I tried to install two Hue motion sensors, 9290030675. One works great the Hub recognizes the other but never updates. I tried configuring the failing one with the Hue motion sensor driver or the Zigbee generic motion. The driver change has no impact. Any suggestions to make the failing sensor work?
The two sensors are at the same distance to the Hub, they're about two feet apart.
Remove the sensor that is having problems. Then reset and re-pair it. Should be about a 10s+ or more press on the reset button and then the sensor should be reset and go into pairing mode. Start Zigbee pairing on the hub and re-pair it. See if that helps.
Take the batteries out and leave it unpowered for 10 minutes. That's an arbitrarily long time but it worked on my Hue outdoor motion sensors when I was having trouble getting them back online. When you put the batteries back do the reset button thing and I'll bet they pair up fine. If not, the only thing I can suggest is to first remove the devices from HE and repeat the above.
