Profalux Cover not usable

[nakedfoot]

What happened?

Hello,

Got some Profalux Zigbee covers,
They where never connected to my zigbee installation (only used with their natives remotes).

I'm using a proxmox with a zibee2mqqt lxc (v2.0.0, beta chanel, working great for me)
SonOff ZdongleE flashed with 7.4 firmware

When in put the cover in pairing mode, zigbee2mqtt detects the remote and the cover,
But in a "not supported" way.

i got this message in notification (light blue background) :

"zh:controller:device: Device '0x20918a0000013991' is only compliant to revision 'pre-21' of the ZigBee specification (current revision: 23)."

Seems that the cover is in the herdsmann-converters and i saw some post on forums where people talk about working cover with zigbee2mqtt.

FYI, when i restart zignee2mqtt.service, the cover move (up and down for 1 or 2 sec), so it is really connected to my installation.

Any clues ?
I can post more info if needed.

Thx.

PS : sorry for my english, not my natural language.
