HomeFlux EMS
Your energy, managed differently
Your energy, managed differently
HomeFlux EMS coordinates batteries, solar production and flexible loads around the energy contract you actually use. It supports dynamic pricing, but is equally designed for fixed contracts with two or more time-of-use tariff periods such as peak/off-peak and multi-rate schedules.
HomeFlux combines tariff periods, PV forecasts, battery reserve, self-consumption, grid limits and user priorities in one control strategy. Hardware integrations remain independent through explicit Homey Flow cards, while Peak Guard remains a hard safety layer.
The goal: increase useful self-consumption, buy energy at the right moments, protect reserve for later and avoid unnecessary grid peaks.
Use the optional HomeFlux EMS device for quick control/status and add the EMS status and Savings widgets to keep planning, ownership and cost impact visible on your Homey dashboard.
Autotune can auto-manage individually approved parameters only above a configurable confidence threshold and within user-defined limits. Savings also includes PV export/feed-in; positive export prices are compensation, negative prices are injection costs.
Each EV can stop at its SoC target (default) or continue according to configured tariff and PV preferences. Manual session stops and kWh targets still stop charging.

언제...
Fires when battery SoC spread keeps increasing while balancing is actively controlling the batteries.
HomeFlux EMS
Battery commands are updated
Fires when HomeFlux EMS publishes a new set of battery power commands.
HomeFlux EMS
New battery setpoint calculated
Fires when HomeFlux EMS calculates a different battery setpoint, before the minimum command interval decides when it may be published. It stays silent while Hybrid EMS has delegated battery control to an external EMS.
HomeFlux EMS
Boiler power command is updated
Use the boolean token to switch the boiler or store its current HomeFlux state in a Logic variable.
HomeFlux EMS
Boiler warmed status is updated
The boolean token is Yes while HomeFlux still considers the boiler warmed after a completed heating cycle.
HomeFlux EMS
Charge plan is updated
Fires when HomeFlux decides or changes the overnight charge plan. Use the Charge plan token with Homey's standard Logic action to write it to a text variable.
HomeFlux EMS
EMS status changed
Fires when the compact HomeFlux EMS status line changes.
HomeFlux EMS

HomeFlux EMS
Get Category for the last Number Period as Output · EV EV (for EV categories)
Uses existing daily records, including today so far. Months/years are rolling calendar periods. Missing history is not backfilled; check available days and complete coverage. Value is realized savings or cost for cost categories. PV stored has no realized value yet (value available = no). Total energy counts direct PV use/export and battery delivery once. Applying this card does not change control. The Selected result token follows your output choice: kWh, kWh with price or price only. Monetary amounts use your configured currency. EV categories use existing Insights daydata. EV selection only affects EV categories; existing Flows default to all EVs. No EV data is distinct from recorded zero. Solar kilometres and solar share are separate tokens. Known costs may be incomplete; check EV data complete. Solar charging cost is forgone feed-in revenue; battery energy stays unknown without proof.

HomeFlux EMS
Read Price source prices JSON Prices JSON for Period
Send a timestamped JSON curve or a numeric price array, up to 120 hours ahead. For numeric arrays select the same period as the provider; resolution follows the dynamic contract. Timestamped data ignores Period. Source labels use your configured names. Renaming a source does not change its identity.

HomeFlux EMS
EV: Energy needed (kWh) kWh needed by Deadline (HH:mm) · guaranteed: Guarantee target?
Sets a persistent minimum energy target for the selected EV. It remains active until another EV target is submitted or the planning override is cleared. HomeFlux tracks delivered energy from the reported charge current. Guarantee = No keeps deadline charging on configured favourable tariffs/PV; Yes may use any tariff when required to secure the minimum. Peak Guard always remains absolute. Only slots within the saved device count are offered. At count 0 the list is empty. The session completes when measured charging current has delivered the requested kWh. Pauses do not reset the remaining energy. The target survives app/Homey restarts. Only Clear EV planning removes the override; a new Flow target replaces it. Zero kWh is a persistent completed target. A restart with the EV still connected preserves the remaining energy; an observed disconnect/reconnect starts a new counting session.
HomeFlux EMS
EV override for one session: EV 1 operating mode
Temporarily use the selected operating mode for the selected EV for one connection session. If the selected EV is already connected, the override ends when it disconnects. If it is disconnected, the override waits for the next connect → disconnect cycle. The configured mode for the selected EV is never overwritten. Only slots within the saved device count are offered. At count 0 the list is empty.
HomeFlux EMS
EV: minimum Minimum SoC (%)% SoC by Deadline (HH:mm) · guaranteed: Guarantee target?
Sets a persistent minimum SoC and deadline for the selected EV. It remains active until another EV target is submitted or the planning override is cleared. Guarantee = No tries to secure the minimum on configured favourable tariffs/PV; Yes may use any tariff when required. After fresh SoC reaches the target, the per-EV setting selects stopping or continuing with normal tariff/PV preferences. Stopping is the default. Reconnecting arms the target again. Peak Guard always remains absolute. Only slots within the saved device count are offered. At count 0 the list is empty. The target survives app/Homey restarts. Only Clear EV planning removes the override; a new Flow target replaces it.

새로운 기능
버전 1.2.6 — Added a Savings category Flow action with totals, rolling day/week/month/year periods and a choice of kWh, kWh with price or price only. Optional night SoC hysteresis and a restart-safe 00:00–02:00 PV forecast median hold reduce night charging changes. Autotune battery output intervals are limited to 4–17 seconds, with evidence-based grid-band recommendations centred on zero and sized for battery power steps. The same Flow action also reads EV Insights for all EVs or EV 1–4, including source energy, known costs, estimated solar savings and solar-kilometre tokens, with explicit data availability.
