Sonoff pow r2 wrong readings

I attached a screenshot of my pow r2. Readings indicate voltage at 225.39V, current at 0.15A and power at 14.2W.  But P=UxI=225.39*0.15=33.8 (W). Voltage is correct, so which of the other two is wrong? Same problem in the screenshot from the manual of pow r2.

Same here, readings are 139W, 1.25A and 238V.

My science teacher will not approve of Itead science.

Update - I've used an SDM120 Modbus Single Phase Multifunction Energy Meter to verify Sonoff Pow R2 readings and got approx same values - Big question now remains what is happening to Ohm's Law since this is so not correct.

First, sorry for my bad English. I have not all words to describe.
P=UxI is for direct current, here you are in alternatic current. So it needs to be P=UxIxcos(phi). Please read about phase shift.
In your circuit are inductive or capacitive, but not only ohm, devices.
