Hardware req's for multiple tanks

[jsoeterbroek]

If you would want to monitor multiple tanks, how to setup hardware and config?
A separate aquapi per tank would be too costly.

Theoretically, if you don't mind wires from one AquaPi, you actually could monitor more than 1. I have 2 tanks right next to each other, just 1 AquaPi. The temperature Dallas probes can be daisy chained, and you can have countless I2C devices with unique addresses daisy chained, for your probes and such. And I have access to every other available pin for the ESP32 microchip for users to expand upon.

Now, this is much more modular, customizable and cost effective than Neptune. But, if you have tanks in separate rooms, there is nothing you can really do.

Alternatively, you could just buy the circuit board and build the rest yourself and buy only the components you need.
