If anyone wants any feedback on the Sensi, I have a decent amount of experience with it. I've used one since about 2016. I will say it's a no frills thermostat, but it just works. It doesn't look out...

I love the ST-55s. No c-wire required...simple setup that is virtually bulletproof imo...batteries will last a LONG time if you use lithium AAs. Does everything you need it to do in a smart...

Sorry this is the ST55 not ST25. Regardless the 55 (white model) can be powered with batteries or C wire.

For everyone else's information, Ecobee 3 Lite does this too. All thermostats in one app, and runs a set schedule. It doesn't try to learn your routine. You can add room units to detect presence and...

They do not charge batteries. They use standard AAs. As I understand it, they draw some power from the non-active system\power share with it to run the wifi. So when you are in AC mode, they power...

Which one of these do you refer to not needing a C wire? I do see they have the option of the power extender but that seems to require 4 wires. I took a look and don't see batteries as an option.
