I don't know if these kind of irrigation systems are available outside europe too, but maybe check out the Blumat drip irrigation system (DE) or similar systems.
The cones work as indicators and regulate a passive valve based on soil humidity. Completely analog, no smart shit inside. Just clay that expands/ contracts. And a stupid tube.
Or maybe check out Ollas
Drip irrigation is hard to get right. Either you waste a lot, or the plants dry up.
Those passive methods are more efficient and you can maybe even dissolve some mineral fertilizer in the water
I do a poor man's version of that system. I have my drippers dripping into terra cotta watering spikes.
