- The battery or mains powered wireless M-Bus gateway B4 is highly configurable plug-and-play device used for collecting data from Wireless M-Bus meters / sensors and transmitting the data using LTE CAT-M1 and MQTT protocol
- Long range and high sensitivity internal (or external mounted) antennas
- To maximize the battery lifetime possible configuration to listen number of minutes, specific time during day, specific days and limit number of packets stored per meter / week / day / hour
- The gateway firmware can be upgraded remotely using MQTT
- B4 series gateway can be used with Lansen R4 series repeaters and transmit additional information (see datasheet)
- Configuration can be done with: Lansen Wireless M-BUS programming dongle together with our program, Lansen Configurator, other wireless M-BUS transmitters or remotely using the MQTT protocol
- Possible to activate 128 bit AES-key encryption
- Gateway suited for harsh environments, operating temperature: -30…+85 °C, protection class: IP40, IP65 and IP67
- IoT LTE M SIM card needed (acquired separately)
