Energy Monitoring for Buildings
Energy monitoring is often implemented with vertical integrated solutions of a single manufacturer. This approach is at a first sight simple, but it can bring to higher costs and to a sub-optimal solution to the given requirements.
Put it simply, an energy monitoring system is composed of (i) meters/sensors, (ii) a controller/data-logger and (iii) a cloud service if needed. The design of the three components are decoupled as long as they are based on standard interfaces and on open specifications. Closed specifications bring to a vertical solution, which is difficult to adapt to the particular requirements of each case.
Qeed brings a significant advantage in the deployment of energy monitoring in terms of
- functionality (e.g. energy meters with harmonic analysis);
- modularity (energy meters directly accessible with ModBus - no proprietary coupler is needed);
- form factor (e.g. three-phase energy meters in 17,5mm, current transformer with integrated voltage meters and ModBus);
- compatibility (interfaceablewith any controller, the registers list is fully released).
In the examples below, we assume that Qeed energy meters are connected to the Higeco Datalogger. This is a ModBus-capable central unit that collects the measurements and presents a user-friendly graphical interface. In addition, the Higeco Datalogger can store the data in a cloud service for secured remote access.
All components are for DIN-rail mounting, see picture below.
The datalogger can be connected to a local Ethernet network or to a GSM modem (like in figure).
The datalogger can be accessed over a local network or remotely per encrypted connection (VPN).
The data can be visualized by accessing directly the datalogger or optionally by a cloud service. The cloud service allows a reliable 24/7 access to the data and allows multi-site management.
Reports can be sent per email, alarms per SMS.

Our activity and further information
We provide a thoroughly sales and technical support to installers and system integrators for Qeed power meters and Higeco dataloggers. We developed a software to shows the ModBus registers conveniently in tables and graphs. This reduces the time-to-learn and speeds up the business of our clients.
