Currently it’s around 40’ away, but I’m also using a z-wave repeater.
The repeater does not help during pairing of the lock. The lock needs to be in close proximity of the panel to pair properly. 40 feet is too far. Bring the lock within about 6 feet to pair.
After pairing, wait a minute for all the data transfer during pairing and then move the devices back to their permanent spot and run a network rediscovery on the panel. The network rediscovery helps map the mesh routes and lets the repeaters help the lock signaling.
