What power level? Up to 2000 watts?
I am using "SonSoff S31 Plug with power monitoring". Form my PC or phone I can see line voltage, current and power. I also can turn on or off the power.
There are two versions so make sure you get the "Plug with power monitoring".
It is only good to 15A! Link
I can highly recommend Shelly, and the Shelly Plus 1 PM as an excellent option. It is like the Sonoff but a lot friendlier for makers and product integration, and it is better built. A bit more expensive, but I have found it worth the difference. It also has apps for Android and iOS in addition to it's API and native MQTT support which is brilliant.
Hello guys thank you for your answers, i want to build it for a College project , that's the reason why I'm planning to use an SBC and Azure IoT and the adapters, i have seen multiple projects and they do it by connecting from the
Transformer --> AC to DC converter --> 200V to a lower volt converter --> Arduino --> Wifi Module --> Cloud Service
If you plan to use the NodeMCU ESP8266 the Arduino is redundant. Just us the 8266 but your problem is going to be how to monitor the consumption of the entire premises.
The papers you linked don't seem very good and the methods they are using are less than ideal. You really need a large current transformer that can be placed (passively) on the feed to the breaker panel. But there is a serious safety concern working with such high voltages and currents.
Hey man, first of all i want to Thank you a lot for the support.
Yes we have one, but the meetings are on wenesday, my group needs to have a model that let the normal users see the Energy consumption that they have on their residentials.
Can you recommend us any methods or good guides to accomplish that?
