Question

Hi Steve,

I found your tracer project, it seems old but maybe I you can help me?

If have a solar panel connected to my converter EPEVER Tracer2215BN: http://www.epsolarpv.com/en/index.php/Product/pro_content/id/573/am_id/136

It comes with a RJ45/RS485 pplug where you could use the optional MT50 display: http://www.epsolarpv.com/en/index.php/Product/pro_content/id/484/am_id/139

There is another option (which I use) to connect a litte box (eBox-Wifi-01) which can be used as an Wifi access point which can be used with an Android App:

http://www.epsolarpv.com/en/index.php/Product/pro_content/id/731/am_id/139

Everythings works as expected. There is a hack which makes the eBox act as a station in the local WLAN and it is possible to access the tracer from the EPEVER monitoring softare via a Netburner virtual com port. This also works but I want something else:

I want to access the tracer from my raspberry via the WLAN eBox and store/show the solar and battery values via html.

The virtual com port talks to the eBox in the local WLAN on port 8088 which atcs like a serial port (115200, 8,1,N).

So, there is a "serial port" at 192.168.1.15:8088

My question is:

How can I achieve a communication from my raspberry to the serial port of the eBox? Via http or some cgi-bin?

Second question: Since you seem to know the protocoll of the MT50, maybe I could just check if the values are valid for this device?

Or do I need some wireshark files to find out what is going on?

Anyway, it would be nice if you can find some time to point me in the "right" direction...

Best reagrds,

I can only help you with the protocol for the MT5
You find it here
Another VERY interesting and very complete publication about the MT5 you can find here BUT ... although it's in French, it's still very useful.
Hope you enjoy !

Thanks a lot for your information, I will check it out.
Although French maybe a problem but I will try and maybe translate.google.com will help me :-)

Meanwhile I found another source and I mange to get my raspberry reading data from the eBox device via socat.
See my comments here: toggio/PhpEpsolarTracer#14
Another interesting spot is the project of Adam Welch, check it out:

And here is a fully running system which stores and visualizes the tracer data:

All the best!!
