Two ZigBee devices stop working when both are activated

[Poolitzer]

Hello there. I am not deep into HA, so I hope you people can help me figure out this issue.

I setup two Lidl SilverCrest buttons with the help of Drauboss custom quirks:

Silver Crest ( Lidl) smart Button

I found a Solution: First create a custom quirks direction like described here.: Then create a file there with .py as file extension (name of file doesnt matter) and paste in this code: """Lidl TS004F Smart Button SSBM A1""" from zigpy.profiles import zha from zigpy.quirks import CustomDevice from zigpy.zcl.clusters.general import ( Basic, Groups, Identify, LevelControl, OnOff, Ota, PowerConfiguration, Scenes, Time, ) from zigpy.zcl.clusters.lightlink imp…

They both work just fine when they are activated/connected solely. But when I connect them simultaneously, one of them stops working. Its not the same one, from what I figure its the older. And they don’t fully stop working, sometimes it just takes longer for it to connect to HA I guess? This makes this really hard for me to debug.

Then what I really don’t understand why one button has a firmware number and one don’t, if they are all the same.

I really don’t know where to start debugging this, so I hope someone has an idea.

Cheers.
