Hi, I post my Reef Pi 6.0 build here for feedback and ideas...
The host turns on an Orange pi one, I don't use OPI gpios but only ESP32, with some BNC and gx12 connectors for sensors and jacks (wavemaker pump, dosing pump), I will put another ESP32 dedicated to the led light, and use Reef Pi as failsafe for my heater thanks to a tasmota plug. All is in evaluation and testing....
