Matter bridge bridge/matter.json
Shows these drivers' contact, motion, leak and temperature sensors, switches, outlets and lights on the helper's Matter bridge too, for Google Home, Alexa or SmartThings. If Apple Home has both the HomeKit bridge and the helper, it shows them twice. Endpoint numbers are kept in matter-ids.json. Restart to apply.
Edit the JSON instead (for the settings the form doesn't show; it keeps them as they are).
Saving checks the file the way the helper will at its next start. A restart puts it to use.
