Adding DW2 RF Door Sensor

Hi,

I have just added a DW2 RF door sensor with a Sonoff Bridge but I can’t see the door sensor. I can see the Bridge but not the sensor.

I am using AlexxIT/ SonoffLAN for the rest of my Sonoff devices and have the Nabu cloud subscription. How do I add it to my home assistant?

Thanks

I just bought the same device.
I already have an Rfxcom reciever and a number of other 433 MHz devices, among wich a couple of door switches. I didn’t buy a Sonoff bridge because I assumed the Rfxcom would be able to handle it.
But it doesn’t see it.
I notice in Rxcfom configuration that all protocols were unchecked. Is this correct? All other 433 devices still work like a charm.
