Nest Thermostat Setup keeps asking to replace batteries

[Maverick13]

Hi all. Trying to install a Google Nest thermostat. I’ve installed a couple of them so I’m aware of the basic wiring and process. I have the thermostat installed on the plate and all the wires are in the terminals. I go to set it up on the google home app and it keeps asking me to replace the batteries. I’ve replaced the batteries a few times and it continues to ask me to replace the batteries in order to complete the set up

I’ve had the same problem with my 2nd Gen battery-powered nest smoke detector. I’ve since replaced the lithium rechargeable batteries twice, then replaced the whole unit. It works but now it won’t sync with the hard-wired nests in my house (so it doesn’t show up as an additional unit like before.) I installed the system myself about 5 years ago without problems. What gives?

I should clarify that I did use the proper replacement batteries (Energizer Ultimate Lithium AA (L91) batteries) for my battery-operated smoke detector.

Hi everyone,

Thanks for reaching out and apologies for the late response.

@Maverick13, I'm sorry to hear the issue is still persisting even after replacing the batteries. To isolate:

• Make sure to use the recommended Energizer AAA 1.5 V Alkaline Battery. 
• What are the wiring configurations on your thermostat?
• Are you getting any message codes or wiring report on your Nest Thermostat device?

@mmm062, I appreciate you've tried to find a fix by replacing a required battery specification for Nest Protect. Let's find out more about what happened.

• Are you having an issue connecting it to the Nest App?
• What's the status of your Nest Protect? Press the button at the center to check.

Keep us posted on how it goes.

Thanks,

Mark

The problem is actually with my battery-operated smoke detector which is not connecting with my other hard-wired Nest smoke/carbon monoxide protectors. It should be noted that these smoke detectors were all purchased at the same time and were functioning correctly for 5 years. I’ve replaced the battery-operated (not hard-wired) when it seemed that the batteries appeared to be dying. This new unit was purchased with all the others as a spare.

Hi mmm062, 

Thanks for getting back to us. Could you please move the devices closer to each other and to your Wi-Fi router, then reset the devices? Once done, start setting up your devices Here's a guide: Set up Nest Protect with the app.

Let me know how it goes.

Thanks,

Jennifer
