Need some guidance on the wildly involved process of setting up connection to Nest thermostat. I got through most of it, right down to the last step of linking to the google account. I got the buttons to allow it to see data about my home and selecting “thermostat”…then it wen sideways…got an error different than was was in the help doc, I didn’t capture it but it was referencing developer access of some type not being available. When running through it again I enter the project ID, the device ID then I get a small box about configuration flow already in progress. How do I get past this?
I’ve got this same issue. After selecting my google account for the 2nd time I got redirected to a blank screen. I didn’t have time to troubleshoot so I left the setup process and came back to it later and now have this issue. I found this thread saying similar but it did not fix my issue. It might fix your issue however if you wanted to give that a try. Nest integration configuration flow permanently stuck - Configuration - Home Assistant Community
