The Apex does not have any math capabilities, so there's no programmatic way to count how many times it has run. If you are concerned about a siphon, be sure to install the ATK's anti-siphon fitting above the PMUP in your ATO reservoir. When installed correctly, it's impossible for a siphon event to occur.
Thank you. Yes, for the ATK reservoir, I put a check valve in place above the PMUP to prevent back flow. My main concern is related to an automatic water change where the line removing "dirty" water in the sump will be below water level and was concerned that my ATK would just keep topping off to cover up a slow leak related to the AWC potentially and was hoping there was a nice way to check for this somehow with a code and error alert. I've seen others put a solenoid valve to break a potential auto siphon on systems like this (e.g., AmroAzul has a YouTube video describing this here: ). Thanks again for putting together this very helpful series.
Yes, this is commonly done by using a virtual output to monitor the optical sensor, then add a Defer timer and any other exceptions you'd like, such as ignoring the sensor during Feed mode. Then in your EmailAlm program, replace the line that monitors the sensor with a line that monitors the virtual output instead:

If you flipped the float valve around, be sure the water doesn't trickle down onto the optical sensors because that can cause faulty readings. The optical sensors should face the opposite from the valve exit.
For sure. I flipped everything around so the water exits on the back side of the optical sensors. Another point of user error is I was only getting ~20sec pump runtime and a dribble of water and then it dawned on me that the float valve was closing way too soon so a minor adjustment of that was in order. I also enabled logging on the ATK_PUMP to give me an idea of how often and how long it runs. That little PMUP is pretty loud!
