Has anyone paired Vallhorn motion sensor to Sonoff Zigbee Bridge?

I’ve just ordered an Ikea Vallhorn motion sensor, with the intention of pairing it with my Sonoff Zigbee Bridge (flashed with Tasmota). I want to use it to trigger lighting in the hallway.
I was wondering whether anyone had any hints re. pairing/using it with the Sonoff Zigbee Bridge?

What coordinator software are you using?

If I understand you correctly, I believe that I’m using Zigbee2Tasmota (with MQTT to interact with HA)

Then this is a good place to look for immediate compatibility.

If your device is not there, this will give you more info:
Zigbee - Tasmota.

Thanks for the links.The Vallhorn isn’t on the compatibility list so I’ll have to cross my fingers and hope that I can pair it when it arrives…

I can confirm that the Vallhorn paired first time with the Sonoff Zigbee Bridge (running Tasmota). 4 button presses on the top Vallhorn button was enough, after I’d put the Bridge into “Permit Join” mode.
