openHASP firmware

Control your home-automation devices from a customizable touchscreen UI connected via MQTT.

This project is a re-implementation of the popular HASwitchPlate sketch created by aderusha. The HASPone project uses a Wemos D1 mini and requires a Nextion/TJC HMI display. This rewrite removes the Nextion/TJC hardware requirement by using the Light and Versatile Graphics Library on the MCU to drive a commodity display.

openHASP also adds ESP32 and STM32F4 support to take advantage of the additional hardware capabilities.
