Hi Guys,
I am desperately looking for a solution to push a message, notification or a command (play musicfile) to an Android tablet that has only LAN, but no WAN (Internet connection).
My Plan was to somehow trigger this but everything is NOT using local LAN:
Pushbullet: Cloudpolling
Telegram/any other Messaging service: Cloupolling
Macrodroid Webhook: Cloudpolling
I could not find anything to trigger something via MQTT Payloads/commands, REST or any other solutions to push anything.
Research was always very vague.
I will not use the Home Assistant Android App.
Does anyone know how i could easily trigger to play a local soundfile/Alarmsound on my Android device?
