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.
0.7.12
Consolidated 120 numbered Battery, EV and HVAC Flow cards into 25 selectable-slot cards for inputs, output commands and SoC requests. Existing numbered cards are deprecated, not removed: saved Flows retain their original arguments, tokens and behaviour. Updated Help and configuration references. Energy management, safety limits, planning and the slogan remain unchanged.

Quando...
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

HomeFlux EMS
Boiler warmed status is updated
The boolean token is Yes while HomeFlux still considers the boiler warmed after a completed heating cycle.

Novità
Versione 0.7.12 — Consolidated numbered Battery, EV and HVAC Flow cards into generic cards. All 31 slot selectors now dynamically offer only configured slots, including inputs, outputs, SoC requests and conditions. EV/HVAC names are shown; zero configured devices gives an empty selection. Numbered cards and previous fixed-dropdown cards remain deprecated but functional for existing Flows. Energy management, safety limits, planning and the slogan remain unchanged.
HomeFlux EMS
