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

Versjon 2.3.1 — Fix: an hourly price spike (typically around midnight) could still show up in the Today/Tomorrow price widget even after a previous fix, when the affected hour never received a real price update at all — the earlier fix stopped new bad estimates from forming but couldn't correct one that was already stuck from before. A safety limit now caps how far any estimated hour's price can be scaled relative to the day's average, so a single stuck or missing hour can no longer show a wildly inflated (or deflated) price, and this also immediately corrects any such value left over from before this update. New: recognised several more devices by name, including the Victron Energy ecosystem (battery, solar charger, PV inverter, grid meter — already worked for monitoring; the Cerbo/Venus GX hub's own charge/discharge control is not yet wired up), a second Marstek battery app, the Nibe heat pump via its official myUplink app, Sigenergy batteries/inverters, Panasonic Aquarea, a second Tado app for air conditioners, and an LG air conditioner app. Fix: an EV tracked through Volkswagen's We Connect app could have been mistaken for a home battery in device detection, due to sharing a capability with real batteries — it's now correctly excluded, matching how Tesla and other EVs are already handled.
