It sends one call to the bridge which then sorts however many lights are in the scene programmed in the Hue bridge. The Hue zigbee uses a proprietary version of zigbee, not just any zigbee device use it, and it seems to be far more efficient at communicating with the lights than using Homeys own zigbee system. So as I understand it, if using Hue scenes that you have created within the Hue phone app, not Homey, Homey just sends one command to Hue, not 10 for your bathroom. I suppose in effect the “group as a device” is done in the Hue hub
I understand what you’re asking but I’m fairly sure that that would require Philips Hue to change and not Homey.
