Disable specific chracteristics of a device
Hi,

I'm using a motion detection device HmIP-SMI and yes it works fine.

But it is discovered/recognized as 2 single accessories in HomeKit, as Motion Detector and as Light Sensor (similar to #141).
I do not need the Light Sensor in HomeKit so it would be great if it can be disabled.
The only difference I see is in "aid" and "iid".

**Motion Sensor:**	
Motion Detected	0
Status Tampered	0
Status Low Battery	0
Manufacturer	EQ-3
Model	MOTIONDETECTOR_TRANSCEIVER
Name	BWM XXXXX
Serial Number	HmIP-RF.00011122233344:1

Homebridge Instance IP	192.168.1.1
Homebridge Instance Port	51111
Homebridge Instance Username	AB:CC:DD:EE:FF:11
**_aid	60
iid	14_**


**Light Sensor:**
