So sorry for the long delay in responding. Please try removing "dimmable": "no", from your config.json file. I just checked how I have my contact sensor setup and it doesn't include the dimmable type for that device. Save and restart the server and client listener.
I do not personally own an Insteon motion sensor, so I've no way to test this. Motion sensors were included in the original Homecontroller code that sits at the base of all this, so it technically should work, but I cannot recall if we ever tested it with this specific integration. I am personally considering just retiring my one Insteon contact sensor. I thought I would go ahead and use it, because it was working perfectly as a sensor for closed physical contacts, but now that I've converted it back to using the internal reed switch, I find I have to restart the server and client listener every week or so. Not worth it to me and I have several more Aqara and Mijia contact sensors that are rock solid using Home Assistant with Home Assistant Device Bridge to bring them back into HE.
