Welcome, @SouthbayTechy! You’ll be happy to see we offer a Tilt Sensor in the Works With Ring section of our website. As for a garage door opener, there is always the option to attempt integration through Alexa enabled devices, or, as you stated, smartthings, but it is not on our Works With Ring compatibility list at this time.
We are always working to bring our neighbors new devices and features, and will certainly share this feedback with our teams! Feel free to make any additional feature requests in our Alarm Feature Request thread.
