I have an aeotec z-stick gen5 which I’ve installed on a raspberry pi. Openhab2 finds it, but I’m having trouble pairing it with my first device, a first alert combination CO/smoke detector. The stick is changing colors from red, to blue, to yellow, which I understand is normal. According to the manual to the detector, putting the batteries in and holding down the button while sliding in the battery slot should put it into pair mode. I do this after pushing the pair button on the stick, but I cannot get this to work to save my life. I’ve tried all different variations, and I can’t seem to get the stick to pair. I do not get any feedback from the stick that it is in pair mode, either a chirp or a change of color on the LED.
