Hi,

You can fix variable with sending data. In the firmware, you must add this function for place value in this V_VARx

So, place this function into your setup firmware.

Where in this case

MyMessage var1valve(CHILD_ID_SPRINKLER, V_VAR1);
MyMessage var2valve(CHILD_ID_SPRINKLER, V_VAR2);

This loop repeat for each relay (i) and you can set any value at the end (1) for one minutes and (5) for five minutes.

That's all.

void goInitiateValveTime() {
  for (byte i = 0; i <= NUMBER_OF_VALVES; i++)
  {
    send(var1valve.setSensor(i).set(1));
    wait(50);
    send(var2valve.setSensor(i).set(5));
  }
  wait(50);
  lastValve = -1;
}

Refresh Home Assistant just after run one time your script and value appear in your persistence file.

Regars,
