Shelly Plus Smoke auth expired and needs reconfig

Configuration
1

Hi, this is my first post and don’t know where to go to. I have Shelly devices (gen1,2 and 3) including ten Plus Smoke which I integrated a week ago. All devices have passwords and are integrated. Specifically the Plus Smoke devices cause HA notifications „Integration required reconfiguration“. The settings page shows that a repair is needed due to auth expired. There is nothing in the HA protocol about this issue.

I need to reintegrate with the password.

This happened multiple times and interestingly only to a few devices. Some are good since they were added. Others I have to reintegrate almost daily.

WiFi coverage is good to all devices. All are on v1.4.4 uptodate. Is there anything I should try for more details?

If you didn’t change the password, restarting HA should fix the problem.

Hi, thanks. Reboot helped to get rid of the messages. But over time they come back. I’ll gather debug logs from Shelly and see if they show what’s happening.

I gathered logs and have seen a bunch of 401 response codes from the shelly device. I don’t know exactly what’s happening. Assume ha integration asks for multiple data points and the shelly device changes nonce too many times. Also, after boot of the shelly device, it connects with ws way before it got time from an sntp server. I assume this causes the nonce changes. I tried a local sntp server at home but it only seemed to mitigate the issue by a little bit.
