Disconnected HMIP-FSM generates warning message

[smhex]

It's for sure not a normal use case, however I noticed a warning when my disconnected HMIP-FSM receives some update from the cloud service. In my scenario the HMIP-FSM is triggered by a HMI-SMI55-2. If I switch the HMIP-FSM ON/OFF via Homematic App everything works as expected (except the fact that nothing happens).

[6/18/2022, 9:44:39 PM] [homebridge-homematicip] This plugin generated a warning from the characteristic 'On': characteristic was supplied illegal value: null! Home App will reject null for Apple defined characteristics. See https://homebridge.io/w/JtMGR for more info.

Maybe in this rare case the message response looks different...

I will take a look on it myself. This issue is just for documentation 😀

I could not reproduce this issue hence I will close it.

Found the cause in HmIPSwitchMeasuring.ts:Line 93:

if (switchMeasuringChannel.on !== this.on) {

needs an additional null check

Created PR #390 with bugfix

Hi @marcsowen , is this PR worth to create a 1.0.1 version of the plug-in? Thanks for reviewing it.

[marcsowen]

Thanks! Sure, I will release it tomorrow.
