Hello @farlicimo.
You can remove the contact from being monitored by Home Monitor. The SmartThings app menus are not very intuitive, so many people don’t know they can do it!
- Tap on ‘Home Monitor >’ from your Favorites screen
- Tap the gear icon in the upper right corner
- Tap where it says ‘Security’ - not the on/off toggle, but the rather the text
- Tap ‘Set up Armed (away) sensors’
- Tap ‘Monitor Access - Use all open/close sensors’ - not the on/off toggle but rather the text
- Now on this screen you can select or unselect which devices you want to include/exclude
- Tap ‘Done’
- Tap ‘Done’
- Now do the same thing for ‘Set up Armed (stay) sensors’
Hope that helps, and you don’t have to change drivers
