Modular NodeMCU Relay Controller

thingiverse

I needed an all-in-one box to control and monitor multiple things at once. I've got this box controlling two LED panels in my garage - Bay1 and Bay2, a PIR sensor at the front of the garage, a Reed Contact Switch that tells me if the garage is open or closed, an LED panel over my workbench, and LED strips shining down on the front of my garage door. And it's all managed from a single NodeMCU running Tasmota Firmware. I started with a relay box from Wickwire and a NodeMCU mount from Boltz, then added my own modular component bays with relay enclosures. There's even a spot for a dRok voltage regulator that I ended up not using - plus a block on the back where I melted two wire screw-down posts into place. All high-voltage components are safely walled off and separated from their low-voltage counterparts.
