I recently got myself a smartthings hub with the plan to integrate it into Homeassistant using the MQTT bridge.
This is working well, but I notice the presence detection (whilst seems to be very reliable) is currently showing as a binary sensor - Whilst I have no issue with this, there currently seems to be no way of identifying binary sensors as ‘Home’ or ‘Away’.
My Request is to add a ‘Presence’ device class.
on = Home
off = Away
Doesn’t give you the clean solution your feature request does but a work around to give you the front end report you are looking for in the mean time. Replace the generic names I gave below with your entity_ID and add the new sensor to your front end.
