WEM3050T WiFi Energy Meter, Smart Home Energy Monitor for Solar & Power Monitoring, Real-Time Electricity Usage, Compatible with Alexa (Multi-Phase Support)

Update the firmware if you have issues setting it up. For me i.76.058.8 works great. Once I got the new firmware installed everything worked perfectly! Set up MQTT and home assistant auto-configured all the sensors. The current clap wires are really long. I don't see that as a downside just be prepared to do some cable management. Nothing feels practically premium but it doesn't seem super cheap eithe. I would call the whole utilitarian. So far it's been accurate enough for my usage. It's reporting the same usage numbers as my electric company. The advantage is I can see each phase and there's a leftover clamp to monitor a specific circuit. Right now I'm tracking air handler usage but I eventually plan to track down a phantom draw.

Excelente producto, actualmente lo uso para saber cuanta energia demandamos y cuanto le inyecto a la red gracias a los paneles solares, cómo nota adicional mi red eléctrica es de dos fases divididades

Note that anything above 277, such as the common 280 or 285v WILL damage the unit. As most folks working with 480v delta, you are going to see a bit more than 277v L-N and it doesn't appear that this unit can handle this voltage. Given that nearly all North America "480v" is actually slightly above 277v, this mean you should NOT use this with a 480v system.

Excellent.

Trabaja muy bien

Pratique... mais attention il faut qu'il y ai les cables de chaque phase qui soit accessibles pour y passer les sondes.

Great product, quick delivery

Great product with exposed API allowing to build custom scripts. I bought 2 pieces. One was apparently used and returned back to Amazon by a previous buyer, so the SN was already registered and I could not add it to the cloud app. However the support team was very efficient and I could register the meter after a few hours. I recommend this product.

Ottimo misuratore preciso e completo a livello di software anche sul cloud con una piccola configurazione può andare.

Muito bom e eficiente
