Legrand devices disconnect after few second

[itobald]

Hi,

I have an issue with my Legrand device 067775/741811.
They seem to pair well but left the network after few seconds.

Do you have any idea of the issue ?

Zibee2Mqtt 1.37.1 with Home Assistant.

I'm experiencing the same issue with Legrand 412171 with Zibee2Mqtt 1.38.1 with OH4. Some of same device are correctly joined but some other not. My idea is probably their fw version are different but obviously I cannot upgrade the ones not joined.
Any idea is appreciated.

I have same problem.
I have downgraded to version 1.34.0, pairing the devices and upgraded to 1.40.1.
I have tested with most Legrand devices, all to the latest firmware and it is same problem.

So you've upgraded Legrand devices to the latest firmware without using Z2M ? If yes how ?
As reported, I've some of them joined to Z2M, so I used Z2M to upgrade w/o issues.
For other Z2M join is not working and so cannot try to do the firmware upgrade.

Firmware upgrade are does with Z2M or Legrand getaway.
If i downgrade Z2M, pairing is possible and after upgrade to latest version, device is working (and upgraded if necessary)
