Sengled lights - compatability with Homey

I have searched the forums but I cant find any reference to the Sengled lights and compatibility with Homey. Esp. the bulbs with the built in speakers. Does anyone have any experience to share ?

There is no app using that name so I do not think its supported.

I accept this challenge! I can code, rusty but still on occasion. On a mission, hopefully I can use existing zigbee implementations as a template

Sengled now has an officially supported app, you can find it here: Sengled App voor Homey | Homey!
