For anyone reading colin_ha’s reply and thinking ‘nah - can’t be’, you are wrong. If you are chasing an issue and factory resetting your lock, restarting your hub and trying secure vs non-secure, move your hub closer to your front door.
I realized after reading it (and going through factory resets, changing zwave sticks, the whole 9 yards) that I had issues yesterday pairing my battery powered motion sensors across the house, but when I was in the garage with my hub they paired immediately.
Bringing my hub closer to the front door via extension cord and leaving it there for 15 minutes after pairing it got most of the information in the device. I didn’t have lock/unlock surprisingly, so I re-interviewed and bob’s your uncle it’s all there.
Don’t forget to move your hub back and reheal your network.
Want to call out @NathanCu’s amazing reply here. Hoping this helps get his reply to the top of Google.
Pasting his steps here to help as well. Again, YOU NEED TO HAVE YOUR HUB RIGHT NEXT TO THE LOCK. Taping it ontop of the lock worked for me. I also tried S2 Security while checking “Force Security” and selecting S0 Security before the lock finally paired. I’m not sure which one eventually did it and I’m not excluding it to find out. @djbrooks022 has a great write-up on this as well, tagging him so he can get some great credit (and potentially update this for Z-Wave JS UI since he’s top Google result for “schalge connect home assistant”).
