The software can easily be configured to run with more or less fertilizers and outlets, as much as the ESP32 GPIOs can provide.

Or you can also compile the software to run both UI and control on one Arduino, as long as it has enough GPIOs for your needs (or an ESP, but I haven't tested that).

-You can of course also just leave out the UI and use solely the webinterface on the ESP. See the [README.md of the project](https://git.xythobuz.de/thomas/giess-o-mat/src/branch/master/README.md) for more details.
