Hi!

This has happened to me with 2 different modules I originally had a K4412CM2 connected to the Legrand gateway and working properly.

After resetting the connection and moving it to Zigbee the switch has stopped working. The light it always on and it doesn’t matter which button I press it won’t turn off. I know the buttons work because the Led on when off is enabled, so when I press to turn off the led of the switch turns on and so on.

I though this one may have been broken so I ordered a new one a K4411C, the same happened. It was working properly with the Legrand gateway, but as soon as it connected to the zigbee network it stopped turning off the light.

I’ve tried resetting them both (for 20 secs or more) and connecting them back to the Legrand gateway, but they’re still stuck and will always keep the light on. As soon as I power up the grid the light is turned on, i don’t need to press it.

I’m doubting they’re both broken, it seems to be a SW thing. Also the full reset does not seem to fully reset the switch, as the Led when Off functionality is still configured after doing this.

Is there any other way of fully resetting them? Is there something preventing them from working with zigbee?

Hello,

As said previosuly, you should contact directly your local customer support concerning this problem. As I’m not linked to them I don’t have any visibility over a potential problem

<p>This is pretty awful quality checks by Legrand/Bticino as I had the similar situation just yesterday. Mine is k4411c I order from sosilux.eu. It was working fine on/off mode manually with other basic philips led bulbs and aqara t2 bulbs.<br />Then I started HA + Zigbee2MQTT devbranch and added k441cc. Oh boy, that was a big mistake. Initially I could turn off/on on HA panel. But then it bloody broke. Now, no resetting for no matter how long works, switching off circuit braker for 10 hours did not help either — the lights are always ON, bloody hell, Legrand, how is this “mechanical” issue? Obviously there is some big issue with your firmware!  </p>
