I would qualify my disorder as PA-OCD (Pool Automation OCD), haha. I haven't yet got into other home automation but that may be in the works after this project.
No...but they are FREE and FUN. Bare minimum for me would be simply Pool Temperature to have as I move forward later with chemcial automation. But I am interested to see how burying my Chlorine Tank is going to keep it cooler (less degradation in the Arizona heat).- 5 temperature is really needed!!!? Even clorine and acid tank?
Those (OneWire type) would be interesting, I don't know if they exist. Most important for me regarding the pressure sensors was making sure they were reliable. I don't want to mess with replacing and/or having issues with those. That is why I went with the used industrial sensors. Used industrial ones can be found on EBAY, its just a matter of if are they working or not, haha. I was "lucky", and they were cheap enough that I bought extras.- PSI probes seems to be very useful. Could be great to have a digital one-wire version (like DS18B20) instead of analog.
