Uploading the code to Github is a choice from developers to share their drivers publicly and it’s not related to the way drivers can be currently shared. If you ask them privately, they might share it with you the same way, the ones that have created drivers so far are very active Community members and the team commented in the post I shared that they plan to communicate with them regarding open source drivers, but this can take a while.
On the other hand, there are plenty of samples from the official SmartThings drivers:
- SmartThingsEdgeDrivers repo
- Tutorials (Zigbee, Z-Wave, LAN)
The developer documentation about the development and the Edge reference where you can find more specific details can also help you out.
If you’d like to see other examples, you can share your ideas and we will pass them to the internal team.
