The T9 was easy to set up. The 'smart' aspect of it only includes remote control from the app but it doesn't provide any reporting like some other smart thermostats do. I had to turn off Notifications because it was beeping every time the thermostat dropped off WiFi which happened occasionally. Fortunately it would always reconnect by itself. We wanted install this on a junction box but the T9 doesn't come with the adapter that you need for that so we had to improvise. If you're mounting on drywall then it will be fine.
I would not recommend this to anyone. I own an IT company and with the manufacturers support we could not get these devices to work unless I installed a router from 10+ years ago. It constantly fell offline and made it difficult to work with.
The reason for my purchase of T9 was peace of mind. Recently our heat pump had some mechanical issues. We travel for long periods of time and with a regular thermostat our pipes could have been frozen from this issue and we would have returned home to a disaster. Love this thermostat.
Amazing and Simple system to use. Only thing is to make sure that your unit has the C (common) wire hooked up. If this is not it can be a little tricky to install but once it is the systems ease of use is amazing. I purchases extra sensors for around the house and it makes the average number of them to keep the correct temp
Very easy to install and well written instructions. It was nice to view online videos of the installation process that matched whatwas on the thermostats screen.
All the features worked as advertised including one remote sensor, setup could not have been easier.
