Nest thermostat help
#1
Moved into the new (old) house, and the previous owners put in a Nest thermostat, but say they never set it up. Now I’m trying to “set it up” and not having luck. I have downloaded both the Google Home app and the Nest app and laboriously entered my router’s password into the thermostat. (!). And it seems to see the network and connect.

In either app, I can “add a device” and choose the thermostat, but I run into roadblocks, like: get a seven digit secret code from the thermostat. (Why? Dunno - that’s just what it says to do next). When I try to, it spins its little circle and eventually says something went wrong getting the code - try again later. Which is what it also says later. Also, I’ve seen several references to the “service”, which looks like it costs $8/mo. (To run my thermostat?). Google troubleshooting is about as helpful as usual: “try moving your router”. :RollingEyesSmiley5:

The furnace is also frequently cycling on/off ~14 min, then off for 4-6 min. This old house doesn’t have a lot of insulation, but the on/off cycling seems excessive.

I’m not looking to do anything fancy - set back temp at night, up during waking hours. Various Google sources suggest if I do this manually enough times, it will learn our pattern. Will it?

So far, I don’t see what the fuss is all about - not worth the repeated data entry, and certainly not worth $8 a month. The previous owner also left behind a Nest smoke detector, which takes 6 (!) lithium AA batteries, and I presume I need to set that up too. So it can send me a text message when my house is on fire, I guess.

Any tips?

Can’t give you specific answer. But maybe this posting from google nest group might help.

Honestly it might be better to go out and buy a new cheap thermostat and replace the nest. The cycling thing is not. Normal behavior. Might indicate a broken unit and is not safe imho.

Sorry I am not familiar with Nest thermostat, I used Ecobee.

Is there a factory reset menu on the thermostats? I would try that and then try to start over.

Also, years ago I read that Nest had an internal lithium battery and that goes bad occasionally leaving the thermostat useless. This is a real problem for people with vacation homes that are unoccupied for long times. I chose Ecobee for that reason. No battery to go bad. I am not sure if newer models of Nest have this issue or not.

Good luck.

“ frequently cycling on/off ~14 min, then off for 4-6 min. “

The first several minutes of a heating system coming on doesn’t provide much meaningful warming.

I own a Nest and have no idea what the $8 service is.

Do a factory reset and try again. If you still have trouble try contacting Nest support.

I had my Nest thermostat replaced under warranty due to a failed battery which wasn't too different from what you're experiencing. OH! Take it off the wall and plug it in for a bit. It'll charge the battery. This might be necessary if the heating system was off for a while. I'd do this after the factory reset and before reattempting to establish connection.

Connecting to the network is peak power usage for the little device. Its possible that its failing because its under charged.

Plug it in where? does it have a charging port?
