I’ve 2 separate gardens, the first one has 2 zones and ( names: zone 1 and 2, they irrigate the left side and the right side of this garden) the second only one (Zone 3). I would like to connect zones one and two, to avoid, as it often happens, that zones one and two are watered on different days.  example: has watered zones 1 and 3 today, tomorrow it plans to water only zone 2. can someone help me?
