Home Automation

As the webui is just interfacing with the device using HTTP POST requests, all functionalities can also be accessed your home automation.

Switch display on/off from Home Assistant

Edit HA configuration.yaml:

rest_command:
  set_photos_display:
    url: "http://<IP-address>/display"
    method: "POST"
    content_type: "application/x-www-form-urlencoded"
    payload: "action={{ action }}"

and add the following to your automation to turn display on:

action:
  - service: rest_command.set_photos_display
    data:
      action: "on"  # activate

or the following to turn display off:

action:
  - service: rest_command.set_photos_display
    data:
      action: "off"  # deactivate

Switch display on/off from Node-RED

For switching the display on and off, photOS expects an HTTP POST request to http://<photos-ip>/display with the content action=on and action=off. Doing a http request from Node-Red is very simple:

Please note that http-request node does JSON encoding of the payload by default. As photOS requires form data, a special header has to be added.
