Trouble discovering Legrand with Netatmo switches in ZHA

Configuration Zigbee
,
5

My Conbee II was on channel 25 while Legrand devices seem to only operate on channel 11.

In order to change it, for the Conbee II:

  1. Install the deCONZ app on the device connected to the Conbee II (in my case: my raspberry Pi)
  2. Launch the deCONZ app
    a. If you’re running a headless version of the operating system (one without GUI), you’ll need to SSH with X forwarding enabled and launch the app from the SSH session. This should open the GUI on the device you’re using to connect to the RPi.
  3. From there, launch the Phoscon web app
  4. Change the channel in the settings
  5. Quit the apps

The deCONZ app takes precedence over Home Assistant and takes control of the key. While it’s running, you won’t be able to control your Zigbee devices on HA. It releases its control once you close it though.

After changing the Zigbee channel, you can discover the Legrand wireless switches in HA.

In order to successfully pair them, I had to:

  1. Start the discovery process
  2. Press and release the reset button on the device. If it only blinks green twice and red once, you’ll need to press the reset button longer until you see a red blink. Now you can release it.
  3. The switch LED will blink green multiple times
  4. Regularly press the bottom button to keep the switch awake (not sure if necessary)
  5. The switch will appear in HA and the LED will blink red once. At this stage, the device is not fully paired.
  6. Wait a minute (really, wait some time)
  7. Start the discovery process again in ZHA
  8. Press the reset button once and release it
  9. The switch LED will blink green multiple times
  10. Regularly press the bottom button to keep the switch awake (not sure if necessary)
  11. The switch will appear in HA and the LED will blink purple once.

Your wireless switch is fully paired and operational. It sends events when you press the buttons. It also detects long presses and sends an event at the beginning and another when you release it.

I’ve successfully paired 6 single wireless wall switches (600083), 2 double wall wireless switches (600088) and a home/away switch (600085).
