SmartThings Multipurpose Sensor won't connect

Hey everyone -

I’ve had a SmartThings Multipurpose Sensor connected to my system for quite some time. Battery went dead, so I replaced it and couldn’t get ST to recognize it, so I went through the exclusion/removal process and figured I would re-connect from scratch. I can’t. It does not see it during discovery. I insert the battery while pressing and holding the small white button until the blue LED flashes, but nothing. This should be so simple.

Any suggestions for me?


Try excluding it again to make sure it’s fully off.
Verify in the IDE that you can’t see it.
Make sure you are holding it close to the hub when pairing it.
