An open file format for power system wiring
OPN is an open file format for the wiring of power systems. The site shows public draft 0.1.0 with sample data for Victron Energy products. It has about 200 products, 1,155 SKUs and 121 wiring netlists. You can search a product and open its atlas, where you tap a port on the product artwork to see what connects there. Every diagram comes from plain text files, so tools can read and check the same wiring that people see.

You can view it as a graph, a list, bands or a DAG. You can filter by track, tier or region and show the path to any skill.

Live solar, battery and grid for one farm
This page shows the energy system at Wattles Rest, a farm with several Victron inverters, batteries, solar and a grid connection. You can see solar, battery, grid and load power as it happens, with the live electricity price and a running money ledger. A small publisher on the farm reads the Victron GX units and sends one snapshot every two seconds. It only reads: the energy control loop stays on the farm.

Which batteries work with Victron, and what they report
This guide shows which low-voltage and high-voltage batteries work with Victron Energy systems, and which features each battery sends to the system. It covers 39 makers and about 100 battery series. It is for installers and system designers. You can search by maker, compare features in one table and open a detail page for each battery. Where a fact is not documented yet, the guide says so. The layout is made for phones.

Live creek and river heights near Lismore
Creek Watch shows live river heights for Goolmangar Creek, the Wilsons River and 17 other Bureau of Meteorology gauges near Nimbin and Lismore, NSW. It reads the gauges every 10 minutes and keeps the history, with records back to 1880 at Lismore. Each gauge has a chart from 24 hours to 5 years and past flood peaks. You can set a phone push alert at your own height and add photos stamped with the river height. It is a family flood-watch tool, not an official warning service.
