Ultimate EMS
Intelligent energy management for solar, battery, EV and heat pump
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

Nowości
Wersja 1.7.2 — Fixed: on days with broadly high prices, the EMS could classify the "least bad" hours as cheap and start EV/grid charging even though the price source's own tile showed it as expensive (reported on the forum). isCheap is now gated with an absolute price ceiling on top of the existing relative rank/window methods, applied consistently regardless of price source (Power by the Hour, Tibber, or Elecz). Settings page: clarified several confusing labels and hints (EV solar start threshold, load-balancing sections), removed internal code references from user-facing text, and moved Zero export to the Grid connection section since it also involves the home battery, not just solar.
