Thermostat Won't Auto Reconnect After Wifi/Power Outage

[PacoTaco]

Same issue as reported in the thread below. 

Thermostat is technically online because it is reporting data back to Google. 

However it shows as Offline in the app and won't let you control it remotely -- one of, if not THE main reason for buying the Nest. 

Why are the thermostats not resilient against wifi/power outages in 2025?!  The cameras don't have this issue.

Is this a new install or has it been working and now it isn't?

Post a picture of the original thermostat's wiring if you have it and one of how you have the Nest baseplate wired.

It was installed in Dec 2024.

I can't show a picture/diagram as it is at a remote property that I only visit once per quarter -- which is why I want a more consistent, resilient solution.

It works fine as long as wifi/power is consistent and doesn't drop for an extended period of time.

Unfortunately these outages are more common for that area -- I don't have that issue with the Nest thermostats installed at my primary residence. 

I've even gone as far as to set my router up to auto reboot daily, but unfortunately the timeout/disconnect is less than 24 hours.

It's hard to troubleshoot a remote system like this.

The problem might be that your WiFi isn't powering up before the thermostat does and the thermostat is seeing that as no available WiFI. Try installing a UPS (aka battery backup) to your network equipment so the wifi never drops out.

[PacoTaco]

I already have a battery backup installed, so that's not the issue. 

The issue is a bug in the thermostat software and it's ability to reconnect.

I have Google cameras that have no issues with reconnecting after outages.
