I have several SmartThings hubs which are in various properties (not in the same home), all managed by one HomeAssistant instance. When I add them to HomeAssistant, same named devices show up with a number appended to them. For example, hub one and two have a device called ‘Front Door’, which shows up in HA as ‘binary_sensor.front_door_contact’ and ‘binary_sensor.front_door_contact_2’. This can be confusing to manage, and it would be much nicer if I could set up an entity prefix when setting up the SmartThings integration like ‘house_1’ and ‘house_2’, so the entities for a hub would be something like ‘binary_sensor.house_1_front_door’ and ‘binary_sensor.house_2_front_door’.
Thinking about this, it would be a nice feature for other hubs like the Philips Hub or Vera hubs, the ability to specify the entity prefix.
