Teardrops n Tiny Travel Trailers

bdosborn,

Nice graph. How did you do that? Did the capability to graph come with your battery monitor or did you purchase some other type of software?

I used a Raspberry Pi to network my Victron Battery monitor and the Victron PV charge controller. It has the same function as the Victron Color Control GX Monitor ($500!). Then you can link to the pi to the Victron VRM Portal (free account) and display the logs from the pi on their website. I can check on my trailer anywhere I have a web browser. I get emails if the battery voltage goes low or high. Sounds complicated but it was one of the easier Raspberry Pi setups I've done. Cheap insurance for my expensive LiFePo4 battery.

The Victron software is free to use. No programming, just download the image and install it on the Pi:

You have to buy the VE direct cables, which are kind of spendy. These connect the Victron devices to the Pi USB ports:

Thank you for the expansive explanation. I will look further into this technology.
