Thanks for posting here in the Community. To confirm, are they all connected on the same Wifi network? How far is the distance of each device? How many home structures do you have? Try restarting your Wifi network and Nest devices. Let us know how it goes.
I'm dropping by to ensure that everything is covered here. How's it going with your Nest Doorbell? We would appreciate it if you could share the information I’m asking above. Also, were you able to perform the steps I’m suggesting? We'd be glad to hear from you.
Just one quick final check in here since activity has slowed down. We'll be locking the thread in the next 24 hours, but if you still need help, we would be happy to keep it open. If there's more we can do, just let us know.
