Open window switch with separate Homebridge instances causes problem with automations 
I have noticed that ever since I moved to two Homebridge instances (149 limit reached)  the window open switch does not work as expected. [Hb wiki](https://github.com/oznu/homebridge-config-ui-x/wiki/Homebridge-Service-Command#multiple-instances) 

I use Zigbee window sensors (with deconz) in the first instance to trigger HomeKit automations to temporarily disable heating through the Fritz platform (2nd instance) window open switch. Previously working very well.

It is possible to manually trigger window open switch (see log) but HomeKit automations do not work. 
The home app shows both window contacts as well as open window switch correctly. I am not sure where I can find any status about it to trace errors or bugs.

I am using the latest Homebridge Fritz platform plugin and nodejs lts
