      Hi

      I live in Australia (Voltage = 230V) and the Emporia app is showing the voltage correctly (~231V)  AND is showing the current correctly (say 10Amps).

      However when I change the unit of measurement to Watts it does not do the correct calculation (231V * 10A = 2310W). Instead it gives me a reading approximately half of what it should be.

      I suspect it is using a fixed 110V or 120V as the basis for calculting the Watts despite having both the correct voltage and current available to it. Now I realise I can configure a multiplier for each circuit but if I put a multiplier of 2 then it doubles the displayed voltage.

      Surely the app can do a simple wattage calculation correctly W = V * I when it has the correct V and I available (seems like a 5m fix)? Is this a known defect that wil be fixed? What voltage is it assume in the calculation (110V or 120V) – so I can get the multiplier correct until such times as the app is fixed?

      If I am using something incorrect please point it out as it could just be me.
