I’m finally getting around to implementing AutoWaterChange (AWC).
Ive just run the drain line to the sink using RO tubing and am using a jebao dp4s dosing pump via Michael Lanes adapter board.
I’m using an optical sensor for HighWaterMark (doubles as my ATO sensor too) and a non-contact for LowWaterMark in the pump/return chamber.
note: the “Optical sensors” extension box is setup for optical only, so I had to change the pins on the non-contact sensor and resolder the jumpers. So consider this an advanced thing & ask Rob if in doubt.
I’ve already got a float valve, drilled at a high level that I use for my ATO fill (RO gravity fed via an RO solenoid mounted to the side), so was planning to tee my AWC_fill line there also, to ensure there was redundancy against over filling).
My ATO RO fill solenoid is hooked up to DC3, which has a hardware failsafe with the float switch attached via the optical breakout also. I really like this feature. I may get a 2nd RO valve so I can use that feature for my AWC fill line also.

So now I’m trying to figure out the logic in reef-pi.
What I want to achieve is something like:
At scheduled time, turn off ATO, turn on DrainDoserPump till it LowWaterMark sensor is activated (or X minutes pass, as a safety), then turn on FillDoserPump till HighWaterMark is reached.
I think I can achieve this using two ATOs, tied to the High and Low water marks and logic in a macro; but I can’t see a way to connect the ATO system to the pumps setup as dosing pumps.
Running reef-pi 3.4 currently, so maybe I need to upgrade?
maybe this is something @robsworld78 or @Ranjib has seen before?
