What is EEBus?

EEBus is a communication protocol focused on energy management applications for major appliances, heating and ventilation systems, and electromobility. It enables intelligent communication between household appliances, electric vehicles, heat pumps, energy generators, storage systems, energy management systems (EMS), and the smart meter gateway. EEBus acts as a common language that connects a wide variety of electrical building components across different sectors.

EEBUS communication takes place over a network, whether wired or via Wi-Fi. Typically, a central Home Energy Management System (HEMS) communicates via EEBUS with all connected components, such as the heat pump, wallbox, or smart meter gateway. Alternatively, EEBUS-enabled devices can communicate directly with the smart meter gateway to implement power limitations in accordance with Section 14a. Particular emphasis is placed on IT security to prevent unauthorized access. EEBUS is based on defined use cases that govern data exchange between various components and specify the behavior of participants in specific scenarios. One example is power limitation under Section 14a (LPC).

A detailed overview of the use cases can be found on the EEBUS website.

Power Limitation (LPC)

• Objective: Protection of local grid stability

Mechanism: Ensuring the heat pump complies with the power limitation value received from the smart meter gateway (SMGW) or a third-party EMS (LPC takes priority over comfort)

Power Monitoring (MPC)

• Objective: Transparency regarding electricity generation and consumption

Mechanism:Forwarding the heat pump's electricity consumption value to the Smart Meter Gateway (SMGW) or a third-party Energy Management System (EMS)

Optimization of PV self-consumption (OHPCF)

• Objective: Optimization of PV self-consumption using the heat pump

Mechanism: Transmission of a power sequence to the EMS, which controls the available flexibility (based on PV surplus)

Matter is the open, cross-manufacturer connectivity standard for the connected home—developed and supported by over 600 companies, including Apple, Google, Amazon, Samsung, and Bosch. It ensures that devices from different manufacturers communicate reliably with one another, whether the focus is on convenience, security, or energy efficiency.

• One standard, many devices – Whether it’s lighting, sensors, wallboxes, heat pumps, or solar systems: Matter-certified devices speak the same language and work together seamlessly.

• Smart energy management – ​​Matter enables holistic control of household energy flows: solar systems, battery storage, heat pumps, water heaters, and EV charging stations coordinate automatically—based on electricity prices, self-consumption, and grid load.

• Simple setup – Scan the QR code, connect the device, and you’re done. No need for separate apps or accounts for each manufacturer. Platform freedom – Control all Matter devices via the platform of your choice—Apple Home, Google Home, Amazon Alexa, or specialized home energy management systems (HEMS).

• Security & privacy – Encryption and local data processing are built into the standard. Your data stays in your home.

• Future-proof – Matter is continuously evolving and already supports use cases such as vehicle-to-grid (V2G), dynamic electricity tariffs, and CO₂-optimized consumption.

Lighting & Switches – Lamps, dimmers, push-buttons, power outlets

Security – Door locks, contact sensors, smoke & CO detectors, cameras

Shading & Coverings – Roller shutters, blinds, awnings

Climate & Indoor Comfort – Thermostats, air conditioners, air purifiers, fans

Energy Management – ​​Solar systems, battery storage, heat pumps, wallboxes, dynamic electricity tariffs

Sensors – Temperature, humidity, air quality, presence, water leak, and much more

Appliances – Refrigerator, washing machine, dishwasher, oven, robot vacuum

Media – Speakers, video players, remote controls

A Wi-Fi network – Matter communicates via your existing home network (Wi-Fi or Ethernet).

A smartphone or tablet – For setup via QR code (iOS or Android).

A compatible control hub (controller) – e.g., an Apple HomePod, Amazon Echo, Google Nest Hub, or a specialized energy management system. The controller manages your devices and enables automation. The good news: control hubs are increasingly integrated into devices you may already have at home—such as smart TVs, speakers, or Wi-Fi routers. The number of such devices is constantly growing.

For Thread devices: a Thread Border Router – This is already integrated into many current controllers.
