homebridge-z2m never reads occupancy sensor state
Hi there,

Love the plugin.  Recently I picked up a Linkind ZS1100400-IN-V1A02 PIR motion sensor, which is supported by zigbee2mqtt ([see here](https://www.zigbee2mqtt.io/devices/ZS1100400-IN-V1A02.html#linkind-zs1100400-in-v1a02)).  Sure enough, in the zigbee2mqtt console, I see the device on the network, and I can see that it changes the "occupancy" state from false to true and vice versa when it picks up motion.

Homebridge-z2m adds the device and I see it in the Home app.  Using the latest homebridge-z2m as of the time of this post.

However, the Home app never picks up on the occupancy sensor state change.  There is never any corresponding log in the Homebridge console that would indicate that homebridge-z2m also picked up on the occupancy state change.  However, I can see the state change in zigbee2mqtt.

Other devices connected via zigbee2mqtt work just fine through homebridge-z2m.... but for some reason, its like homebridge-z2m doesnt know what to look for in the case of an occupancy sensor.

What can I provide, here?  I don't seem to have any logs on the homebridge-z2m side because nothing ever happens.
