running the latest version of core-2021.6.1 and supervisor-2021.05.4 on a RPi4.
I have installed the Shelly add-on via hacs.
From time to time, i have the problem that my Shellys (3 of type, 2.5 for my roller shutters, 6 of type Plug S) become unresponsive.
I do not see any entries in the HA logfiles.
All devices have a static IP address configured via my Fritrz!Box.
I reloaded the Integration, also restrated HA - no effect.
All Shellys have latest firmware installed. Also rebooted the Shellys - no effect.
Also unplugged one of the Shelly and re-plugged - no effect.
Anyone has any idea what is wrong here?
Searched in the forums and by G*** but not really found s.th. which helps.
In Github of the integration, i see several similar, but not what i am encountering.
Thanks for your help in advance,
