Monoprice zwave plus door contacts

i am in the middle of switching from Smartthings to Homey and have a bunch of monoprice zwave door contact sensors that i can’t get into Homey…any help?

If there is no app for these devices, then these devices are usually not supported by Homey.
However, you can try to pair the sensors as generic Z-Wave devices: Devices → + → New device → Z-Wave
If this does not work, you will not be able to add the sensors via detours.
