I wanted to be able to integrate my Ring cameras and doorbells into Hubitat - this was the one thing that SmartThings had that Hubitat was lacking for me. I wanted to be able to control the lights/siren on cameras and also get battery reports as well as motion/button pushes. So I wrote an integration that half uses their undocumented API but still relies on an Alexa routine to trigger motion and button presses.
I wrote some pretty basic documentation, you can find the documentation and the necessary app and drivers at GitHub - dcmeglio/hubitat
I have tested with the devices I have - Doorbell Pro, Spotlight Solar, and Floodlights. It's working for me! Feel free to give it a try and let me know how it goes. I likely won't have a chance to work on any bug fixes till the weekend. Just as a note, while I've been a developer for many years, this is pretty much my first groovy dev effort and also I've only been working with HE for about 3 weeks now so I'm still a bit of a beginner.
