Energy Monitor EPMC321-3*80A

This was perfectly easy to install (for the electrically skilled) in my residential, 3-phase panel. It has wiring long enough (but not more) to mount the computer somewhere near the bottom of a large panel, with the current sensors at the top (incoming power), and route the antenna outside.The Smartlife app saw it right away and added it without a hitch.You get live updates of power consumption (updated every 2-4 seconds as it seems). It's easy to tell how much is used by various consumers if you can switch them on and off.I can't tell how precise it is - hope the sensor wires are well shielded, and so on.

So far, Software is Junk, no detail graphs. Like my old TED Pro. If I installed it correctly, do to no help online, It is not accurate.

Did not work the way they said. Would not get wifi or connect to my phone.

Well this was just what i needed to keep track of my electricity bill, its quite easy to install (Requires certain knowledge of electricity) Pairing with Tuya was fast and straightforward. 10/10 Would recommend
