+1 please!
Me too please. I just added a bunch of door sensors and none of them are showing in the HA integration. They ARE showing in the Android app and the Tstat does show them as well.
Only one of my two my ecobees support HomeKit. If yours does, make sure to assign the door/windows sensors to that Ecobee. Then install the Homekit integration into HA. My door / window sensor populated right away. I have not tried the camera yet… I was googling that and ended up here. But my door/window sensor works great.
