I have had a Nest E Thermostat for 2-3 years now. Only a few months into using it, I kept getting a low battery message from it, it disconnects from wifi and can't be controlled from a phone or PC in the Nest app when this happens.
I contacted Google support about this on three different occasions, they just told me to remove the thermostat and charge it with a phone charger when this happens. The battery gets low because I do not have a 5th wire, the C wire, in my thermostat wiring. That wire provides constant electricity that would allow the battery to stay charged, most homes have them these days but older ones like mine do not have that wire.
The Nest E sometimes works without that wire, but in my case (and for many others I've read about) people keep having the low battery issue.
I have been recharging mine with the phone charger as needed, but it's happening often enough that it's a real bother.
I was considering to have an electrician come here and install a C wire, but that can be expensive. Then I saw today that there are C wire adapter kits sold on Amazon... and then I saw the Nest Power Connector that's sold by Google.
According to other Nest users, beginning in mid 2021 people started receiving emails offering them a free Nest Power Connector to help their thermostats run correctly. Unfortunately I didn't receive one, but I could definitely use one.
Does anyone know if it's still possible to get the offer to receive a free one?
