My intention is also for NSW holding tank. How do you get your AWC rigged using DDR? I thought DDR is waaaaaay too small for AWC.
I want an alarm to be sent to me when the NSW container water level is getting low, and will trigger a virtual outlet (eg. Low_NSW)
When VO Low_NSW is ON, it will kill the scheduled WC and skimmate purging.
If there are no way to use that "volume left" value, I think I will have to install another float switch.
