Nest Low Voltage plus Error Code E261

Jaysanity — Tue, 22 Mar 2022 19:08:59 GMT

Hi Everyone,

I have the Nest Thermostat (Sand). I am getting low voltage 3.12 and I hear the recommended is 3.6+. What will happen if this keeps going at this rate? What problems will I notice in a few days? Everything is hooked up from the C-wire. Not sure what to do as I keep getting the Error code 261. Help!!!!

I haven't gotten the error code or low voltage code. But mine won't update and I read that your battery has to be at least 3.7 volts to update. How do you get that out of two 1.5 volt batteries? Mine is also connected to C-wire. Again, I'm getting not voltage errors like you or low battery errors, it just won't update. And customer service is ZERO help. They just send me nice replies that don't answer the question.
