Anything in the logs that might be useful for us?

2024-04-10 10:19:48.451 DEBUG (MainThread) [aioshelly.block_device.device] host 192.168.1.15: error: DeviceConnectionError(TimeoutError())

Additional information

in the raspberrypi upgrade i loaded a previous snapshot where everything worked. the shelly ip's did not change as well as nothing changed but the board. even the home assistant ip remained the same.

this morning after many hours the shellys connected but the even stranger thing is that all the automations disappeared even though they were written in the automation.yaml file. following a reboot the automations became available again but the shellys will not connect again

all shellys are reachable and usable via http link from browser

What is the IP address of the new PI?

some of your devices doesn't have unicast configured and some are configured to 192.168.1.187:5683, I assume that if you changed the hardware the server received a new IP.

Do you need any other info?

[raptr55]

After quite some time the devices connect to home assistant. After a reboot the problem occurs again.

If the devices connect(even after hours) there’s no problem on network side… I think there’s an issue on homeassistant side.

How can i help in order to solve this problem?

[mattrayner]

I too am seeing this, I have my home assistant running on a dedicated PC and have noticed over the last few days that my shellys have stopped working with connection errors, the only change has been updating home assistant

Could be the same issue as https://github.com/home-assistant/core/issues/115354

See the section Enabling asyncio debug mode at run time (preferred) in https://community.home-assistant.io/t/2024-5-tracking-down-instability-issues-caused-by-integrations/724441

ok something strange happened. right after activating the indicated setting the shelly connected...

look for the device [192.168.1.17]. i enabled the settings at: 2024-05-08 18:06:33.626 CRITICAL (MainThread) [homeassistant.components.profiler] Setting asyncio debug to True

home-assistant_2024-05-08T16-09-54.657Z.log

maybe the timeout time is too tight and when you enable the setting it slows down the system and the response comes before the timeout?
