Custom code was written in the groovy programming language and ran in the smartthings cloud. As of May 2023, you can no longer add new Groovy DTH‘s or smartapps to your smartthings account. So if you came here because of a link in an old forum thread, or on another site, I’m afraid the Groovy information is no longer usable. All of this was replaced by a new architecture. Cloud to cloud integrations use the smartthings API. Hub connected devices, mostly Zigbee and zwave, now use “Edge Drivers,” written in the LUA programming language. Here’s the official announcement on those: The process for using a custom Edge Driver in the new … Let me know if you have any questions. I can’t code(definitely not well enough to advertise that I can 😕) and the IDE is pretty easy to use. The community device handlers, and smartapps are where SmartThings really shines.
