Using my Imou camera with the ONVIF integration i don’t have any switch to enable or disable with automations the human and motion detecttion, but only binary sensors that tell me if the human and motion detection is enabled or not.
What to do to have the ability through automations to enable/disable them?
Contact the manufacturer and get them to update their ONVIF implementation.
Home Assistant can only discover ONVIF controls that they (the manufacturer) have chosen to expose.
