, IFTTT | Free App | Inbuilt Temp/Humidity Sensors

I really like this thermostat / remote control. I have an Alpine ductless mini-split air conditioner in my detached garage. I was looking for a humidistat, as the AC by itself runs continuously in "dry" mode as it doesn't have a built-in humidistat. I also wanted a way to be able to remotely control my unit so that I can adjust the temperature remotely before I go out to work in the garage. The unit is very easy to set up. It took me all of 3 minutes to go from a sealed box to a working thermostat with remote control via WiFi. I was very impressed by this. The app allowed me to login with my Google profile, so this was not yet another username/password combo I needed to make. Once in, it was just a few quick steps to configure it to my AC unit. The app itself is very intuitive and has all the features I'd like to see, so far. The unit and app remind me of the approach taken by ecoBee, which I use in my home. You can set ranges and actions for either temperature or humidity levels. Given that my AC unit has a built in temperature sensor, I don't need the "comfy temperature" feature really, but the "comfy humidity" feature is very helpful to me. Additionally, you can set up a schedule like a standard thermostat where you can cycle your unit on/off or adjust temperatures based on your needs. This is nice given that there's no way to do this on the AC unit itself. WiFi reception appears to be very good. My garage is across my property from my home and WiFi, while it reaches the garage, tends to be weak. My cell phone has intermittent WiFi connectivity when I'm in the garage. This thermostat has no trouble staying connected and operating correctly, and my router reports that it has a reasonably strong connection to the thermostat. The hardware itself appears to be based on Espressif's ESP32 Arduino architecture, with which I just spent several months working. It would almost be worth buying a second one to open it up and take a look at how they developed their unit just for fun. Infrared reception to the AC unit is great. I moved it around the garage just to experiment with it, and it appears to flood the room with infrared well enough that I probably could've mounted the thermostat wherever I wanted to. In the end, I put it relatively close to the unit (but out of direct airflow) as that's what made the most sense, though. My AC unit came with a USB thumb drive WiFi controller that works with the NetHome app. I tried it, and while it's "ok", it's not the best and it has no real advanced or programmable features to speak of. This thermostat makes up for that, and I will probably disconnect the one that came with the AC unit going forward. I should not that customer service was helpful. I talked to them on the phone when I had a question about setting up the "comfy humidity" feature (which, to be fair and had I opened my eyes, I would've been able to figure out myself). They answered quickly and walked me through my question. I also talked to them via email when the app appeared to stop working. It turned out that they were having an issue with their AWS server(s) that was resolved relatively quickly. Overall, I'm extremely happy with this thermostat and will absolutely buy another one when I install my next mini-split in my other building. It's well made, easy to use, easy to set up, has plenty of features, and appears to be well supported by the folks who made it.

Several commenters have said that this device is nothing more than a way to make your AC mini-split controllable from your cell phone. But it’s more — it does have an internal temperature sensor, and it CAN operate as a thermostat, but you wouldn’t know that from the supplied printed instructions, which make no mention of the Comfy mode settings required to enable thermostat operation. I didn’t know this mode existed until I read Joe R’s comment from 11/23/2020, which sums it up nicely. I was able to get Comfy mode operational, but had several questions related to fine tuning. I selected Support from Cielo’s web site, per the printed instructions, and a live chat box popped up. I entered one of my questions, and customer service rep Mark immediately picked up. After a little back and forth, Mark decided it would be best to proceed by phone. I gave him my phone number and he called me immediately. He patiently worked with me until I both knew what to do and why. GREAT customer service! Basic setup of the Cielo app is straightforward, and is explained well in the printed instructions. After setup, to enable Comfy mode… Fire up the app, and click on the appropriate device. At the top of the device page, you can select mode — I’m using Cool. Fan Speed is obvious. Swing does work (if your AC remote supports it), but setting it isn’t obvious — you need to eventually do trial and error on the various Position settings to get the air distribution angle(s) that you want. For now don’t worry about it. At the bottom of the page click on Esaver. At the top of the next page click on Comfy Mode. Ah ha! At the top of the next page turn the slider switch on, then click on the right arrow next to it. The following page displays all the settings related to Comfy Mode. For my situation: Temperature range: 74 degrees to 74. (Operating this slider would be easier on a tablet.) If room temp falls below 74, Cielo turns off cooling by setting AC to 80 (leaving power to AC device on), while leaving fan on (Mode = Fan). Fan speed is Low. Swing is Position 2, which for my AC unit (Lennox) is the uppermost air output direction. The LED indicator on the AC unit stays On. If room temp rises above 74, Cielo turns on AC cooling. Power is On, Mode is Cool, Fan speed stays Low, Swing stays in Position 2, and LED stays on. Temperature setting sets the AC device to 73, a bit lower than my 74 range setting, to insure that the AC unit keeps cooling during this period. Alter these settings to suit your situation. Then be sure to click Done so that the Cielo app keeps your settings! I’ll leave it to you to experiment with Morning, Aternoon, Evening, and Night settings. You can have the Cielo device control for humidity instead of temperature, but note that whatever you may set up for Comfy Humidity will undo your Comfy Temperature settings! Feel free to use your regular AC remote as you desire to alter your current situation; Cielo only sends commands to the AC device once each time room temp goes above or below your Cielo range setting. It doesn’t keep fighting with what you do with your regular remote the rest of the time. If your remote won’t let you alter settings, click its on/off button. This setup into apparently applies equally to the Cielo non-display unit, which can apparently do the same job(s), but I like having the display on the Breez Plus, to track room temp and see what the Cielo app is doing.

I have tried a variety of different controllers for my Mitsubishi Mr Slim mini split and this is the only one that I have kept. Fast and easy wifi setup. Fast and easy recognition of the my Mitsubishi remote. Intuitive GUI in the app and on the Cielo Breez Plus itself. I have just got it and I can say it was super easy to configure and setup so I am very early in the process of using this. I do know that it has functionality that other controllers did not have. Most important to me is the ability to create Comfy settings which kick in based on a parameter you set. My concern has been that in the Winter when the temp plunges the auto fan setting does NOT kick in a progressively higher fan speed to offset the room temperature going down. The Comfy setting allows me to create a routine that I can preselect the fan speed and let it trigger when the room temp drops. This to me is a basic requirement of a room heater and the Cielo Breeze Plus accomplishes this where others, including the Mitsubishi remote does not. The unit stays in synch with the remote control and is wife approved. The display is excellent size and can be dimmed. I will give this a bit of time but I think I will be getting another Cielo Breeze Plus for Bosch mini split located in my basement. I am so very happy with this purchase! The cons are: it is expensive and shipping was slow (to Canada). Update: I want to clarify my comment on the device being expensive. I have since found that this company has fantastic Customer Support and the functionality of this device meets all my user requirements so I am fine with what I paid and I bought another one for my other Bosch mini split system. These are an excellent product!

Like: The Breez Plus is very easy to use and the device interface is intuitive. It works as promised with Alexa to control each mini-split in the house. Tech support was excellent in updating the firmware of the device so that Celsius was displayed instead of Fahrenheit and reflected the same capabilities as the Carrier infra-red remote for the mini-split. The app provides a ton of features beyond what the infra-red remote allowed. Now I can control according to multiple schedules for temperature settings during any day of the week or everyday of the week. The app provides a lot of good information concerning energy saving tips. Dislike: After a couple of weeks of use there isn't anything so far that I dislike about the product. It works just great!.

Follow the user manual carefully for wifi and app setup, and everything else is easy. Support both Fahrenheit and Celsius scale for temperature. I got two controllers and was even able to calibrate the humidity level on one (without any issues). Date/time scheduling works well. My only wish would be able to start/stop depending on outside temperature. Maybe if device supported Matter protocol or HomeAssistant / Hubitat integration?

I tried similar products on the market, but could not find one that can control the swing flap. This one was not working at first, but Jason from tech support gave me a call and walked through the process and did something on his end and viola it was working. Very responsive tech support! Keep up the good work!

This was really simple to setup, the step by step instructions are spot on. It’s so good that I’ll be buying another one for the heat pump in our basement suite. Looking forward to having better control over the heating in our home now, this is what our system was missing in the first place.
