Hi,
I have a problem that I hope someone else knows the answer to.
I am trying to get a flow working that starts with: “When… Turned On” but Homey does not seems to trigger when the lamp is ON. The thing is that I would like to create an auto dimmer flow for a couple of Philips Hue lamps that are triggered with normal light switches, and as you know if I turn on a Philips Hue lamp with a normal switch it will light up 100%. Here I would like Homey to detect that the lamp is turned on and automatically dim it to a lower percentage.
It worked once 🙂 but now it will not detect if its on or not. I was thinking if there exists a “When…” scheduler that I can trigger every 30 second to dim the light but this will be a ugly workaround but great to have if I can’t get the “Turned on…” to work.

Don’t think Homey sees the powering on of the bulb as a “Turned on”. Not gonna work.
When switched on by Homey the flow will trigger tho.

Hue are not made to power of, they should be switch by triggers on/off.
BUT if you want to persist powering them off here’s what could help you:
1 update to the latest hue firmware on the bulbs
2 now you will be able to set the power up behaviour of the light
- default it is warm white full brightness
- if you select “last used color and brightness” it will turn back to the last state when powered on
Enjoy! 🙂
