Does controlling OSPi with the other GPIOs work?

A project log for MQTT hack for OpenSprinkler OSPi

At the beginning of 2024 the opensprinkler firmware cannot (yet) subscribe to MQTT topics. Can I make a hack to solve this?

Again a small program ( and corresponding programming of OpenSprinkler shows: it works! (From now on, as I directly connected the GPIOs, I did not use any pull-ups anymore.)
