Device Type Handlers: dead?

[derekwbeck]

Are custom device type Handlers DTHs dead?

I was using one for the Enerwave Ceiling Mounted Zwave Motion Sensor. After successfully adding them back to ST hub v2, I’m having trouble with the DTH. It shows the icon as if it has motion nonstop for one thing. Just trying to narrow down my troubleshooting.

Thanks!

The End of Groovy Has Arrived

Beginning September 30, 2022, at 00:00 (PST) we will start migrations of Groovy device DTHs as well as SmartLighting and SevereWeather SmartApps, two of our most popular Smartapps built on Groovy. On October 15th 2022 certain functions of the legacy developer IDE, such as the creation of new DTH’s, Smartapps, and debugging tools will be removed from the SmartThings platform and will no longer be supported. After migrations are complete, this means that devices and automations previously using Groovy will now exclusively operate with our latest hub and cloud technology. Recognizing trends within the smart home industry, SmartThings has been working diligently to evolve our platform into a modern REST API framework. Lua-based Edge drivers are a major step, which is being followed quickly w…

FAQ: I have no idea what Edge is. Is that a new developer tool? (2022)

As of September 2023, SmartThings has now almost completed transition to a new architecture, part of which is called Edge. The Samsung-hosted free groovy cloud gradually went away beginning on September 30, 2022. For hub-connected devices, including Zwave and Zigbee, the DTH replacement will be Edge Drivers, which are written in the Lua programming language and will run locally on your own hub. IF YOU ARE NEW TO SMARTTHINGS If you are new to SmartThings, the basics of the SmartThings architecture are pretty simple: A) An “Edge Driver” is code that runs on your SmartThings/Aeotec hub so the hub can talk directly to an individual device. If you don’t have a hub, you can skip all the rest of this thread: it won’t apply to your setup. B) If your device uses a “cloud to clo…

Thank you. Can you clarify: so existing DTHs may continue to work for a bit, but new ones will require the new coding. Is that right?

@derekwbeck

so existing DTHs may continue to work for a bit,

ST is currently in the process of migrating devices from groovy device handlers to Edge drivers. The current time frame is Q1 2023 for it to be completed.
