Great answer Hedda!!
So it seems there is not a high activity around that request.
When searching for my devices in blakadder’s unofficial Zigbee Device Compatibility Repository](https://zigbee.blakadder.com/) I see that my devices show up with the icons 1) Tasmota 2) Zigbee2MQTT & 3) ioBroker.zigbee.
So since, if i interpret it correctly, there is not any solution at the moment for me to get the functionality to controll 3 colour areas with my Hue Gradient Signe floor lamps I am wondering what my options could be. Is it to sit tight and wait until the commuinty find a solution that i could use? Or, could I pay a few extra bucks to get the Hue Bridge, connect it to my Zigbee controller and use that to get the functionalities. My main concern is that I would like to avoid having several phone apps to controll my lights. I would like to have all the controll in one app (Home Assistant android app).
In the link Migrating from a Philips Hue Bridge to the ZHA (Zigbee Home Automation) integration, if I am not missing anything, it looks like the hue devices have been connected and are being controlled (but only with the basic functionalites). If this is the case, this is the same situation that I am in now, being only able to controll the lights with one colour.
Sadly I am not a Python developer so cannot do it by myself.
