Like many posts seen here, my nest thermostat worked normally for many months, and then all of a sudden I noticed it lost its wifi connection, a week later it basically broke saying it was always on low power and cannot charge or function. I take it off the base and charged it for hours, and after putting it back on it immediately says again the battery is low and cannot function. This is frustrating and a huge liability as if we were not home when it broke and the house went below freezing we would have severe issues.
It worked fine for many months now, after taking it off base, I used volt meter to see that there was power to C, so it's not that, it has always had power to C wire.
I'm also concerned because power companies often give out rebates for these newer devices because they enable some better efficiency and programs they monitor. However given that these products are unreliable, I am concerned about utility companies and governments offering rebates for them.
