Success with Sonoff zigbee bridge and zigbee binding

Quick question; you guys using the Tasmota-flashed Sonoff Zigbee Bridge - do any of you have a working example controlling an RGB light through MQTT (I am interested in the .things definition) ??
I raised the question seperately here: Issue with Sonoff Zigbee Bridge with Tasmota - controlling RGB strip through MQTT - but guess that I might get easier success asking in this thread ?
