Hi I also see this a lot.

I think its due to networks issues not the integration. I have 300+ shelly devices and a unifi network. Unifi are telling me that I have too much multicast packets from the Shelly devices and it causes disconnects of the wifi devices.

I would be really interested to hear further information on this as its killing me with this lighting system not working.

I have been suffering from the same issue. I have 7 Shelly 1's configured in Home Assistant, they will drop connection from time to time giving the error DeviceConnectionTimeoutError(TimeoutError()).

Network stability as mentioned by @pwcutajar in his comment should not be the issue, nothing in my environment has changed. The issue only started after updating my Home Assistant 2024.9 and has been prevalent since. I'm currently on Home Assistant 2024.12.5.

The following open issues seem to be experiencing the same problems and errors: #123585 #126152 #123585. Loads of log files and screenshots provided in all the open issues.

So I can also rule out network problems in my case. On the one hand, the UniFi monitoring was completely normal during this time and no other WLAN devices had any dropouts.

What can I do to contribute to the solution? Would a debug log help? What other information is needed? What else can be done to localize the error?
