How does Nexa switches communicate?

I found some cheap wall switches in Nexa Wallmounter Transmitter, and from this doc it seems that they work with Tellstick DUO:
Here is a video of the switches:

My questions are:

  • What kind of communication does Tellstick use? And can i use another gateway for Nexa switches?
  • Are there other kind of wall switches that can be taped directly on the wall like Nexa?

Hope somebody has experience with the above.



I am using RFXtrx433E to receive commands from Nexa Transmitters.

RFXtrx433E works with almost all 433 wall switches.
