I want to set a distance to turn on and off the display using an ultrasonic sensor. MMM-PIR-Sensor has that functionality, but it only works for a PIR motion sensor. MMM-Swipe uses 2 ultrasonic sensors, but it doesn’t have the power-saving mode that I need. MMM-NearCompliments also uses an ultrasonic sensor, but I don’t understand if MMM-PIR-Sensor needs to be installed to have the power-saving mode feature.

Any help is appreciated, thank you!
