Every time you start printing on your bambulab printer the light turns on personally I find it annoying for this audience this Blueprint has the purpose of turning off the LED of your bambulab printer when it switches from the state in preparation to runnig.
To be able to use this automation it is essential that you have imported your bambulab printer into your home assistant. For this you need an integration that can be installed via HACS
It could happen that if you start a print from the micro SD and not from the Bambu Handy printing history, if the printer status sensor does not switch from preparing to running the light will not go off.
