    I am using 2-ton Diken AC. AC was not in use but last week 3 hours run without any issue. I found the Overload protection feature which is not available with any Smart life products. this costly than Pow R2 but i am not worried now because this is 5500watt. I hope will get a future discount for this feedback

    Ordered on 23/10/2021. Received 26/10/2021. delivery is very fast. device on/off function working fine. Timer function working fine. However power measurement is not good. Big difference in unit recorded with respect to class 1 energy meter. After sales support is very poor. I have sent more than 10 mails, No reply received till date. So please do not plan this device for power monitoring which will not give true value.

      Sorry for the late reply
      For your questions:
      1.Formula for Power(Watt)=Voltage(V) x Current(A)
      Voltage = 234.86V
      Current = 5.31A
      Then power P=V x C= 234.86 x 5.31=1247.10
      how ever in screenshot power is 314.10W
      1247.1 W is Apparent Power
      314.1 W is Real Power
      you can refer to this link for further info:
      When the load is inductive, the measured Real Power will be much smaller than the Apparent Power

      I have enclosed scrren shot from sofar solar inverter.
      here Voltage 144.80V ,Current 1.70A then Power 246.16
      which shows P=V*C 144.8×1.70 =246.16
      Because here you use the DC connect.
