A Simple Smart Plug, privacy focused, fully open source and unreliant on anything. Simply plug in and use.
SSPlug is made from easily accessible and relatively cheap parts so even people who are more down on their luck than others can make and use it. Building one requires knowledge on reading electical schematics, basic use of tools such as a soldering iron. A computer is also required for flashing.
Below is the schematic as well as the parts needed to build one.
Required parts (from left to right of the schematic):
- 1x Male electrical plug
- 1x Kipp (or other) switch
- 1x The guts of a phone charger (or a similar 220/120V AC to 5V DC converter)
- 2x Diode
- 1x ESP32-C3-Zero (or similar microcontroller which can access WiFi)
- 1x 2N3904 NPN Transistor
- 1x Relay (must be 5V but the amperage depends on the user device)
- 1x Female plug
- And some wire, and optional but highly recommended is some form of box to put all the electronics in (e.g. a waterproof kitchen container, a large junction box etc.)
Download the code from SSPlugSource/code, and download and install ArduinoIDE then open the code.
Flash your microcontroller by plugging it into your computer and selecting it from the list, then just upload using CTRL + U or pressing the upload button.
You have now flashed your smart plug.
