Ok, so I have been using “group” app to set percentage levels for my RF fans, lights and blinds.  
I notice that every dim or set percentage commands that I give to Alexa, it executes the correct percentage in the Homey device but somehow no feedback is given to alexa from Homey that it is correct.

I have not set up to test it direct with a dimmable bulb so I’m wondering if anyone else is experiencing this?  
This doesnt happen for my Yeelight via the xiaomi app if I recall.
