Where can i find the github SmartThingsCommunity/SmartThingsEdgeDrivers in a driver Chanel?

Production channel Edge drivers are those that get downloaded to your hub when the fingerprint (Mfg Code/Model) of your device matches the fingerprints defined in the driver configuration. Beta channel drivers include the Production drivers, changes to the Production drivers that have not been released yet, and new drivers that have not been released. You can subscribe to the Beta channel and download drivers even before you have a device that needs them.

For your device, if it’s registered as a “Thing”, it means that there is no fingerprint match between your device and a driver already on your hub or a Production driver. @Mariano_Colmenarejo is a community developer who does a lot of work on drivers for Zigbee devices, but I don’t see your device fingerprint in any of his drivers. I would submit a request to add your device to one of his drivers here.
