Nice. I am likely to need something like this for my project. Nice idea.

i'm running v2.3219 on my synology. i think this is a beta release? i think my strange values are due to trying to add the values by json, this results in adding it to the todays volume and not resetting the total count? furthermore the positioning of the tcrt5000 is critical in preventing false pulses and this is what is happening now with my meter i think... the small led light on the sensors blinks sometimes very weak when the wheel of the watermeter isn't even near the led....
