The above board was intended neither for the Raspberries nor for Mini PCs, but the code is Open Source and shouldn't be too hard to adapt.
- kkielhofner 3y agoIn the Home Assistant community most GPIO and other duties have migrated to ESP devices and the excellent esphome[0]. I have at least 10 devices around my home and it's fantastic, I haven't wired up GPIO to a Pi or anything other than a $5 ESP8266/ESP32 for years. Another instance of using the right tool for the job. [0] - https://esphome.io/index.html https://esphome.io/index.html
- squarefoot 3y agoYes, that would likely be an even better and cheaper solution if one doesn't need to drive GPIOs from a complex OS such as Linux which would require a fatter board than an ESP one.
- kkielhofner 3y agoIf you haven't tried it you may be surprised by what HA + esphome offers with the 8266/32. That said, the link you provided is potentially a great add-on for someone who wants/needs the logic available on a real Linux host!
