Turning MPPT SCC on/off via VEDirect

Hello,


I have an 100/30 SCC, connected with a VEDirect - USB cable to a raspberry pi. I can read information from the SCC, such as panel voltage, battery voltage, history etc, but I didn't find a way to turn the charger on or off, or changing settings.


Does anyone know a way?


Thanks!

P.S. I can't run VenusOS on the pi as it controls other sensors in my installation. The pi does have bluetooth, so if an equivalent solution via bluetooth exists that would work as well.

Why would you want to turn your mppt off?

Normally I wouldn't, but it runs in a remote location and I want to have this option in case of emergency (e.g. fire, flood etc).

How would shutting down your mppt be beneficial should the installation be impacted by fire or flood?

You can disable it via bluetooth or the internet (requires a gx or similar) using the victron connect app.

Thank you for your answer, but I couldn't find a way to run the victron connect app on rpi (arm). Is there one?

So you would need a pi or the like with venus os and you need internet access to VRM. You could then remotely from your phone disable the charger from the app.

Without internet access and a gx/venus, you're a little stuck.

You can disable the charger also via node red automation, but this too requires a venus with the large image.

You need a wired connection to the Cerbo /Venus (raspberrypi), you need a Ve.Direct to USB cable, so the Venus can communicate to the MPPT controller, BT is not an option.

Thanks all for your answers, they are all valid options. I solved it by using usbip on the pi, which exposes the USB connected MPPT to an x86 machine running linux, where I can run the Victron Connect app.
