Smart Home Control Panel
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 data: message: command_screen_on data: 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 data: message: command_webview title: "/lovelace"
You can find more details in the documentation of the Home Assistant Companion App
