Hello, I have a motion sensor that measures light intensity in lux, and I use it to notify me if the light has stayed on above a certain threshold. However, sometimes the sensor gets stuck at 20 lux even when it’s dark. I would like to create a virtual button that, once pressed, resets the value to 0 lux. Is it possible to modify this value, and if so, could you guide me on how to do it? Thank you. ---

You can’t change sensor values for normal devices. Perhaps you can use one of the virtual device apps to create a virtual motion sensor that can be reset like that (since those apps allow you to set capability values from flows). ---

Okay, thank you, I’ll try.
