Handling of V_FLOW in Domoticz

Post by joshimosh »

Hi,
I have a MySensors pulse counter connected to my gasmeter. There is one pulse per 10 l of gas. I am adding the pulses in the sketch and send them in five minute intervals with V_VOLUME to Domoticz. In addition to that, From current pulse reading and previous pulse reading I calculate the flow of gas during the last five minutes in l/minute and send it with V_FLOW to Domoticz as well (using same child ID for both). For me, the flow (= consumption) is more interesting than just the counter. What I see in Domoticz Is a value given in percent (%).
The documentation iiat MySensors clearly says that flow is l/minute.
What is the meaning of percent here ? Percent of what ? Percent is a relative figure - you need to know the base which this figure relates to, otherwise is totally useless.

Can one of the developers (anyone else is of course also welcome :-)) please enlighten me ?
Of course I could calculate the energy equivalent of one liter of gas in watt or kW and send it with V_WATT to Dmoticz, but my next "project" is my water meter, which definitely calls for l/minute.

My I ask to shed some light on this ?

Thanks a lot in advance
Josh

Hi Josh,

There was no waterflow sensor in domoticz, so i had put the values (l/min) in a percentage sensor, if it displayed 9.8% it was 9.8 l/min

but in the latest beta version, we now have a waterflow sensor, your current water percentage sensor will be automatically be converted to the new sensor type
Quality outlives Quantity!
