In this video, I show how I automated my shop air compressor so it shuts off whenever the lights go off — making it nearly impossible to forget and leave it running. This simple shop automation uses a smart relay, momentary switch, motorized valve, and auto drain to control air flow while keeping the compressor powered safely overhead.
I walk through the wiring, components, and setup process using a Shelly smart relay to integrate the compressor system with my shop lighting. Now I can control the air system from a wall switch, my phone, or automatically when the lights turn off — preventing wasted energy, unnecessary compressor wear, and overnight run time.
If you run a fabrication shop, garage, or home workshop, this is an easy automation upgrade that improves efficiency, protects your equipment, and adds smart control to your workspace.
Perfect for welders, fabricators, mechanics, and DIYers looking to modernize their shop with practical smart controls.
