Reliable and works well
I've had three Sensi Smart thermostats installed for over five months and they work well. I've noticed a reduction in my electricity costs now that I can remotely control them and set a program. My only issue is that the program does not allow for time zones outside the US and Canada. I use the devices in the UAE and have to adjust the program 8hrs ahead and adjust for daylight saving manually. It would be great if additional global time zones could be included in future updates. Just like the other manufacturers have done.
