Hop, skip and jump: Mesh network/topology mapping questions

Yes. See the tutorial here You’ll need to purchase a Digi USB dongle which cost $49.

I purchased the dongle and followed the tutorial and it works perfectly. I found that the lock on my front door was connecting via a SmartThings outlet located in another part of the house instead of the Zigbee light switch I’d installed for the front porch light which is 3 feet away from the lock. In order to get the lock to use the light switch, I unpluged the SmartThings outlet the lock was connected to and voila, lock now uses the light switch for much improved signal strength.
