Smart Energy Consumption Monitoring
Keep an eye on your energy use—smart, automatic, and efficient.
Why Is It Important to Measure Energy Consumption?
If you want to save energy, you need to know where, when, and how much you’re using. How much power is currently being drawn from the grid? How much energy is your solar system generating? What is the battery’s charge level? Which devices are drawing how much power? With LOXONE, you can see at a glance where energy is being wasted and how you can use it more efficiently.
How Can I Measure Energy Consumption?
Energy takes many different forms in a building. Examples include electricity, heating, cooling, gas, and much more. With LOXONE, all forms of energy consumption can be tracked. Below, we’ll focus on electrical energy—electricity consumption.
Direct Measurement
Indirect Measurement Using a Current Transformer
Reading Measurement Values via Interfaces
Which one is the right choice depends on your specific situation.
On the one hand, it comes down to the conditions on site: What does the wiring look like? What exactly needs to be measured?
On the other hand, there are standards, guidelines, and regulations to consider: How precise do the measurements need to be? What certifications are required?
One example is MID certification. This is an EU-wide standardized legal framework for billing based on measuring instruments.
Direct Measurement
When current flows through the measuring device itself, this is called direct measurement. This refers to meters that are connected directly to the circuit or the device. No additional sensors or current transformers are required.
Energy Meter 1-Phase Tree
The MID-certified Energy Meter 1-Phase Tree makes it easy to monitor the energy consumption of devices or groups of devices connected to a single circuit.
Application: Often used in homes or small offices to measure consumption in individual areas.
Energy Meter 3-Phase Tree
The Energy Meter 3-Phase Tree is MID-certified and measures power consumption across all three phases. This is especially necessary in larger installations or commercial applications.
Application: Ideal for buildings or devices that require three-phase power—for example, offices, service entrances, or large loads such as EV chargers.
Smart Socket Air
This smart outlet not only measures power consumption but also lets you control devices intelligently.
Application: The Smart Socket Air eliminates standby power: it detects standby consumption and switches off when devices aren’t in use.
Power Supply & Backup
The Power Supply & Backup ensures a reliable power supply and smooth operation during power outages. It also monitors the power consumption of its 7 outputs.
Applications: Single-family homes, offices, and a wide range of other applications that need a reliable power supply and consumption monitoring.

Indirect Measurement Using Current Transformers
With current transformers and compatible meters, the current in an electrical conductor can be measured without interrupting the circuit. They’re often used to measure higher currents or when direct measurement on the circuit isn’t possible or practical.
Energy Meter for 1&5A Current Transformers Tree
The MID-certified Energy Meter for 1&5A Current Transformers Tree works with current transformers that provide a 1A or 5A output signal. This type of transformer is required in larger installations with higher currents, such as industrial settings, large machinery, or power distribution systems.
Perfect for this:
- 5A Current Transformers 200A 24mm (3 pcs.)
- 5A Current Transformers 400A 35mm (3 pcs.)
Application: Suitable for large commercial or industrial applications, such as manufacturing plants or large commercial facilities that use high currents.

Reading Measurement Data via Interfaces
“Reading” refers to collecting and transmitting data from various measuring devices or meters. The Miniserver features numerous interfaces for analyzing energy flows and data from a wide variety of sources.
M-Bus Extension
The M-Bus Extension lets you integrate devices that communicate via the M-Bus protocol (e.g., older electricity meters) into LOXONE. It also lets you read data from other meters, such as gas, water, or heat meters.
IR Meter Reader Air
The IR Meter Reader Air reads compatible electronic household meters (eHZ) directly via their infrared interface. It can also read heat meters.
Modbus Extension, Air & Tree
These products let you integrate devices with a Modbus RTU interface. Modbus RTU meters are used to measure electricity, water, gas, heating, or cooling.
P1 Meter Reader Air
The P1 Meter Reader Air is used to read DSMR P1 meters. These smart meters are mainly found in new buildings. Depending on the meter, they can also measure gas, water, or heat, for example.
Modbus TCP
The Miniserver features a built-in Modbus TCP interface—no additional accessories needed. This lets you integrate devices such as inverters, energy meters, or heat pumps into your energy management system.
LOXONE Library
The LOXONE Library is a collection of templates and guides for integrating devices into LOXONE via a wide variety of interfaces.
