The worst service and thermostat ever! After a year of using the thermostat, it no longer connects to wifi and is offline all the time.They sent me a replacement refurbished and damaged- does not connect to heat link and now they are not responding to email and on the phone they lie that they will connect me with senior representative and then they say that's not possibile. I was patient for 2.5 weeks but tomorrow the matter is reported to the CCPC.
