Solved! Nest Protect due to error P009 (0.80). Requires port 11095.

This one was driving me insane.

I'd tried all the suggestions of creating a new home, using 2.4Ghz, making sure no other Nest products etc. etc.

Finally, I started monitoring my firewall and saw connection attempts on port 11095 from the Protect being blocked.

Added a rule to allow it and bingo! Added to the Nest app and got the verbal "Connected" message.
