I had google nest integration setup from the day one when google had API available. Everything worked fine till I decided to switch to “new way” of integration where you don’t need external link to your HA.
Following direction and watching video I deleted old Google cloud project and made new one. In my HA setup when I click authorize I get “Error 400: invalid_request” but when I go to google cloud console on the OAuth consent screen I put my project into “Testing mode” not “Production mode” it works fine.
Can somebody tell me what am I doing wrong. I use free gmail account not google workplace or GSuite .
