Unstable Status "Unavailable" - Shelly UniPlus - starting with HA 2024.7.0 Update

Hi everybody :slight_smile: ,

since the HA update to 2024.7.0 I am experiencing different behaviour in both of my Shelly PlusUni devices. This results in problems with my automations.
Starting with the HA upgrade, the entities of the devices show in most of the times “unavailable”. Only in the moment the device reports its status data, the HA status switches shortly to the reported value but instantly switches back to “unavailable” again.
Before the HA update, the entity status was kept stable until the entity itself changed its status. See Screenshot - behaviour after the update is in red rectangle.

Can anybody confirm having this behavour as well?
Or do you have a hint, what to change to set it back to the behaviour I had before?

  • I am using HA 2024.7.0 since 3.7.24
  • HA Installation is in a docker container on a x86-64 device.
  • Shelly Firmware (v1.3.3) did not change in this time period.
  • HA binding of Shelly PlusUni as described in [Shelly - Home Assistant] - " Shelly device configuration (generation 2 and 3)" - Outbound WebSocket

Thanks an regards,

In the log I see error messages like this:

Similar issue reported here. Looks like a fix is planned.

Should be fixed in 2024.7.1

Thanks für the link!
I upgraded to 2024.7.1 and the error is gone :+1:
Thanks to the HA team for the quick reaction!
