Hi! 👋 I'm the creator of openHASP, a free and opensource firmware for Home-Automation switchplate devices with a touchscreen.
While the firmware is free for you to use, the hardware to run openHASP unfortunately is not... We currently support over a dozen configurations for development boards and off-the-shelf devices.
There are still plenty more devices on my wishlist. You are free to chip in or buy me a coffee to keep me coding all night !
I regret to inform you that Buy Me a Coffee is discontinuing their partnership with PayPal. Please use the Donate button on the Github repository instead.
