Energy Node

Energy monitoring and automation for a remote solar/battery site on a tiny Raspberry Pi, works with or without HA.

Servicefreeglobal

Energy Node is a free, open-source energy monitoring and automation system for remote solar/battery sites - a barn, workshop, or second property - too far or too poorly connected for a home Home Assistant instance to poll reliably. It runs standalone on a tiny Raspberry Pi at the site, doing local polling, rules, and a dashboard, and mirrors data home over a Tailscale MQTT bridge when a link is available.
