Hi! I'm John from Athens. I'm a professional Labview and Arduino developer. Let me assist you on this project. The sensor will send voltage to arduino, the latter to Esp and this in turn will post values on the internet via wifi. My proposal would be to use either ESP8266, or better ESP32, alone. No need for intermediate arduino. This setup is small enough so that it could be hosted on a rail case ([login to view URL]). I have great hands on experience with arduino, shields, sensors and variants. Also I have many projects on my file that were concluded under Non Disclosure Agreement due to academic or proprietary RnD purpose and are not displayed on Freelancer profile. Please feel free to contact me for further discussion. I'm currently occupied with two other arduino projects, so I will be free from Thursday or Friday. Kind regards, John Stratakos

Hello I have got your job posting “Create a smart energy meter” and I am very much interested to work in your project. I am a circuit designer and have more than 5 years experience of working with the Analog/Digital Electronics embedded systems(Arduino, Rasberry pi ,ARM processors ,PIC microcontrollers,Wireless boards,TFT Touch Displays,All types of sensors and actuators). i have done tons of similar projects So, I think you’ll find, I have the skills you’re looking for. For more on my skills and successfully finished projects, please have a look on my Profile and Portfolio. I have all the components available here with me so i will develop a working prototype according to your specifications and then send you the code and schematics so things will work for sure.I will remotely guide you and help you build the system on your side.I also offer unlimited revisions of the code and you get timely updates of the project. I am always available on Email and Skype. Please have a voice or video chat if necessary. I shall be available round the clock and able to start your project as soon as possible according to you. Thank you for your consideration, Best Regards, Haseeb Shafqat

My solution is - program ESP8266 ADC pin using Arduino IDE to read the current from SCT-013-000 and send directly to cloud via MQTT, no need Arduino Uno. As ESP8266 has only 1 ADC pin, you will need 3 separated module for 3 phases. In my solution, I am going to use WiFi Manager to enable user to configure the ESP8266 to connect to any WiFi network without hard-code. Notice that with your requirement, the SCT-013-000 just measures the current only. In order to measure the power, there is a better module such as PZEM-004T. This module take into account the voltage and current and the output is the power. ESP8266 will talk to PZEM-004T and submit the power directly to the cloud via WiFi network. There is a limitation of using PZEM-004T in 3 phases - you will still need 3 modules for 3 phases, however, for 220V the phase voltage will be 380V which will exceed the voltage of the PZEM-004T => you can only use this for 110V system. The cost in my proposal is for software development only. Additional cost is required for purchasing parts or shipment. I will also not be able to test with 3 phases.

I already build such kind of project where we capture data from pre build data and send it to our server where it store into database and show it on analytical web and application base platform. for more info please dm me will share its photo and if possible videos too. And yes I used MQTT protocol for data communicaton between app and device.
