A bit more expensive but it works the same PZEM 061

If you want to get a better view of where the most of the electric bill is going, then this kind of meter is a must. Initially the meter was warming up a little bit when put on 240V because the original internal power supply is working to as little as 26V AC. The 1uF capacitor is too much for 240V. I had to reduce-it to 0.22uF to have no heat at all. This should take care of some issues that can develop over time with thermal stress, some reported their meter died. There is no need to keep the back screen light on since the view is so clear for this particular display. Overall very happy with my purchase.
