RFX meter water in domoticz

[danjard_mathieu]

Hello all
First, here is my config :
Raspberry pi B+
Domoticz V2.2563 (Last stable)
RFXCOM
Mysensor serial gateway V1.5 (Arduino uno + NRF24L01)
Watermeter code onto an mini pro + waterflow sensor.

I recently add a water meter on my system and i've got a strange behaviour.
When i had it to domoticz, it appear as a RFXmeter and i've got the posibility to select it as energy, gas , water or counter.
When i select counter, it show the recorded pulse number which look quite right but when it is selected as a water meter, it display strange value, i.e , for 1 pulse recorded , it display 0.010m3 water ...
I can't figured where the convertion is done because on my sketch, the PULSEFACTOR is right and the serial is giving the right water volume.
I didn't get any chance to look onto the gateway debug yet.
If somebody have an idea, you are welcome.

Maybe better to ask on the Domoticz forum if the water meter is a supported device.
