Anyone tried "Wire Sprout" station doubler with Rachio 3?

Moving over from a SkyDrop system, (going to buy a Rachio 3) and need to add a 5th station to a box that only has wires for 4.

Have read about “Wire Sprout” (station doubler wiring kit) and wonder if it will work and/or physically fit with a Rachio 3?

Thanks!
Mark
