RFXtrx sunscreen (cover) detected as binary sensor

Hi,

Switching from Domoticz to HA, and the last thind to migrate are all off my 433MHz devices. And by searching the forum I now managed to get almost all working.

The final thing I was having trouble to detect in HA was my sunscreen. Tried:

cover:
  - platform: rfxtrx
    automatic_add: true

without any luck. But then I tried:

binary_sensor:
  platform: rfxtrx
  automatic_add: true

and there it was.

So. Is this a bug, or have I misunderstood something?

Found a lot of threads here on the forum not able to get covers working. And all of them are trying to discover them as cover. But nowhere I found that this could be the solution.
