433.92 MHz 32-bit protocol e.g. Nexa Remote Switch and rpi_rf

Configuration
1

I just bought these Nexa Remote Switches https://www.clasohlson.com/uk/Nexa-Remote-Switch-Set-3-pack/18-2650. The switches are self-learning and can be paired with up to three different remotes.

As I understand, it’s possible to pair a switch by sending a code using the rpi_rf platform in Home Assistant. Problem is that the protocol for these switches is 32-bit and not 24-bit that is common for 433 MHz RF.

How do I set these up using Home Assisant? Do I use the rpi_rf platform? What’s format should the codes have?

Did you solve this? Thanks

I am using the Nexa switches and have reverted to the Broadlink RF sender instead. Working perfectly well.

I managed to sniff my codes (not the protocol nor pulselength) with this (receiveRF433Ctrl.py). The codes come in the form of “1799812476”. I have the same plug as @str33, but in EU-version.

However, I do not know how to get further and in to HASS. @eschumann, could you please evolve your use of Broadlink RF sender?

I use either RF link or pilight to control mine.

Not yet. I will try using pilight.

Solved it now! I skiped hass.io and installed Rasbian on the Raspberry Pi 3. Then pilight. Started pilight-receive and got the codes! Then installed Home Assistant and the pilight plugin. Configures Home Assistant and it worked without problems.

pilight:
  host: XXX.XXX.XXX.XXX
  port: 5000

switch:
  - platform: pilight
    switches:
      XXX_Lamp:
        on_code:
          protocol: kaku_switch             
          id: xxxxxxxx
          unit: 0
          'on': 1
        off_code:
          protocol: kaku_switch             
          id: xxxxxxxx
          unit: 0
          'off': 1

I will try this right away!
EDIT: Still not getting signal… :confused:

How does your config.jason in etc/pilight/ looks like? Thanks
