You are far smarter then those of us who have to carry the smart phones for work!

That looks wonderful. I have the '92 version that still works as long as all the contacts are clean. When it is very humid they seem to jump around. The black tank is always susceptible to trash causing it to read full even when empty. I would like to see more about the pressure system for the fresh tank. It is always confusing when the indicators are at set points ie. If you are gallon less than full you are at 3/4 of a tank until it jumps to 1/2. Then I have to remember hpw many gal is full to calculate wha is left. In a perfict world it would count down from total gallons 40,39,38,37....
Likewise the battery is good fair weak. It can b weak and you can turn off a light and it goes back to good. It would be wonderful to know numbers for that. Not to mention would love the temp. I would put one sensor outside and one in my freezer. I don't need to know if I am warm or cold, but my beer in the frige is another story. I look forward to hearing more.

BARTS, what happened to your post that recommended the Raspberry Pi and Bluetooth? It used to be up there before post #55. I did go check out the Pi and it's a very powerful processor card. I'll probably adopt it for other uses where there is an existing WAN, like at the new house.

Anyway, the reason I'm back on this old thread is that I stumbled on a pile of PCBs for this old design. I recall there is one error on the boards where you have to cut the power traces for the pump and maybe one other place in order to get it work right. Anyone want them, they are up for grabs (4 total). Three of them have the resistor network on the edge for converting the old 4-wire monitor system to the newer (only 35 years old) system.

This is some damn cool stuff, sub'ing this thread for some summertime reading! Short term I won't be doing this kind of thing, but if I end up holding onto my AS this is exactly the kind of modern upgrade I would want to do!

I was hoping there would be an easy way to install the new sensors. Guess not.

The easiest sensors to install are the visual ones. When the shower pan won't drain, or the toilet won't rinse, time to dump the tanks. Who needs all this electronic gear? It just leads to the wife pushing buttons and declaring I have to go out in the rain to dump the tanks instead of getting ready for bed. Pooba! The calibration is probably bad anyway and there was plenty of volume left in the tanks for the night. Pooba!

PS I do admire Zep for his high level of electronic skills demonstrated in this thread.

The cat litter box lives in the shower. Makes a bit of a mess when the gray water tank over flows. It would be nice to catch it before that happens.
