Solar panel monitor
#1
I have a victron smart solar with VEdirect to USB cable.  I found a script that is supposed to be used on the Raspberry but I am completely new to this system and cannot figure out how to integrate it.  I would like to use it for remote monitoring of battery state. There are several alternatives listed in Victron Open source page.

I am interested in this also -I have smart solar mppt and bmv712 battery monitor (which can use bluetooth) but using a direct cable to a MFD with openplotter would be excellent for many cases.

it tells how in the link you posted.
installation

Use the Signal K app store or install via NPM in the Signal K server root directory: npm install @signalk/vedirect-serial-usb
Usage

Set up the appropiate device on the settings page of this plugin in the Signal K server admin UI, for instance to /dev/ttyUSB0 and enable the plugin. Your VE.Direct data will be available in Signal K format via various clients and apps.

I remember feeling a bit overwhelmed when I used a Pi for a small home project. My approach was to take it step by step, beginning with simple Pi tutorials, then gradually working up to the script I needed.

Should be simple enough if you are already running openplotter: plug the VE direct into the RPI running signalk. Go to the SK app store and install the vedirect-serial-usb plug in and reboot. Then go into plugin settings, activate the plug in and set it up. Should be very straight forward.

As you normaly have a lot of Voltage going into SolarControllers (>50V) be carefull in using
only opto isolated VE-Direct Cables. Of course it is easy to connect the devices directly with cheap cables,
some spray water or moisture could destroy your pi and more.

I`ve just got the victron bluetooth app working. Mac address & advertising key now can be displayed in the android victron app. Doesn't seem to update that often but plenty useable & no wires. Pi is quite close to the smartMptt devices.

I had a similar challenge when I first attempted to use a Raspberry Pi for a home automation project. What worked for me was starting with the basics of Raspberry Pi operations, then moving on to understand the script itself. There are plenty of tutorials out there that can walk you through step by step.

And don’t hesitate to reach out to online communities—there are lots of forums and groups filled with people who have probably tackled similar projects.

As for remote monitoring of solar setups, having the right resources can make a world of difference. If you're looking for more information on solar generators and possibly integrating them with monitoring systems, you might find https://solargenerators.to to be a useful site. They cover a variety of topics that could help shed light on the technical aspects of what you're trying to achieve.

I'm having trouble finding the Mac address & advertising key on the android VictronConnect App to use with the SK bluetooth plugin.

Could you please run through how you got this working PaddyB!!

I have a VEdirect to USB cable connected to my BMV-700 which is working great but now have a MPPT solar charger via bluetooth which I would like info from on the Pi5.
