i edit the app DoorCam to get it working for Home Assistant instead of Domoticz.
create an input_number helper in HA like: input_number.showdoorcamtoon
fill in the configuration menu with your camera, HA server adres and entity_id.
the token is a very long string, so you can edit the file: /mnt/data/tsc/doorcamha_userSettings.json manually to copy/past the token.
i use NodeRed to set the value of the input_number.showdoorcamtoon see screenshot.
