Hello All,

I am monitoring HP Procurve switch , one of the monitoring object is the temperature “hpSystemAirCurrentTemp” first the data got in hex then i used

overrides:
      
      hpSystemAirCurrentTemp:
        type: DisplayString

but still i cant work with it since its display for example 27C , my question is there way to omit the “C” , so only the decimal stays?

Please advice

Thanks
