M-bus wireless devices

М-bus (Meter-bus) is a new European standard for remote reading of tax instruments and different types of sensors. The reading is accomplished by several different methods - from direct reading of current indication of the instruments to fully remote reading of all devices in the net by GPRS technology. The use of M-bus interface allows fully electronic reading of data with all the benefits of it.

In addition, wireless m-bus was shortly introduced to ease the readings in already existing buildings. Wireless readout simplifies the installation, eliminates cables (which reduces cost) and allows walk-by readouts. It works in permissable 868 MHz range in Europe and can be in several different modes, according to wireless m-bus standard.

We produce wireless m-bus concentrators and repeaters, which can work in modes T, S and C, allowing data collection from up to 450 meters. We support AES-128 Mode 5 encryption as it is defined by the standard. Our main concentrator have also wired m-bus slave interface, which is ideal for mixed-type networks with one centralised reading device. We also produce wireless concentrator, powered by m-bus, which is quite flexible in mixed-type networks.

In the future wireless devices will become more and more sophisticated, so we will continue to expand our product line in wireless devices.

Description

First member of our wireless line is the stationary wireless concentrator WRM-TS. It is intended to acquire data mostly from meters, working in wireless m-bus T, S or C modes. Up to 480 devices can be binded to our concentrator. It has also wired m-bus interface, which allows reading of all saved data through wired m-bus. WRM-TS is fully programmable and commands are ASCII-based, which allows easy installation even with simple serial terminal. Power supply is external (adapter, included in package), if ordered can be produced for DIN-rail mounting.

On the other hand, WMR-IoT is intended for quick walk-by remoter reading of wireless meters. It works by default in modes T+C, but of course can be set in S too. Powered directly through USB port of a notebook/tablet/PC. We have two version - v2 is for direct plug through OTG adapter and is more suitable for laptop use. v3 is designed with belt clip and USB C connection plug, we provide 0.5m USB C cable with rach device. To read wireless meters with WMR-IoT v2 and v3 we provide free Gineers software, which also can be used for determine signal strengths in desired building or just analyzing the current network.

For range extensions we produce different types of wireless m-bus repeaters. That includes repeaters on mains power supply 230Vac, 9-30Vdc/Vac and battery powered. We also have options for indoor and outdoor enclosures. Our repeaters usually work in T+C mode, do not limit hops and are more like plug-and-play devices.

Mixed type concentrators and different wireless sensors are extending our portfolio in that area. We produce pulse-to-wireless m-bus converters, temperature and humidity sensors on battery with wireless m-bus, converters from wireless m-bus to RS-232, converters from wireless m-bus to wired m-bus (powered from wired m-bus), wireless m-bus with GPRS and WiFi options. This gives opportunity to create rich ecosystem with wireless m-bus and to have different options to embedd wireless devices in full BMS/SCADA systems.

We also do have our own wireless WEB portal, on which we show consumption for whole buildings. To do that we install stationary wireless m-bus concentrators and through Ethernet or GPRS we dp read remotely all the data. Then it is populated on our own platform and can be used by landlords or single clients. More about this in section Software.
