It seems you're overlooking a great soruce of power. hydro-power.
if you have enough power to open a cheap Home Depot valve, once the
water is flowing, almost any size turbo valve will deliver more power
than you can use or store with the power supply needed to run the
stamp and valve.
I'm thinking a bicycle type generator.
but, in practicality, if you have water, you have a pipe. if you
have a pipe, you should have room to run wires from the pump.
Also, since underground sprinklers are typically centrally located,
you could put them near the house. and then you need a Stamp at the
house receiving the RF from the remotes.
Thinking this through a little it seems that if you remotly measure
moisture, and send the moisture level back to the house, then you can
adjust watering levels and run times from a central location.
