Hello hive mind, I’ve been having issues using number variables in advanced flows to set the dim % level of a number of bulbs/lights in a room. Apart from making it easier to adjust them all in unison, it also would allow me to modify the value from the mobile app, as you can’t see/edit advanced flows in the app. The problem I am experiencing is for example create a number variable with a value of 15 to set the dim level to 15% instead of the bulbs default 50%. But when the flow triggers it sets them all to 100%. Has anyone else had similar problems? or am I just going slightly mad ha ha… ---

Instead of using values from 0 to 100, you need to use values from 0 to 1. Example: 0.15 = 15% 0.5 = 50% 1 = 100% ---
