When ordering my entire system I ordered 2 water level expansions, 1 for my return pump area and 1 for my ATO
reservoir so that the 2 pumps won't run dry. I have not received my order yet, but looking at the source code it doesn't look like the system can have 2 water level expansions (#define I2CWaterLevel 0X4f). Can I use 2 water level expansions in dependently? Can I return one if I can't?

No, it's hard coded to just one.
Sure, you can return one.

Well, if you are good enough to find that out from the libs, I'm sure you won't mind having a custom module.
I can make one custom WL module with a different address.
Most likely would be 0x48. You can send it back and I can mod it for you. Or I can send you the chip if you think you can do it yourself.

According to the eagle files the IC is only 8 pins which I could replace myself but I am not sure how the IC 'attaches' to the air hose and would not know how to 'test' any changes. I would feel more comfortable if you modified the module. Do you want to email me to arrange the modification of the module?

Can I suggest that you offer 2 water level expansions? I would think people would purchase a second one. It would be very useful to add new functions to libraries to keep the pumps from running dry and sounding an alarm, and to use the water level instead of a DelayOn for the Skimmer during a water change.

The 8 pin IC is the sensor. That's not what needs to be changed. It's the tiny 5 pin smd IC that needs to be changed.
PM me for RMA and I can mod it for you.
