ChargeHA

ChargeHQ is a self-hosted app designed to provide feature parity with ChargeHQ.net while eliminating subscription costs. The application monitors solar production in real-time and intelligently manages EV charging schedules to maximize energy self-consumption. It offers advanced scheduling capabilities including day-of-week selection, per-vehicle amperage settings, configurable target charge limits, blockout schedules for peak tariff periods, and a live dashboard displaying energy flow diagrams with vehicle status cards.

The system supports multiple charging points simultaneously, each with independent schedules and vehicle assignment to apply state-of-charge and charge limit constraints. It includes reporting features such as tariff-aware cost tracking that records active electricity rates per reading period, along with historical statistics including day/month/year charts for energy production, consumption, and charging costs with detailed per-vehicle breakdowns.

ChargeHA utilizes a modular plugin architecture allowing developers to extend functionality without modifying core code. The tech stack includes Next.js, React, Node.js, and supports Docker deployment options. It provides real-time notifications via Telegram for critical events like charge start/stop, plug events, low solar conditions, energy outages, and errors.
