How to exclude/delete schlage BE 469ZP that no longer works

You can force delete a device in either the new Advanced Web App or in the community developed ST API Browser+. Since you have a Schlage lock, I recommend installing the [ST EDGE] Z-Wave Lock PH - Devices & Integrations / Community Created Device Types - SmartThings Community from @philh30. The production driver and the beta driver are currently in sync, so you can install the production version. It offers more configuration and settings options plus you can use unlock code names in Routines.
