Hi, I have a SmartThing multipurpose sensor (U999SJVLAEA). The battery died recently so I replaced it but it now just flashes red/green constantly like it's in pairing mode. I have tried to reset it but nothing changes. I've removed it from HE and tried to re-add but it doesn't work. Has anyone had any issue with this unit?
I’ve never had a problem with mine, but here are the reset instructions from Aeotec since they have been deleted from Samsung’s webpage:
- Press and Hold the recessed connect button for five (5) seconds.
- Release the button when the LED starts blinking red.
- The LED will blink red and green while attempting to connect.
I would reset it and remove the battery, put HE in pairing mode, then reinsert the battery. If that doesn’t work, move the sensor closer to the hub or a repeater if possible and try again.

Thanks. Tried that but it does not connect, the unit flashes red/green as soon as the battery is inserted. It's only 2m from HE, no walls in between so I would think that would be fine.
Sometimes it seems to me that other Zigbee devices create so much traffic (or there’s a bad device) and it becomes difficult to pair a device. You could try cutting power to other Zigbee devices and try pairing again as a troubleshooting step.
I had this issue a couple years ago when I was trying to add Lightify 4-button dimmers. Peanut plugs were the culprit in my case. I was able to pair all 10 of the dimmers to a second HE hub without issue.
But, perhaps the device has gone bad, or you got a bad battery (which I have had happen).
