Ubisys s1-r is on though automation switched it off or shows wrong state

Hi there,

I sometimes have the problem, that my Ubisys S1-R ignore when an automation should switch them on / off. The automation then says the relais has been switched on or off but it didn’t happen

I even had now 3 times the issue, that the Z2M Expose page showed the device is “on” but it was off. So I had to turn it “off” and then “on” again.

Is this a known issue or is something wrong here?
I have latest version z2m and HA installed.
The problem exists since ~ 6 months now
