ok. i guess i'll leave it alone unless i think there's a problem.

is that all leakshield would use it for? i.e. a binary flow yes/no? i guess i'm not very keen to block the flow in the loop while the pump is running (even though presumably that is how the pump has been designed), it just seems...wrong.

is it worth calibrating (i.e. enabling) the virtual flow sensor on the D5 Next just to use it with the Leakshield? I read some posts saying that the virtual flow sensor is not very accurate, so is there not much value in adding it to the Leakshield config?
