Nest 3rd gen W5 error not connecting to WiFi

[WiGo]

Hello,

I have issue with connecting to WiFi, where thermostat showing W5 error, shuting down...gone over troubleshooting, charging it...nothing works.

I bought it on Amazon.de in Fabruary 2023. Everything worked fine, using Open Therm protocol on my Combi Viessmann with HeatLink connected, Wifi connected...just perfect temperature in my house, until few weeks ago, end of September, I notice that device is showing W5 error and shuting down as soon as I try to make some setup.

Got in contact with support and after 10 days of going back and forth i received an email from google support, C/P it here;

Thanks for reaching out to the Google Nest Customer Care Team.

Finaly, I have received package back from Service Department and was I suprised!

I have sent Nest display without heatlink like instructed by support. 

Service dept. returned another heatlink but not replacement display so now I have 2 Heatlinks and no display to control my heating 😞

Thank you for sharing this. I am sorry to hear this and I'll look into your case right away. In the meantime, please use the manual mode from the installed Heat Link by pressing the button on it to turn your system on and off. 

[WiGo]

Thanks. I’m pressing the button😲 Twice in the morning and twice in the afternoon 😉
