My irrigation system

Just wanted to share my irrigation setup. Currently using NodeRed for automation, but I think I will also try out the awesome irrigation component by @klogg (see here)

Hardware is a Sonoff 4CH Pro R2 running ESPHome and a doorbell transformer. Currently only using one zone, because the others need repair…


Hi I’m in the process of building a similar project with a sonoff ch4 pro r3. Do you power the sonoff with 230v and the relays with 24volt?

This is super cool. Thanks for sharing! (just realized how old this is but… still thanks! lol)

Correct. The transformer drops the line voltage to 24VAC to power the solenoids.
