Thanks for sharing. I find it particularly interesting that you found SSRs that can directly switch the sprinkler solenoids. Many existing solutions use an optocoupler (triac output) plus a triac for each station, mainly because the optocoupler itself cannot switch high current. The SSRs you found have sufficient output current, and yet are pretty small.
