Thanks, Perry. I use the KeypadLinc Button Device Controller (KBDC) devices a lot and they make Keypads easier to use and manage for me in Indigo.
Suggestion: Make the "State" field show the state of the controlled device list for KBDC devices.
Suggestion: Make KBDC devices look and act like devices in the Indigo interface and api. If you turn them on/off, then both the device and the corresponding keypad button are so controlled., so it provides a convenient proxy to use for control. Triggers can be attached to do things when KDBC's change state.. Again, this provides a convenient proxy for attaching actions.
Suggestion: Make the "Last Updated" field in device list for KBDC devices contain accurate info (currently all my KBCD devices were last updated 2001-01-01 00:00:00).
