Handling of V_FLOW in Domoticz
Posted: Saturday 31 October 2015 18:05
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
