Ultimate EMS

Ultimate 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. Key features: - Works with your existing Homey apps — no custom drivers needed - Multi-inverter support with per-phase surplus tracking (L1/L2/L3) - EV charging via Zaptec, Easee, Tesla and other supported chargers - EV departure planning with target SoC and solar-priority logic - Heat pump and air conditioning control with seasonal heating/cooling switching - PV curtailment for Growatt inverters (zero-export / export limit) - Dynamic tariff support: Tibber, PBTH/Enever and other price providers - Live dashboard widgets for EV status and PV fleet overview

새로운 기능

버전 2.4.9 — Fixed: for chargers that don't report whether a vehicle is plugged in at all (e.g. the Alfen ACE, community app), the EV widget could confidently show "car not connected" while a car was actually plugged in and just not drawing power yet — it was mistaking its own last on/off command for a real sensor reading. It now shows a neutral "status unknown" instead for this specific case; regular chargers with a real connection signal are unaffected. New: when an Alfen ACE charger is detected, the app now automatically switches off that charger's own built-in solar-charging mode, so Ultimate EMS becomes the sole controller instead of two solar-following logics fighting over the same charger (this was causing some Alfen ACE installs to sit at "waiting for power" indefinitely). Also: added recognition for several newly seen device types on the fleet (Deye inverters, extra MELCloud/Nibe/Stiebel/LG ThinQ heat pump variants, a CHHV zone thermostat, the official Zendure app, and Skoda/Smart EVs), so they now show up correctly labeled in bug reports and the portal instead of as unknown devices.
