I have a Fibaro sensor that detects light levels and I would like to create a Flow that turns on lights when the luminance drops below a certain level. However, that’s not offered as a card for that device when I try to set up a Flow. I’d be grateful for help in setting this up - thank you.

Does the fibaro app have an WHEN card that says something like ‘ luminance changing’? If so, use that in combination with an AND card.

This question has been asked at least 50-100 times, so you aren’t the only one that missed it.

But you should use the “Logic” cards and a whole world will open up for you.  
Like a “is larger then …” in the AND column, there you can pick any capability value, like the lux level of the sensor you want.
