Smart Home Control Panel


First get an overview in the video:

To turn on the tablet via the Home Assistant app, the Notify service of Home Assistant is used, this can be tested with the developer tools from Home Assistant (replace mytablet accordingly)

service: notify.mobile_app_mytablet
  message: command_screen_on
    ttl: 0
    priority: high

In NodeRED you use the “Call Service” node and select the service “Notify” and the device “mobile_app_mytablet”.
Under Data the command (see above) is then used modified as JSON


This way, a motion detector or similar can be used to turn on the screen when needed.
You can open the Home Assistant app and corresponding dashboards (and also other apps) via the notification. Adjust the link “/lovelace” according to your needs.

service: notify.mobile_app_mytablet
  message: command_webview
  title: "/lovelace"

in NodeRED


You can find more details in the documentation of the Home Assistant Companion App
