CHP Monitor and the Stromfee Diary: What You Absolutely Need to Know


Combined Heat and Power plants (CHP) are increasingly being discussed when it comes to efficient energy generation. In conjunction with intelligent monitoring systems like the Stromfee Diary, new possibilities open up. But what data can the Stromfee Diary actually collect from a CHP? We answer this question for you in the following blog post.

MQTT Protocol: The Communicator

The Stromfee Diary uses the MQTT protocol (Message Queue Telemetry Transport) for data transmission. This protocol is known for its reliability and low bandwidth requirements. It ensures that all collected data is securely and in real-time transmitted to the evaluation software.

Voltage Quality

The Stromfee Diary is capable of monitoring voltage quality. This allows potential problems in the network to be detected early on.

Frequency and Phase Angle

The grid frequency and phase angle are also determined. These measurement data are particularly important for industrial applications where precise timing is crucial.

Active and Reactive Power

In addition to the already mentioned power and energy measurements, the Stromfee Diary also records active and reactive power. These data help to further optimize the energy system.

Energy Generation and Consumption

First and foremost, the Stromfee Diary measures the generated electrical energy and current consumption. It records the power in kilowatts (kW) and the energy in kilowatt-hours (kWh). This allows you to see at any time how efficiently your CHP is operating.

Temperature Measurement

In addition to energy parameters, the system also records temperatures. Whether in the heating circuit or directly on the generator, constant temperature monitoring gives you security and enables finer control of the CHP.

Operating Hours and States

Important information about the operating hours and the states of the CHP are also documented. You can immediately see when maintenance is due or if there are any malfunctions.

Gas Consumption

For CHPs that run on gas, the Stromfee Diary offers the possibility to measure gas consumption in cubic meters (m³). This keeps you always aware of the operating costs.

Additional Measurement Data

With the use of additional sensors, even data such as CO2 emissions or oil pressure can be recorded. These measurements help in further optimizing the system.

Stromfee Diary: Added Value in View

While the Stromfee Diary does excellent work in data collection, the question arises as to how these data can be used for optimizing energy supply. This is where energy management systems come into play.

Efficiency Analysis

An energy management system evaluates the collected data and provides specific recommendations for energy-efficient measures. For example, you get tips for reducing electricity consumption or for better utilization of energy generation.

Cost Savings

By optimizing the energy flow in your building or operation, significant costs can be saved. A professional energy management system helps achieve this goal.


In addition to cost savings, you also contribute to environmental protection. By using resources more efficiently, you reduce CO2 emissions and promote sustainability.

Automated Control

Energy management systems offer the possibility to automatically control energy systems. In conjunction with the Stromfee Diary, a dynamic duo for intelligent energy management is created.


The Stromfee Diary offers a wide range of data collection possibilities. In combination with an energy management system, it unfolds its full potential and leads to significant improvements in efficiency, cost savings, and sustainability.

The Stromfee Diary provides comprehensive monitoring of your CHP. From energy generation to temperatures and operating hours, you have all the important data at a glance. With the application of the MQTT protocol, fast and secure data transmission is also guaranteed.
