This may be a better explanation of what i am doing.
The 2 led's represent the 2 solenoids that the relays are controlling.
this is mounted about 2ft from the solenoids, and everything is powered through a transformer.
at the end of the day, everything stays as is, and i only swap the uno out.
so that's why i was thinking the 6 slaves, into one master (uno or Mega) and a rotary switch to power the selected slave.
david_2018 mentioned using switches, what would be the proper terminology to search for, to read up on that.
Below is one of the sketches that i run, the only thing that changes from 1 sketch to the next is the values of the 1st 12 const int's which determine the delays, the number of loops, number of cycles, and the duration each relay is activated, .
in the example below, once powered up
2 hour delay,
Mrelay activated for 5min, 10 min delay, Srelay activated for 5min, 10 min delay:
repeat 5 times
5 hour delay
Mrelay activated for 5min, 10 min delay, Srelay activated for 5min, 10 min delay:
repeat 2 times
4 hour delay
Mrelay activated for 5min, 10 min delay, Srelay activated for 5min, 10 min delay:
repeat 2 times
