The Arduino I'm using (ATMega328) only has A to D..not D to A.

That is a possibility but one of my stated goals was to leave the panel as is--I want to be able to restore OEM functionality (This is mostly because I wasn't sure how well this would work and wanted a fall-back in case of failure LOL). In addition I was only really concerned with the black tank. Ripping out the KBB means making it work with everything (battery monitor, fresh water tank, grey, black).

I agree: It is far too easy to go nuts with all of the hardware options available these days: Why not replace the panel with a color LCD touch screen and use a Raspberry Pi to monitor everything instead of an Arduino!

That is a cool case/panel!

Adding bluetooth wouldn't be that difficult and I already have a development environment for mobile (Android is much easier/less costly to develop for than iOS).

Lucky you being retired I'm still part of the working masses.
