Hello,

I have at home some lights of 2 brands - Philips and IKEA. I want just one device in Homey app which would be able to turn On/Off lights, Dim it Up/Down or set the temperature of all active lights together at the same time.

So I created an Virtual Device (see on the pictures). On/off function is working good, but dimming and setting temperature doesn’t.

It’s pretty weird. This is the problem:

When I set a dim level on my Virtual Device, it look’s like IKEA lights have different range of dimming. But when I go into the specific device of the IKEA light I see that the dim value is set right - but it doesn’t represent reality.

And also temperature doesn’t work very well. There is also flow for one of my IKEA lights: [https://homey.app/f/QxPuxu](https://homey.app/f/QxPuxu?fbclid=IwAR2MNDBwgaj_z4x9G2-n_ks-M7PBlRXU1TLbpH6cuUAMdyvkWjHgDmEx3dk)
