Victron EVCS Solar Surplus Charging — Setup Guide

This Node-RED flow can be used to control a Victron EV Charging Station (EVCS) from solar surplus using Node-RED on Venus OS. The flow keeps the EVCS in Manual mode and adjusts charge current continuously based on grid meter readings, keeping a configurable buffer flowing to the grid to guarantee no grid power is used for charging.

An override allows forcing full-speed charging from the grid at any time, triggered either by the mode button on the EVCS display or by inject buttons in the Node-RED GUI.

# setup-transparent-bridge.sh
# Configure an OpenWrt device as a transparent bridge / AP.
#
# What this does:
#   - Installs required packages (curl, ca-certificates, wpad-mbedtls)
#   - Bridges all physical ethernet ports (WAN + LAN) into br-lan
#   - Disables routing, NAT, firewall, and DHCP server
#   - Makes the device a DHCP *client* so it gets a management IP from upstream
