3rd Gen WiFi Connectivity and Dead Screen

Vetter91 — Sat, 06 May 2023 05:17:24 GMT

Over the past few weeks the 3 Gen Nest thermostat has repeatedly gone offline. Sometimes it will reconnect, but now I mostly have to restart. Up to to five or six episodes dailey Tried all of the tips and troubleshooting. WiFi setup is unchanged. This unit had been 100% reliable up to now. Very frustrating.

Recent threads describing no connectivity and dead screen combined reflect my experience.

@Vetter91

How long has it been installed?

How is it wired? Post a picture of its wiring here

Does it have a C wire installed?

Professionally installed in 2017. C wire is installed. All efforts to resolve via thermostat reset, router reset, hvac reset, troubleshooting wiring, etc. have failed. Very frustrated with this situation. Photo attached.

Hello folks,

I wanted to stop by and see how I could help.

Thank you for all your input, @Patrick_Caezza.

@Vetter91, I'm sorry to hear that your thermostat keeps going offline, and I appreciate all the steps you've taken. I'd love to know more about this.

To isolate:

Are you getting or receiving any power-related reports?
Do you see any message codes in its settings?
Could you please gather the power reading in the Technical Info settings?

I'll look forward to your response.

Regards,
Mark

@Markjosephp regarding your questions, there are no power related reports, or message codes. I have attached a photo of the powere readings from the technical setiings. Note, typically, I find the stat completely powered off and unresponsive to repeated presses to wake. After numerous attempts, it may wake.

Hi Vetter91,

I'm sorry for the late response. I see no power concerns with your thermostat's power readouts. Check its Signal strength in the Technical Info > Network. Then, in the span of 4 weeks, did you encounter the same issues? How's it? Were there any instances that it had withdrawn its power?

Regards,

Mark
