Error DataUpdateCoordinator.async_refresh

Describe the bug Hey Aohzan

Sometimes when I try to turn on/off my switch in my HA, My IPX800v4 dosen't return states to my HA.

The consequences of that is that my switches states on my IPX800v4 look "ON" and the switches on my HA look "OFF"

After that I have this error logs :
