Hi,
i built an app. You can connect to a mysensors ethernet gateway and it will display incoming messages.

It's not available through the app store. Here is the debug build of the app:
(link to debug build removed. Download via playstore)
Notes
- The app requires network access rights
 - Installation of apps from "unknown sources" has to be enabled to install and use this
 - 
- See: Settings/Advanced Settings/Security/Unknown Sources
 
 - When connected, the app will keep the connection as long as the activity is in memory.
