Epsolar plugin for SignalK

[ddelorme]

I just finshed a little bit of python code that reads 1 to 4 epsolar tracer charge controllers. It works with the
the sk-plugin-python-demo.
The link to my plugin is Epsolar plugin.
I still has a few issues but it works.
It sends data to the SignalK server and has some configuration set up in the plugin config.
If it sees a epsolar device connected to the RPI via usb. It will configure, connect and send data.

well after a bit of a melt down here is the new link.... https://github.com/dmdelorme/sk-plugin-p...psolar.git

This serves also as an exsmple of a Signal K server plugin written in Python. There’s tons of Python for interfacing with sensors, so now you can embed that code in the server, including configuration in the server admin user interface. And the plugin can be distributed via the App store.

Its been a while since this thread was last posted but I am interested in connecting my EPSolar AN series MPPT controller to my RPi setup. Can it be used with the RPi4 and OPV2?

Thanks

yes but, I have an issue with the code and need to sit and do some rewriting. there is an issue with the config and some issues with the epsolar lib.

Thanks for the quick response. Perhaps you can post back when you have had time to sort it out.

howdy, just checking in if you've been able to work on this. I am just getting started getting EPSolar, RECBMS, WS500 data into Signal K and wherever there is already code available I love to use and study.

thanks .....

I'd like to try this, but I struggle with linux a bit. I have a Renogy Commander 60, which is basically an EPSolar iTracer 60. I found an EPSolar RS485-USB cable online and, after much messing around, was able to get the driver installed and the correct /dev/ttyXRUSB0 showing (although it took out some other stuff, which I'll fix later). But I do not understand how to check to see if info is coming through on this port or how to get it into SignalK.

So, I'm happy I found this thread, as it's the closest I've come to an answer yet.

I'm happy to try it out, just need guidance on how to get it in there.

Follow-up: I've been successful at getting my Renogy Commander connected to the Pi using the Exar driver for the E/ITracer usb cable using and interfacing it with Python using this respository https://github.com/devlpr/mpptCommander.

So the data is in there. Not to get that data into SignalK...

I solved this problem! Almost by accident, but solved it no less, using Node-Red.

I found this: https://github.com/AdamWelchUK/NodeRedEPEverDashboard

And was able to get the data out of the Renogy Commander 60. It took some messing around, but I was able to get pertinent data into SignalK using strategically placed "send-path-to-signalk" nodes and it all works!

If anyone is interested, I can send you the json codes from my set up to insert these, if needed. Uses Modbus and should work with various EPSolar-type chargers.
