Groovy Smart App or AWS Smart App

The groovy platform is in end-of-life stage, and will be going away in about a year. Whether it’s worth it to you to write something new knowing that it will eventually be gone is a decision only you can make. Here’s the official announcement with the timelines (the topic titled as a clickable link).

It’s also important to note that hardly anybody writes their own groovy smart apps anymore, not because at the end of life issue, but because there is now what is essentially a scripting language for smartthings called Webcore and it does a lot of the heavy lifting for you while still allowing you to do pretty much anything you can think of. :sunglasses:

So I think these days most people would suggest starting with Webcore and seeing if that does what you want.
