Who wants to play with my Victron & Schneider?

My installation in Paarl has finally been commissioned on Friday past after Muni installed their Smart Meter. The Victron is feeding one phase and two Schneiders are feeding the other two phases with excess from panels going back to the Munie.

The next step is now to start monitoring these units and reporting the outputs. I have a laptop I can dedicate so I need somebody that can supply me with all the correct cables and come and visit me and install the software and get the monitoring up and running and reporting on the web.

I will pay for your consulting services and of course the cables. Email me on [email protected]

Eish, now that I have a day job again, I have to do these things on the weekend, and do you know how much paper work it is to get permission from the minister of internal affairs to go out on weekends? :-P I'd love to play with it, but I can't commit serious time to it :-(

How do you access the Rpi? Is it via a WiFi connect pc or does it need its own screen and keyboard?

It depends. First prize is to plug it into your internet connection with an ethernet cable. Second prize (this is how I run it) is you plug in a wifi USB dongle and configure it for your wireless network.

How you access it beyond that depends on what you run on it. I run a linux-based image on mine (Raspbian Jessie), so I use ssh (secure shell) to log into it. This is the de facto Unix standard for remote connections, but you have to be comfortable in a shell*.

If you run windows on it, then you can use vnc or some kind of remote desktop technology. Then what jdp says applies: OpenGL and other direct rendering tech doesn't work. That stuff often doesn't even work if you plug in a second monitor/projector. Fwiw, on Linux with X** the same applies, direct rendering doesn't work on secondary monitors (opengl, xv, directfb, etc).

* A shell is what windows people might know as a "command interpreter", and there's only one for windows, ye olde command.com or cmd.exe. Don't be fooled, the shell programs on unix systems (bash, csh, ksh, etc) are miles ahead of anything on windows. Has been since 1984.

** Sometimes people talk of "X windows" but that is wrong. It is simply called X. X is client-server... also since the 80s, which means your application need not run on the same system where the display lives.

Of course you can also access it via keyboard and screen. Plug in usb keyboard, snap in hdmi screen. That's how we configure the network details first time round...

Or if you have another linux system (assuming you run Linux on the pi), you can remove the sd-card, plug it into that other system, and edit the files directly. Must be Linux unfortunately, the filesystem used is ext4. Which btw is a very nice journalling filesystem which also beats the pants off anything Microsoft... since the 90s. :-P

Also a problem for me at this stage and not sure if I can get around it is that if you use VNC you can not see the desktop like when you use Teamviewer on windows. VNC creats a new virtual desktop and what ever you run in there will not show on the desktop and you can not see what is going on, on the desktop. So if you have a touch screen and you start software on it you can not interact with it via VNC.

BTW I got VNC working to see the desktop not a new session. But you can still not see any OpenGL or accelerated graphics via VNC. It still does do what I need it to do. Works very well. Will give a demo of what I am working on when it is done. Will use the same stuff for the solar project.
