If I remember correctly, the notifications from app that installed from side-loaded Play store simply just doesn’t work in Fire tablets, and my quick google research found many have complained about Fire devices not getting notification from Ring.
However, I think you can achieve this without Automateit. Try the steps below:
- Add Ring to your SmartThings/Hubitat hub
- Create Fully Browser “device” in SmartThings/Hubitat using the community developed DTH
- Authorize both Ring and the Fully Browser “devices” to SharpTools.io
- Create a rule in Rule Engine. When Ring button is pressed, ask Fully to load “intent:#Intent;launchFlags=0x10000000;component=com.ring.answer/com.ring.answer.presentation.splash.SplashActivity;end” url, which should make the Fully to load Rapid Ring app.
See the post below for some related examples and links to find the DTH.
