Use TVOverlay to show Domoticz notifications on your Android TV
Posted: Thursday 02 October 2025 22:25
I came across the app TVOverlay that can show notifications including pictures on a Google or Android TV or google TV mediaplayer, see page https://github.com/gugutab/TvOverlay and this video https://www.youtube.com/watch?v=mdsY084-pr8
As it has a Rest API and MQTT interface it can also show notifications coming from Domoticz!
I did the option with a dzvents script using the Rest API to send a notification including a screenshot of my Domoticz Camera when I have motion on my driveway. You probably also can do this with MQTT but I did not investigate this as I do not use MQTT....
So the procedure is:
1 Install and setup TvOverlay on your AndroidTv, Chromecast or Andoid TV mediaplayer via PlayStore, see https://github.com/gugutab/TvOverlay?ta ... how-to-use
2. Make note of the IP of the TV as you need it in the dzvents OpenURL.
3. Make note of the camera IDX you want a screenshot off to be shown in the notification on your TV
4. Copy below code snippet in a dzvents script session. This example is triggered on my your motion sensor. Change the camera IDX, TV-IP and Domoticz IP and Port to your needs.
Have fun!
