New incantation acquired. Thank you for the help!
So now I am thinking a 110v normally close brass 1/2" valve, switch on by a combination of an ESP32-C6 and Non-Latching Mini Relay(adafruit:product:4409 (I couldn’t make this a link I guess lol)) over Zigbee (or blue tooth to start). With probably a really simple API consisting on zone (currently one) and time to be on.
The rest of the code I would rather be in home assistant or something.
