Toro Moisture Sensors or any other sensors connected.
Allow each zone to be controlled/use/enable/disable a moisture sensor.
If two sensors are installed (whatever type they may be) allow the zone to select which one it uses (s1/s2/s1+s2).
Current workflow has a sensor control the entire system.
Doesn’t seem appropriate to have one sensor decide if all 8/16 zones should be irrigated.
