How does Nexa switches communicate?

Hardware Home Automation

I found some cheap wall switches in Nexa Wallmounter Transmitter, and from this doc it seems that they work with Tellstick DUO: https://github.com/openhab/openhab/wiki/Tellstick-Binding
Here is a video of the switches: https://www.youtube.com/watch?v=U83dZwQVg4A

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.

Thanks.

Hi

I am using RFXtrx433E to receive commands from Nexa Transmitters.

RFXtrx433E works with almost all 433 wall switches.
