I like the thermostat itself, but the app is very basic and doesn't do all that it should. I have still not been able to link the app/thermostat to Alexa. Have given up trying. Reading other reviews, it looks like I'm not alone. Seems to also be some communication issues between the app and thermostat. Not happy with the app at all, at this point.
We upgraded from the T5 model, very pleased with the T9. I really enjoy the goefencing option that is offered. There are even accessories that can be purchased to zone rooms, which will be our next addition!
Works great, really like the intermittent fan run setting. It along with the remote sensors help to keep the whole house temperature more consistent, without cooler or warmer areas in the house.
After installation the setup was easy. Very convenient to use, especially when away from home. Would recommend for those looking to implement smart products into the home.
