Homekit icons

Hi all
Can anyone tell me if it’s possible to set the device class for a binary sensor and choose which icon is shown in the apple home app?

I have tried to create binary sensor templates for each device class, but only a few works and the rest is just showing as a motion sensor.

I would like to use the lock/unlock icon for showing whem my house alarm is set and I would like to use the red flashing light for when the alarm goes off.

Hey.
Have you managed to solve this problem? I have exactly the same challenge with my binary sensors.

Hey! I would like to know if you managed to solve this problem as well.

I came across this post but I’m not sure how to do it, I’m new to HA.
