Support Dw2-RF contact sensor as garage door sensor
Currently emulating garage door using multichannel sonoff and it works great, thank you. I also have a DW2-RF contact sensor to sense of garage is open or closed and it shows up in the plug-in/Homekit but cannot be used as sensor for the emulated garage (currently supports Wi-Fi or zigbee contact sensor). 

Could this support be added? Sensor shows up in the plug-in fine and works well as an independent HomeKit sensor.
