Review: Works great and very DIY friendly - Very easy to fit, if you're in Europe just remember to switch off the main switch when fitting this, it's mains electricity after all. Only thing that took a while to figure out was which way to fit the clamp, figured out eventually and it's been working ever since with no problems. Good value for money and great if you have home assistant to monitor electricity usage with no outside servers
Review: Great starter for energy monitoring - This item is about as simple and easy to install as I have seen in a long time. The in box instructions are limited, but go to the website and the help there is abundant. some of the information may be disjointed, but with this item setup is pretty straight forward for those that do this stuff. If you are new to this, take time to read all the manuals. You are wiring it to electricity and it will hurt you if not kill you. not to mention burn up electronics. Yes it is AC, but polarity counts. hooking up to WiFi was easy, the instructions were actually helpful. If you get the three phase one for single phase use. it is a little more complicated. it require attention to details.

## Questions & Answers

**Q: Will this work with local wifi and smart device..with NO internet ??  Direct via wifi to app ??.... no cloud service mandatory... off grid use ??**
A: Yes, it can work with local wifi with NO internet. Please refer to https://www.iammeter.com/docs/local-monitoring. You can also upload the data to your own server, please refer to https://www.iammeter.com/docs/own-system. Please let me know if you have any further questions!

**Q: Is there anyway to monitor both legs on a single phase circuit?**
A: Buy two units install one on the phase and one on the neutral. You can only monitor one wire with one unit as only 1x CT can be connected. Why would you want to monitor the neutral anyway? Or purchase the three phase unit and just us 2x CT’s. Hope this helps.

**Q: L1 to n =120v, l2 to n=120v, l1 to l2 =240v (typical usa residential service)**
A: Hi:
I see, it is the single phase 3wires system.
You can use one 3phase meter(WEM3080T) to monitor it because the 3phase meter also supports split-phase usage.
You can also use the cost-effective method, which only needs one single-phase energy meter.

**Q: Hola, funciona en Chile que utilizamos 50hz?**
A: El equipo funciona bien con nuestros 50 hz y 220 V ya que en su especificación indica 240 V. Como los parámetros eléctricos en ondas sinusoidales se miden en valores RMS o efectivos, no es perceptible la diferencia si el fabricante lo calibro para 60 hz. En mi caso el equipo está funcionando desde hace bastante tiempo y es una muy buena referencia para comparar con la cuenta que nos envía la compañía eléctrica. Su interfaz es muy grafica, se pueden ver valores de potencia instantánea, Kwh diarios, mensuales o anuales, positivos o negativos si la inyección es mayor.
