Reply To: Pi açılırken röle bir an çekiyor, sulama vanası açılıyor. GPIO'lar boot'ta ne durumda?

I added the config.txt line, and the glitch at startup has almost completely gone; when I measured it, only a few hundred milliseconds were left. Once I also fitted the pull-up resistors, that disappeared too. The water doesn’t come on before the valve opens anymore, and the neighbour is relieved too 😄 Thanks Cansu.
