Measuring, Controlling, Managing, Automation

Our Solutions

Energy measurement

With SmartPi, e.manager nd and e.manager mc, electricity consumption and generation can be measured, recorded and made available in the network or the Internet.
In conjunction with a photovoltaic system or other renewable energy generators, the e.manager can be used to optimise your own consumption.
The SmartPi turns the RaspberryPi into a fully-fledged SmartMeter. An MQTT and Prometheus interface ensures interoperability with other systems.

The current is measured contactlessly via current terminals.

Photovoltaics

The e.manager is the all-round solution for manufacturer-independent monitoring and control of photovoltaic systems, small wind turbines and other renewable energy producers.

The integrated fault detection informs you in case of problems and faults on inverters or photovoltaic modules.

Whether dynamic 70% control or power reduction via ripple control receiver. The e.manager can implement the EEG guidelines for feed-in management for any plant size and sell them on the electricity exchange via the direct marketing interface.

Direct marketing

The e.manager's direct marketer interface enables the sale of regeneratively generated electricity from photovoltaic plants, biogas plants and wind power plants via the market premium model on the electricity exchange, among other things.


In contrast to many competitors, the integrated VPN interface for encrypted data transmission establishes a secure connection to the direct marketer.
This ensures high reliability and low costs.

Optimize own consumption

The e.manager simply optimizes your own consumption. It continuously measures and monitors your electricity generation, consumption and feed-in. You can use rules to automate complex processes.
So you can easily increase your own consumption.

Monitoring, controling and automation

With the e.manager or the SmartPi you can easily and safely monitor your energy producers and consumers.
In case of irregularities or errors you will be automatically informed by e-mail.

Using graphical interfaces, you can easily solve complex tasks and control other components with both e.manager and SmartPi (Node-Red).

With the help of expansion cards, the e.manager can be extended with a variety of interfaces.

The SmartPi can be expanded with the usual additions for the Raspberry Pi.

Energy rethought

e.manager

Enter the world of energy automation

 
As the central control unit, the e.manager controls, regulates and
monitors all energy components in your residential or commercial building.
Integrated into the distribution system, it intelligently networks energy
producers and consumers, thus optimising your energy costs.
 
Equipped with numerous interfaces, various inverters, energy meters
and sensors, such as temperature sensors and switches/contacts, can be
connected to the e.manager. Consumers, actuators (shutters, pumps, etc.),
boilers, heat pumps or heating cartridges can be controlled
via WLAN sockets, relays, digital or analog outputs.

Automated rules ensure reliable, optimal and smooth control of your components without burdening you with technology in everyday life.

Photovoltaic system monitoring

Via the web portal you can easily monitor, control and evaluate your system from anywhere in the world.

Optimization of internal consumption

With the e.manager you can
control consumers and battery storage to optimize your own consumption and thus
save energy costs.

Direct marketing

With the e.manager, direct marketing of photovoltaic plants, biogas plants and wind power plants can be easily carried out. For this purpose, the e.manager has a so-called direct marketing interface.

Feed-in management

The e.manager can implement the
feed-in management guideline suitable for any system size.

Data privacy

Your data is stored anonymously in the cloud. If you still want to know your valuable data at home and not in the cloud, you can also use e.manager without the Internet.

Integrated error detection

The integrated fault detection informs you in case of problems and faults on inverters or photovoltaic modules.

Turn your Raspberry Pi into a smart meter

SmartPi 3.0

SmartPi, your personal smart meter

 
The SmartPi expansion module extends the Raspberry Pi by
interfaces for voltage measurement and non-contact current
measurement and thusbecomes a fully-fledged SmartMeter that
controls and records powerconsumption and power generation
and makes it available in the network or the Internet.
 
With SmartPi, power consumption data can be
conveniently recorded, evaluated and used as
a basis for energy saving measures.
 
With SmartPi you reduce energy costs
in your company and at home.

Evaluate

All measurement data (e.g. voltages, currents, powers, frequencies, Cos Phi)
are recorded and stored on the integrated SD card. Via the integrated web server,
the measured values can be conveniently called up and evaluated by
the smartphone or computer.

Connecting

The integrated REST, MQTT interfaces enable easy data exchange with other devices.
An interface to the Prometheus
database is also available.

Compatible with Raspberry Pi© and ESP32

The SmartPi is compatible with all Raspberry Pis© models 2 V1.2 and higher and there are implementations for the versatile ESP32 and ESP2866 modules from Expressif©.
