Description

What happened?

I have a Valve:

Model FK-BV05
Vendor FrankEver
Description Zigbee smart water valve with flow meter and temperature sensor

and gives the value of the variable "Water consumed last. (Single water consumption (Last irrigation)" in dL and not in L. The valu showed is ten times bigger.

What did you expect to happen?

The value "Water consumed last (Single water consumption (Last irrigation))" comes in L

Research direction

Start by locating the device definition or converter for the FrankEver FK-BV05 and the field named "Water consumed last". Compare the reported unit with the displayed value and check how similar water-consumption fields are handled. Done means this value is consistently reported in L, with a regression test if the existing device test structure supports it.
