Niko 4gang zigbee switch not being found in HA

Hi Guys,

Currently i’m setting up an POC to be sure that i’ll be using HA in my new house as smart house system.
My shutters work, i added smart light bulbs (INNR).
But 1 thing i seem to fail to get working.

My wife would love some classic visual switches (for us, Belgians that means switches from the brand “Niko”).
So they sell niko zigbee switches, but when i put this into pairing mode, i can’t find them with my zigbee sonoff stick.

My zigbee stick seems to work, because my inrr smart lights that use zigbee work.
The niko switch seem to work, because i’m able to pair it with an innr light bulb directly.

But i seem to fail to get the switch to work with HA.

Does anyone have any idea?

Kind regards,

Some of them are supported in Z2M at least: Zigbee2MQTT
