After deleting my nest thermostat and most manager… I reinstalled everything and when I go to login nest credentials it will allow me to put in the info and ciick accept. After that. Nothing happens
It’s been a while but I think you need to go into the Nest app, find the notifications section and authorise (white list) Nest manager… should be a message there asking for permissions.
If you check out the NST Manager thread, you can find out they are out of tokens. You will need to create a Nest Developer Account and create your own token. It is in the wiki which you can find at the top of that thread.
