Prevent Osram Switch Mini to control Osram Smart Plugs via broadcast messages

[Vermatic]

I am currently evaluating different home automation and Zigbee solutions.

I am using a TI CC2531 USB and the following ZigBee devices:

• Osram Smart+ switch mini - https://www.zigbee2mqtt.io/devices/AC0251100NJ_AC0251700NJ.html
• Osram Smart+ plug - https://www.zigbee2mqtt.io/devices/AB3257001NJ.html

Currently I have an evaluation setup with node-red and I'm trying to use node-red-contrib-zigbee.

I now ran into the same problem that me and several other people have already encountered in the past: the Switch mini device will automatically control surrounding Plugs using broadcast commands autonomously, ie. without further intervention of the ZigeBee gateway.

I guess the problem is well understood and has been solved for other projects already, for example zigbee2mqtt. There is a well documented bug report here: Koenkk/zigbee2mqtt#962 The bug report mentions the commit that fixes the behaviour: Koenkk/zigbee-herdsman-converters@7756df8

When I evaluated node-red + zigbee2mqtt + node-red-contrib-zigbee2mqtt I ran in the same problem as described in the bug report and I can confirm that after updating zigbee2mqtt manually in my setup the problem was gone.

Now that I have reset all my ZigBee devices and evaluate node-red-contrib-zigbee, the problem is back of course.

I have first paired the Switch mini, then I paired the Plugs and immediately pressing buttons on the Switch mini controls all plugs nearby.

I must admit that I have no idea how the problem was actually fixed in zigbee2mqtt and how this fix can be ported to node-red-contrib-zigbee.

So my request would be: can this fix to prevent Osram Switch Mini to control Osram Smart Plug via broadcast message be pulled into node-red-contrib-zigbee?
