I needed a remote to control some ESPHome devices that don’t have a physical switch, so I built one using an ESP32‑S2 and ten leftover keyboard switches. I chose to include one ON button and one OFF button. The setup is based on ESPHome, where I simply added a binary_sensor for each switch (GPIO1 to GPIO10). I’ve included the Fusion360 file in case you want to modify anything, such as switch size, ESP32 dimensions, or key mounting depending on the switches.
