The (formally known as "Edge Driver-Mc") is a suite of community-developed software drivers for the SmartThings smart home platform. Created by community developer Mariano Colmenarejo , these drivers use the newer Lua-based SmartThings Edge architecture to provide enhanced functionality for Zigbee and Z-Wave devices that official drivers may not fully support. Developer Profile Name: Mariano Colmenarejo.

As SmartThings transitioned from its old "Groovy" architecture to the modern platform, many legacy device handlers stopped working. Mariano Colmenarejo stepped in to create and modify drivers that fill these gaps.

The specific keyword "Mariano shared beta driver" typically refers to a specific build or modification attributed to a community developer known as Mariano (or variants of the name prominent in Latin American and European modding communities).

As GPU manufacturers push toward proprietary, locked-down ecosystems (e.g., NVIDIA’s signed firmware modules), community drivers like Mariano’s are becoming harder to create. However, the demand remains strong. For every user willing to risk stability for performance, there will be a "Mariano" somewhere sharing a beta driver on a forum.
