Energy controlling

Energy - an expensive "pleasure

Since this spring at the latest, the topic of energy has been present, often too present when it comes to costs. Politicians have also reacted, among other things with the Energy Saving Ordinance that came into force on 01.09. this year.

For example, the maximum temperature limit in workplaces in public properties is set at 19°C (with the exception of social facilities, clinics and care facilities). Common areas in which people do not regularly spend time remain unheated.

Relevant for companies: The minimum temperature of workplaces will be reduced to 19° C. In the residential sector, private households must be sufficiently informed by operators about current consumption and expected costs to be able to take savings measures independently.

Heating control via LoRaWAN

The biggest driver of energy costs continues to be heating. The importance of intelligent individual room control cannot be emphasized strongly enough. Intelligent radiator thermostats such as Vicki from MClimate are ideal for this purpose. This can be integrated into a LoRaWAN network and thus evaluated and controlled within the framework of central applications, enabling savings of up to 30% in heating energy and thus costs. Of course, the set temperature can be controlled via the built-in temperature sensor, but above all, intelligent, networked functions can be implemented, such as controlling the heating depending on the room occupancy or lowering the temperature when a window is opened. Whether the temperature can still be changed locally at the thermostat or only centrally controlled via stored logics is completely up to you. The following video shows how easy Vicki is to install:

Create added value

Although the Vicky has already integrated a comprehensive logic for heating control, it becomes really exciting in the context of a more comprehensive control system that includes additional sensors and is based in the background on a simple but powerful visualization and logic platform. We would be happy to advise you on this.

Further sensors in connection with the heating control

AM307 Room sensor
Room climate sensorA multifunctional sensor for monitoring indoor climate with div. parameters such as temperature, humidity, light, CO2 concentration, HCHO/O3 content, TVOC, air pressure, PM2.5, PM10 and motion.
WS301 Window contact
Window Magnetic ContactA simple magnetic contact that detects door or window openings and provides the data via LoRaWAN.
VS121 Workplace Sensor
Occupancy sensorAs a workstation sensor, it is used to monitor occupancy and control utilization in modern workspaces. It supports up to 12 mapped regions for detection with a detection rate of up to 95%.

LoRaWAN Gateways and Integration into Building Management

Of course, a LoRaWAN network requires a LoRaWAN gateway and a LoRaWAN network server. Especially in the building sector, however, we would like to present two special solutions here, namely gateways that already have the LoRaWAN Network Server integrated. In our eyes, this is a practical solution for local installations, especially if the data is to be made available to a local Building Management System (BMS).

Helium gateway ug65 from Milesight

On the one hand, the Milesight UG65 offers an integrated LoRaWAN network server and even an integrated Node Red. This makes it very easy to implement very individual integrations and connect a wide variety of systems. Of course, the classic packet forwarders can also be used to work with a LoRaWAN network server such as Actility, Loriot or melita.io.

Wattsense Box

On the other hand, the Wattsense Box. In addition to an integrated LoRaWAN Network Server, it offers "out-of-the-box" extensive integration into various building management systems. The integrated protocol converter unifies more than 10 field communication protocols, including Modbus TCP/IP, Modbus RTU, BACnet IP, BACnet IP Server, M-Bus, wM-Bus, LON FT10, LON IP-852, LPB - Local Process Bus, Diematic and KNX.
