Ultimate EMS

Home EMS turns your Homey Pro into a full-featured energy management system. It intelligently coordinates your solar panels, home battery, EV charger and heat pumps to maximise self-consumption and minimise energy costs. Every evening the EMS calculates a detailed plan for the next day based on the weather forecast, expected solar production and your energy prices. During the day it follows this plan in real-time, adjusting automatically when clouds roll in or your energy use changes. For Tesla owners, the Wall Connector is read directly over your local network for precise, real-time charge control without cloud delays or API rate limits.

EV Charging

Was ist neu?

Version 1.6.27 — New: zero export mode — when enabled, the EMS uses the P1 meter as a closed-loop feedback signal to prevent grid export. The home battery absorbs all surplus above the configured buffer (zero_export_min_surplus_w). EV charging start/stop thresholds are shifted upward by the same buffer so the battery loop always has headroom. Solar grid assist is suppressed in zero export mode. New: PV curtailment detection — the EMS now compares actual inverter output against the Open-Meteo forecast for the current hour. If actual production is below 80% of forecast (and forecast exceeds 500W), the state is flagged as pvCurtailing. This tells the EMS that virtual surplus is available (the inverter will ramp up when a load starts). New: expanded bug report — now includes battery adapter details, thermostat device list, PV curtailment snapshot (ratio actual/expected), full today's PV hourly curve, EV zero export thresholds, and internal EMS config summary.
