Electronic spending during fermentation really isn't necessary. I read the time my valve is open as a type of bubble counter. The pressure regulation and CO2 pressure adding during carbonation is very handy. I just set the bright tank to my desired pressure and it handles the rest coming...
ya I have a mechanical spunding Pressure relief valve just incase. Even sending firmware to my ESP32 the pause and restart can build several PSI before it boots and gets to pressure regulating.
RAPT Digital regulator and spunding sounds awesome. I have been working on this for a few years with some success some failures. Looking forward to seeing a commercial product.
