Nest Protect P009(0.80) error

[vivlund]

I've had 2 Nest Protects connected on the network for years, but as of yesterday, neither of them will connect to the network, and they both went offline at the same time, possibly after some update to their software or the iOS app. Same router, same router settings. I've tried the troubleshooting steps and made a new home on the app, but nothing works. Can anyone help me?

Hello to all the community.
I'm based in France and I had the exact same problem as all of you.

Seeing nothing coming, I called Google Support directly and had a human being who handled the matter as follows:
He had replaced free of charge one of my detectors (which are 7 years old) for a more recent model/firmware (it a 2020 model).
To be able to make everything work again with my other detectors, I had to declare it as "master" (I had deleted all the others) and then I was able to add the other detectors by pressing this new  as "Master".
Suddenly everything works perfectly again.
On the other hand, it is necessary to declare the sensor exchanged as master (or 1st) because the detectors which have the problem are not capable of playing this role.

I don't know if in the US, this could work, but since Google cannot correct its Bug, the solution they offered me works and allowed me to keep my other detectors.

Hope this helps, keep me posted.
Good luck.

Thanks @Clemlar!

Confirming that a fix for this behavior did arrive with Nest app version 5.74 on iOS. I recommend iOS users experiencing this error to update their Nest app to the latest version. The team is continuing to work on a fix for Android users, I will keep you all updated as I hear more.

Thank you,
Kelan
