When querying for my water pulse sensor via the local API (http://flukso-hash.local:8080/sensor/water_sensor_id?version=1.0&interva...) with only the tap in the kitchen running I get values like:
[[1361228944,306],[1361228945,306],[1361228946,306],...
The pulse meter only pulses once per liter. What does the number 306 mean? Am I wasting 306 liters per minute if I keep the tap open like this? Or... if I keep the tap running like this I will have used 306 liters in 24 hours?
In other words, the liter per day unit vs. the interval confuses me. If the 306 is the liters used per minute, why does the unit read lperday? With interval set to minute and unit to lperday I get a reading per second over the last minute of what exactly?
Thanks a lot!
The water and gas dimensions for the real-time API are indeed in liter per day. Expressing this in liter per minute would result in low values (0.21 in your example).
Don't be blinded by the 'day' in the denominator. We also express car speed in km/h although we do not tend to drive at a constant speed for an entire hour. km/h is just a useful dimension resulting in quantities between 0 and 300.
Thanks Bart, the km/h example clarrifies things for me. I think I get it now. :)
