Outputting victron mppt controller state

[bmeagle]

Hi guys

My off grid solar energizer is up and running now I want to gather some performance data.

Is there any rpi or similar alternatives to the official victron module that I could use to monitor this controller?

What's wrong with official Victron stuff? :-)

Just install the vedirect-interface debian package from the official repos and use it to monitor the relevant serial port. You will need a USB->vedirect cable. That takes the information and publishes it on dbus. You can either use vrmlogger to log to the VRM site, or write your own code to interface with dbus.

Of course you could just read the serial port continuously and parse the simple text input. Connection details is 8N1 at 19200 baud rate :-)

Thanks for pointing me to this cable, nothing wrong with this one, somehow I completely overlooked this.
Combined with a rpi and a bit of wifi I'll be able to keep tabs on things from afar, this installation is about 50m from the house.
