It's a simple idea. Plug this unit between a 12v power adapter and your 12v device and turn it on or off via WiFi.
This enclosure is designed for a standard 40mm x 60mm PCB with 30mm of height clearance.
I have the ESP8266-01s flashed with Tasmota so it's easy to manage.
I'm modeling a set of enclosures for the 6 most common PCB sizes so I can easily print a box for whatever project I'm working on.
The buck converter drops the 12v input to 5v in order to power the relay module.

The ESP modules are so cool and cheap

For sure. I've got a few of these. Mostly I use them for controlling LED strip lights.

Yeah it took me a bit to figure out how to program them, I use the serial usb with a short button

I run everything through MQTT commands and the logic is handled by NodeRed. It's a lightweight system I have running on a Raspberry Pi.

Oh dang I haven't tried MQTT yet, anyway cool, it's a nice build, no wires all over the place on a breadboard ha
