I just bought a set of philips Hue White E27 bulbs and the Philips Hue Dimmer Switch. I connected them directly using the Philips Hue zigbee app (without bridge). So far everything works like a charm.
Now I try to figure out how to use the dimming options from the switch in a flow. I can select “Dim-up hold” But what do I put in the “than” column to make the light go brighter as long as I hold the button?
