Cable pass-through for brick

[ScientificHobbyist]

I recently installed seeds as a semi-permanent install on my roofline and I think I'd like to install a controller in my garage. However, the whole exterior is brick / stone and I don't have access to the space behind / above the soffit. What is the best (most attractive) way to create a passthrough the brick into my garage?

The only way through will be to drill a hole, doesn't need to be large if it's just a single wire. The mortar will be softer and less likely to chip as well.
