Apart from the fact that sprinkler systems are almost always 24VAC and every commercial sprinkler controller I have ever used or investigated use optocouplers/fets/triacs I don’t really have a good reason to get irritated by homebrew designs that use relays, but I do get irritated. I think the irritation comes from wanting to really learn-by-copying how to design these circuits and many hours searching for exemplars…

Have you looked at OpenSprinkler?

Anyone else have reliability issues with the ESP32? I have a few of them connected to various wifi networks, and after a couple of years they always seem to disconnect and need a power cycle before they'll reconnect. I understand they might lose the wifi connection, or their DHCP lease, or there might be interference, or something blasts too many packets at them, or a TCP connection hangs or gets RST... But after any…

You dont "expect" anything, you test the connection yourself and restart it when needed:

    if uping.ping('8.8.8.8')[1]==0: machine.reset()
