Greetings, I only have Nest Protects. Two days ago I decided to try all
the solutions recommended again, reset to default settings, deleting
home, rebooting router (ASUS RT-AS86S) and finally able to add the Nest
Protects without any error messages. ...
I have several Nest Protect, since 2018, and everything was fine until
about a week ago. I tried all the recommended solutions. I deleted the
existing Home and created new Home. Try adding Nest Protects, still
error message P009(0.80). ??
