Hello,   
      
   I want to log energy consumption of a water kettle. On 24x7 and used   
   through the year. Minimum resolution should be 10 seconds. I don’t really   
   need absolute values. Only want to know if lowering temperature for a   
   period is efficient.   
      
   Energy necessary to heat water is easy to find. On Wolfram Alpha as   
   example. Unknown is the initial temperature. I do have a temperature sensor   
   accurate in the 30°-99°C  range.   
      
   Another option is a smart plug. But adds friction through proprietary   
   interfaces. Also found a scientific article casting doubts about accuracy   
   of consumer devices.   
      
   Many articles in scientific literature consider water kettles energy   
   consumption. As example “Life cycle environmental evaluation of kettles:   
   Recommendations for the development of eco-design regulations in the   
   European Union”. Scanning them haven’t found what I need.   
      
   Thanks for sharing.
