As far as I know, you always need a bridge for Google Home connection or Google Assistant, as this enables you to access via the web and Google Home always accesses via the web.
Hello DarthShadow, but of course you can buy them separately. I have 3 installed at home and with the app you can programme each remote control separately. You can also control the lights only with the app but such a dimmer switch is already practical.
Philips Hue Dimmer Switch
Best wishes and may the force be with you
If the Hue Bridge and Hue App is used, the dimmer switch from the Hue Wellness lamp can be configured to control only the Wellness:
Settings, Accessories Setup, Hue Dimmer Switch, select desired lamps.
If the switch is used without a bridge and app, the lamp can be re-paired:
Switch on Hue Wellness, hold Dimmer Switch as close as possible to the lamp, press and hold the On(I) and Off(O) buttons of the Switch until the lamp starts flashing.
Yes. This is a regular lamp actually with an E27 bulb socket. You can put there any E27 bulb. I also changed the shipped white ambience bulb to a color one.
Dimming from very bright to dark. Switching off and on as with the other hue. I feel that the darkest level is very dark depending on the scenario (colour share).
