From the project

An epaper switch project with 2 PCBs, controller+touch, and 220AC to 3DC with Relay (Latch or solid-state)

IMPORTANT: This repository contains components added as github submodules. Please clone it using

git clone --recurse-submodules https://github.com/martinberlin/bistable-smart-switch.git or if you already cloned it without them just run additionally: git submodule update --init --recursive

This is a project that started with the idea to use small, and inexpensive, SPI epapers with touch. The ones that I've found available and met that criteria are produced by Good-Display in Dalian. The idea is very simple:
