As a heads-up, what we have implemented for the upcoming firmware 2.1.6 is some ‘baby-step’ support for flow sensor. In particular, you can monitor the real-time flow rate, and the flow count will be logged onto the microSD card so that you can check the total water consumption. We haven’t planned to add any automatic shut-off feature yet, because we want to collect feedback and suggestions about the flow sensor support before moving forward to add features that make use of the flow sensor for automation and fault prevention.
