Zigbee gateway integration

[benanderson_475]

@Bitver, I've had a look at Xiaomi devices and unfortunately all of them have non-standard behavior. It is quite to hard to add them without having an actual device to test. I can provide an example of how to monitor ZigBee messages via a script and implement your own actions based on this.

This would be useful to me, example of how to monitor ZigBee messages via a script, i too am using Xioami devices.

Many Thanks
