Review on 🔌 Power Meter Plug Upgraded with LCD Display, Improved Night Vision, Power Consumption Monitor for Energy Voltage Amps Electricity Usage, Overload Protection, 7 Energy Saving Display Modes, Watt Meter by Pete Brown

This device solved a problem others couldn't solve, it just needs to be made reliable. I wanted to know how often the drain pump turns on (not total time, how many times per period). The total kWh of this unit is measured in thousandths, which is accurate enough to measure a 20-second cycle or multiple cycles of 0.008 kWh each. So I can look at the counter and count. For reference, the timer counts the total time the device has been consuming power, not the total time the device itself has been plugged in. The timer is easy once you get the hang of it. It starts at 00:00, representing MM:SS, then returns at 59:59 to 00:00, representing HH:MM, then at 23:59 the day is incremented by 1 and the cycle repeats itself. They seem to have improved the instructions. also because it mentions how to reset the aggregated information by holding Function + Up. You just have to press the funny reset button when your device freezes. You can also set the maximum overload capacity. Mine was set to 3850(?) which is probably a pin of an internal circuit with a 220V capacity. They also describe how to set this, long press the function key, press the function key multiple times to show numbers, press up/down, press "cost" when done. I haven't set the cost, but you just press and hold 'cost' and then follow the procedure to set up the overload. The display has a very bright backlight that burns for a long time, they say 10m. In my setup I consider it plugged into an outlet about two meters off the ground and can be read from more than three meters away. Pretty unreadable without backlight. The only thing to do now is make it reliable. UPDATE: So the power failure alarm I connected to this unit (see separate review) uses some power, which is enough to register on the kWh screen but not enough to start the clock. This works great for my application as the pump cycle time is around 20 seconds and I can still tell how many times it has worked. So, intentional or not, it takes a certain amount of power consumption to start/stop the clock (they call it a clock, but it's technically a timer).
