Please I am looking into getting a DC Watt meter for my solar system.
Something that I would ideally place between my solar panels & controller.
I would need options for
1) An ordinary meter
2) One with logging capabilities
3) One with the ability to view my production data online
Your contributions are greatly appreciated
 
Raspberry pi hooked up to any meter will do the trick. Of course you can use ESP and others too.

Question is if you want to make it your self or not?

Raspberry pi with some AD and shunt and you got what you want above.

Thanks Daromer. I would really like to go the Raspberry PI way. I have heard so much about it and I don't like passing up an opportunity to learn something new.
Wha naterialst would I need to get started on R-Pi and where can I find learning material.

BTW what does AD & ESP mean?
 
ESP8266 or ESP32 is a microcomputer you could say. It has wifi and can do plenty of stuff.

Ad = Analog to digital converter. Its needed for converting lets say shunt voltage to readable values for the PI.

If you havent worked with such things before you need to know that it will be a steap learning curve. I suggest to youtube it some :)

Thanks a bunch Daromer.
I am willing to jump into it irrespective of how steep the learning curve is.
I already know how to write codes so I guess the electronic part may be the only difficult part.
