Lots of great things to say about this Cielo Breez Plus product. It has a lot more functions than most devices in this space.I bought this for a VERY old Mitsubishi mini-split system. I used the Breeze Plus to replace the minimal capabilities of the original remote with SMART thermostat functions! I was able to schedule many variations of up/down temps, fan control and other combinations I needed. The app is pretty easy to use. Some of the concepts, like geofencing, are new to the novice user but well worth learning to use!The key thing I addressed was the ability to manage the room temperature by a thermostat that was NOT attached to the AC unit. There is generally a huge disparity of temperatures across any room, and the mini split thermostat (on the unit) is generally up high in the hottest section of the room. I wanted to manage the temperature in the room based on the temperature at a central location. The Cielo line of products are one of VERY FEW that have their device act as a 'remote' smart thermostat.Another aspect that is very reliable with this device is it's connection to the internet. If you want to manage or 'status check' what's going on at home remotely the home device connection to the internet is key. (Of course, sometimes issues are with the network.)I changed out my old, dead mini-split and installed a new Fujitsu basic mini split, dual zone. The remote has some features that are awkward to use. Unfortunately, the remote does not have any form of 'follow me' feature to make it act like a remote thermostat. So I moved my Cielo Breeze Plus to the new Fujitsu. I plan to purchase a 2nd unit to manage the new Fujitsu unit I put in the bedroom. Again... I want to manage the temperature in a SMART fashion based on the temperature in a central location of the room.I had a small startup problem adding the Breeze Plus to the Fujitsu so I called Cielo support. They answered quickly and solved the quirk immediately. I really appreciate such responsive support!!

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?

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!.

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!

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.
