This meter works very well and it does not require the internet. I was able to integrate it with my 100% custom system in just one evening. I will post code later along with updates on the device itself. It looks very well built. I hope it does not break!The only thing I don't like so far is that I don't seem to be able to change the sampling/reporting rate. I wish I could get data faster than once per minute. I have sent support an email and hope to get a response soon. Fingers crossed.Update: It turns out I didnt have to wait much at all for a response from the support team. They quickly returned my email within a few hours with a solution. With a firmware update I was able to set the update interval! Hands down this is a great device that gives you full control of your data!UPDATE (1/8/23): O ended up buying a second one to monitor more things. The first one is still working strong! For you reference the code I used to log data on my own server is below:<?php$input=file_get_contents('php://input');$data=json_decode($input);$datas=$data->{'Datas'};$phA=$datas[0];$phB=$datas[1];$phC=$datas[2];$vPhA=$phA[0]; $iPhA=$phA[1]; $pPhA=$phA[2]; $pfPhA=$phA[6];$vPhB=$phB[0]; $iPhB=$phB[1]; $pPhB=$phB[2]; $pfPhB=$phB[6];$vPhC=$phC[0]; $iPhC=$phC[1]; $pPhC=$phC[2]; $pfPhC=$phC[6];$sql="insert into meter values(now(), $vPhA, $iPhA, $pPhA, $pfPhA, $vPhB, $iPhB, $pPhB, $pfPhB, $vPhC, $iPhC, $pPhC, $pfPhC)";$conn=new mysqli("localhost", "user", "password", "meter");if($conn->connect_error) {die("Connection failed: ". $conn->connect_error);}if($conn->query($sql) === FALSE) {die("Query error: " . $conn->error);}?>

Want to have power data integrated within you own app? This one will let you, not a walled garden. Can be setup to post its JSON payload directly to a REST endpoint...or you can poll it at /monitorjson. (And the latest firmware handles remote SSL fine, just make sure you're on the newer V1.75.46 version.) Other options either involve a lot of DIY electronics, or hacking your way into some service that doesn't want to share its data. Also appears quite accurate. REST POSTs arrive about every 6 seconds.Note if you want the WiFi antenna port routed inside your DIN enclosure (coming out the top) like the WEM3080, these just snap apart, and its very easy to drill a new hole and move the connector to the top vs front.Together the 4 channels of a WEM3080 + WEM3080T work great to monitor main power plus a 240v split circuit. Together they fit well in the HT-8 DIN boxes, or for just this alone the HT-5.

Excelente producto

it's all Chinese stuff and data is pushed to Chinese portals, but you can get really nice diagrams and cost reports. Its worth to install if you have solar power or if you just want to know what devices consume power in your house. Biggest advantage of this device is that allows you to integrate with custom applications. It expose information via internal HTTP API allowing to pull data in JSON format. No need to integrate with China cloud if you don't want to leaving value in customized IoT solutions e.g. putting stuff in zabbix. I'm using zabbix to get statistics. One of the drawbacks is that current may leak cross phases, but probably due to fact that is use coil loops on each wire that may interfere with each other, but you will not overcome this easly. I get power <0W like I would have solar panels, but current leak is very low, i just ignore that.

I bought this product to monitor electric use in my house. I wanted to monitor both phases of my 240VAC main box. I don't use the third phase at all of this device. Set-up was a bit challenging but once I got it up and operating it has been great. I have subsequently purchased two, single-phase models to monitor additional 240V heat pumps in my house. These were easier to setup (probably due to my having gone through the setup process already).I have contacted tech support 3-4 times now and they have been amazingly responsive and helpful. This is the biggest plus -- I have some prior experience with another brand of energy monitor and did not enjoy such good tech support. I access my data both using the phone app and also with my pc on the web. Soon I hope to connect to them using Home Assistant.

Me agrado que tenga una web dónde se puede consultar en todo momento varios parámetros. Los desarrolladores actualizan el firmware de manera constante dotandole de mayores características. Es fácil de instalar. Lo recomiendo.

I own 6 of these. I've constructed my own monitoring system with InnoDB, NodeRed, MQTT, etc. I'll add more to my farm. If you know what you're doing, this thing is great!

Good product and very fast delivery
