How do I assign a different Halo colour to a 2nd / 3rd push button or other device (wireless motion sensor or door/window sensor)?

Your push button, sensor or other device must first be already linked to your doorbell. To change the Halo colour, press the push button or trigger the sensor by walking in front of it or opening the door or window. When the Halo Light on your doorbell flashes, press the Sun button sun on the doorbell one or more times to select a different halo colour. You have 12 seconds to complete the operation.
