Does anyone know how to stop the LED in this motion sensor from flashing whenever it detects motion?
I'm not sure there is a way to do this within Hubitat. I have seen other posts on this forum where folks take apart the sensor and 'cover' the led with liquid electrical tape or some other form of coverage. I'll tag those posts if I find them! The flashing can be a bit annoying especially when the room is dark.
A man can fix anything if he's got enough duct tape.
As a person who has been trained in the formal art of engineering, we were also taught that a critical fix procedure is "to bang it".
In my experience, the equivalent for Hubitat is "to reboot it".
