I bought one of these - https://www.jbhifi.com.au/products/connect-smart-remote-gara…
The instructions have it for a garage door that rolls overhead rather than a traditional door that rolls up for the sensor location.

Has anyone configured this to be for a traditional door?
Just to clarify, by "traditional" you mean you have a Roller door, not a Sectional/Panel or Tilt? See here for door types.
From the instructions it looks like it only works with the Sectional/Panel or Tilt. However, the sensor is only looking to confirm it's orientation so it can tell you whether the door is open or closed.
If you have a Roller door and you can place the sensor where it comes to rest horizontal with the door open, it should work. Sadly I reckon this will be on the outside of the door rather than the inside otherwise it will likely get squashed as the door rolls up.
