Is BLUE Lite a drop-in replacement for my StorMax monitor?

The BLUE Lite device is intended to have the same functional capabilities as the StorMax monitor

That is the intention. The BLUE Lite device is intended to have the same functional capabilities as the StorMax monitor in its ability to read both temperature and moisture cables. It can read both 2-wire and 3-wire cable configurations. Note: 90% of the systems in the field currently would fall under a 2-wire setup.
