You all might try this... It has basic lock/unlock functionality, and at least it stays on the network. Once I figure the code lock-code thing out, I'll add it back.
The crux of the story is, the "built in" driver changed a few years ago, and it is currently borked, but hubitat staff won't accept that, it's got to be the <mesh, lock, weather, act of god, etc>. An 4 y/o custom driver still worked for lock and unlock, and persists through reboots, but doesn't currently work with Lock Code Manager, so I am trying to reengineer it.
