I’m fairly new to the platform, but one of the things I’m most impressed with is RBoy’s Smartapp: [RELEASE] Door lock code/lock user management (create, delete and schedule codes) with automatic lock/unlock, custom user actions and SHM integration
It’s not free, but it’s some of the best money you’ll spend. I have scheduled codes for the housekeeper, one use codes for service techs, expiring codes for visitors, and manage both my Schlage deadbolts simultaneously. It’s awesome.
