Alexa skill command - CurrentTemperature

HI. I have set up OH2-myopenhab-Alexa and have an arbitrary item. I see it in Alexa app! All connections are OK. It is not part of thermostat.

Number WaterConsumption "Cold Water" (gSmurfs) [ "CurrentTemperature" ] { channel="some_fancy_binding" }

In alexa app it is presented as “Cold Water”.

What do I say to Alexa to get the value?
“Alexa, what is the cold water temperature?” - Not working.
