Intelligent energy management for solar, battery, EV and heat pump
경고! 이 앱이 제대로 작동하지 않을 수 있습니다.

이 앱을 설치할 때는 각별히 주의하세요.
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

Ultimate EMS
EMS mode changed
Triggers when the EMS switches to a different operating mode.
Ultimate EMS
Priority 1 not fully achievable tomorrow
Triggers when the forecast shows insufficient solar energy to cover all priority 1 loads.
Ultimate EMS
EV ready for departure
Triggers when the EV has reached the target SoC for a planned trip.
Ultimate EMS
Battery below minimum SoC
Triggers when the battery drops below the configured minimum state of charge.
Ultimate EMS
Dump load activated
Triggers when all priority 1 and 2 devices are satisfied and surplus energy is available.
Ultimate EMS
Dump load deactivated
Triggers when the solar surplus drops and dump loads are turned off.
Ultimate EMS
EMS wants to set EV charge current
Fires every time the EMS calculates a new target charge current. Connect this to the 'Set charge current' action of your EV app.
Ultimate EMS
EMS wants to start or stop EV charging
Fires when the EMS starts or stops charging. Connect to your EV app's start/stop action.
Ultimate EMS
EMS wants to start EV charging
Fires when the EMS wants to start charging. Connect to your EV app's start charging action.
Ultimate EMS
EMS wants to stop EV charging
Fires when the EMS wants to stop charging. Connect to your EV app's stop charging action.
Ultimate EMS
Heat pump switched mode
Triggers once per day when the EMS switches the heat pump between heating and cooling based on the weather forecast.

새로운 기능
버전 1.8.2 — Fix: the day-ahead planner could schedule an EV grid-charge block that overlaps a configured peak-hour blocking window (e.g. a cheap price window ending inside the default 17-21 evening peak) — the realtime controller then silently skipped that part of the block since it blocks all EV charging during peak hours, regardless of source. Found via a forum bug report where the plan showed the EV charging at 17:00 while the live status that same hour showed it blocked. The planner now places EV blocks around peak windows instead of through them, shifting or splitting as needed. Changed: the app's support link now points to the Homey Community forum topic instead of GitHub issues.
