As I’ve begun to play around with ESP32-powered displays like the Cheap Yellow Display (CYD) and the WT32-SC01 Plus, I’ve mainly been focusing on utilizing ESPHome to do everything. It’s what I started with, yet it’s not the only option. Another, similar tool that others make use of is openHASP, which is a purpose-built tool specifically for building an interactive touchscreen interface. ESPHome can do it all, but openHASP is fairly narrow in its focus. I decided to give openHASP a try and see how it fares, and to be honest, I’m pretty impressed.
