I got this to work with the Honeywell T9 thermostat, as a second sensor. The T9 averages between the two sensors, and I can set priority between the two sensors and the main thermostat. So far it’s working well to provide more even heat with less temperature swings. I’m considering buying more, but wish they were a little less expensive.I’m worried that these will stop working, based on reviews, but so far so good.

Really helps keep rooms the right temperature. It has a motion sensor so it can prioritize rooms that people are in. You can also manually set priority to one or more or all sensors

I love the Honeywell T9 thermostat and these smart sensors, they have saved me a lot of money in my AC bills each month. I ordered a new sensor recently for another room and couldn't get it to sync with the thermostat. I learned that the units have different series numbers, and some are not compatible with each other. If you're having issues getting the sync, you can call the company to confirm you have the correct series.

I have two ducted Mitsubishi inverter heat pump systems using MHK2 sometimes also known as MRCH2 thermostats. The upstairs system had the thermostat located in a poor location especially in winter. It resulted in the two bedrooms upstairs being about five degrees colder than the set point. I didn't want to put the thermostat intself in a bedroom but I needed to have a temperature sensor in one of them to read the temperature there. I temporarily moved the MHK2 to one of the bedrooms (it is wireless so easy enough to do) and confirmed that reading the temp in one of the bedrooms would get me to where I wanted to be.A few Google searches found some reddit threads that confirmed this sensor would work with the MHK2 even though it isn't listed as compatible. I ordered one from Amazon and can confirm it worked great. Download the MHK2 instructions on pairing this and setting it up (it is wireless). You basically need to sync it with the Redlink controller on your unit (which thankfully does NOT unsync the MHK2). Once synced you need to got into the MHK2 setup menu and select using this sensor (you can either use this remote sensor only--what I am doing, or an average of this sensor and the MHK2 sensor).

It works great and it’s a good fit for our Home Resideo thermostat. It’s little expensive but temperature control works good. Very easy to install.Fits to any Home aesthetics.

Easy to install; works as expected. It’s the APP that needs work to be more useful - for instance, it could easily SHOW on BOTH ‘T9’ Thermostat and phone WHICH SENSOR(s) it’s using to ‘DRIVE’ / CALCULATE the INSIDE TEMP, yet that’s BURIED in one of the settings or the ‘PRIORITY’ menu, which is NOT INTUITIVE that you need to go here to find this. There are lots of APP IMPROVEMENTS needed - both T9 and APP will show the ROOM NAME where Thermostat is located under the current inside temperature, making it completely misleading. App is VERY BUGGY TOO - it will often show BOTH WRONG INSIDE TEMP & TEMP SETTING, which requires killing app and starting it again. I have the latest iPhone 12 Pro Max and iOS version (14.7) as of write up if this review, and super fast Wifi, so neither of those are the issue (oh!, and I’m referring to this happening while I’m home - I have no way of validating if the readings are outdated once I’m not home - I can validate them at home because the app doesn’t match the thermostat)
