Review on Efergy 4 0 Wireless Electricity Monitor by James Nedumaran

The kWh readings are more constant at 0.50-0.60 kWh than the actual consumption. When all appliances, TVs, fans, etc. are off when 0.50 - 0.60 kWh is registered. Compared to the consumption meter, it shows a daily consumption of +7.0 to 10.0 kWh per day. The disadvantage of this point is that you cannot set the monthly usage day to the utility billing date. I've tried all sorts of ways to contact the seller to no avail. The meter shows more than the actual consumption compared to the electricity meter reading and the monthly bill from the energy company with an error of 40-60%. The actual consumption of the 330 kWh meter shows around 550 kWh. I do not recommend this item.
