So, i’m got through the whole setup, SSL working, Google actions app setup etc, using these docs:
I’m now on the last step of adding the “device” to Google home, I see it “[test] Smart Home Control”, when i click to add it, it takes me to an oauth2. page, then redirects back to the Home app, briefly at the bottom it flashes up and says:
“Linking your [test] smart home control account”
Then at the bottom it says “Couldn’t update the setting. Please check your connection”
