[Groovy DTH] Issue with custom capability (stepper display)

@guxdude

is there some other way then the groovy IDE to define the capability functionality in the future?

Edge drivers will replace Groovy DTHs once the legacy platform sunset arrives. (There are already some processes of migration for those in the Hub beta program, but the public migration will be announced later on)

This firmware update for Wi-Fi Hubs allows you to install them and use them correctly.

Announcement | SmartThings Edge for Devices and Automations

Last year, we told you that we are transitioning to an API-first SmartThings Platform. As a part of this, we started investing deeply in improving stability and security. Today we are announcing the beta release of SmartThings Edge - a new architecture for Hubs that use Device Drivers and Rules to execute Hub Connected devices with lower latency, higher reliability, and… local execution. What is SmartThings Edge? We are taking smart home events that would have happened on the SmartThings Cloud and moving them to your SmartThings Hub. SmartThings Edge uses Lua© based Device Drivers and our Rules API to control and automate devices connected directly with a SmartThings Hub. This includes Zigbee, Z-Wave, and LAN devices as well as Automations triggered by timers and other Hub Connected devic…

Note: About this one, I’m confirming if this also happens for Wi-Fi Hubs now that you received the firmware
Update: Yes, they should take into consideration the enabled drivers for this default joining process. You can check which ones do that in the FAQ page included in the thread

Hub Connected Devices Now Use Edge Drivers

Starting on Tuesday, April 26, new devices onboarded to the SmartThings platform will begin to be backed by Edge (Lua-based) drivers. Note, this transition marks the start of a gradual process that will initially include a small number of devices but will expand to cover more over the coming months. This is an exciting announcement, which will be followed up by many more in the upcoming months as we complete the transition away from Groovy DTHs. In addition to support for existing hub-connected device protocols (e.g., Zigbee, Z-Wave, LAN), SmartThings Edge will also enable Matter devices to be introduced to the ecosystem as soon as the Matter standard is finalized later this year. The immediate benefit of the shift from cloud-dependent to local control means users of Zigbee, Z-Wave, and L…
