1st - The trigger works like a thermostat. If the lux value hasn’t been above 15 first, it’ll never trigger 2nd - in case the lux card _does_ trigger the flow, the room has to be occupied in order to turn the lights on. That chance will be very low. 3rd - this flow will work only once, or a few times, a day… But when I guess what you want to achieve, you’d turn it around When… -BU FP2 zone Bathroom is occupied And… -logic card [BU FP2 lux value tag] is less than 15 Then… -turn on Bathroom Upstairs light And then -dim Bathroom Upstairs light to 50% And then -turn color of Bathroom Upstairs light to orange You’d daisy chain the “then” cards, in this particular order (For certain lights, the “turn on” card is not needed when you set a dim value, it turns on just because of that) For the “And” part, there’s often no flow card(s) available. The Logic cards are to be used in that case. > [@How to use tags in a flow](https://community.homey.app/t/how-to-use-tags-in-a-flow/9285): > > How to use tags in a flow on 2.0.x There are a lot of questions about using the tags in the 2.0.x firmware of Homey.

When selecting the device you get the option to choose “The power changed” f.e. When clicked you will see the tag(s) coming with this card. We gonna use that tag later, no need in… [![](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/4/4/441f03af3920e71d7e4c61ca60dcdde612a747a8.jpeg "Homey: how to pick a tag from a certain device") ](https://www.youtube.com/watch?v=X-9zO9khx_E) --- _[View the full topic](https://community.homey.app/t/fp2-sensors-en-advanced-flow/94558)._
