  • Page 5: Meter Compatibility

    Meter Compatibility The LoRa Module is compatible with Sensus PolluStat and PolluTherm F meters with a compatible firmware ver- sion. If the LoRa Module is mounted in an incompatible meter, this is indicated in the OTC App. Table 2 shows the minimum firmware versions required.

  • Page 6: Mount And Start-Up The Device

    Please make sure that the module’s push button (2) is facing upwards • Please make sure that Interface connector of the meter (1) fits the Interface connector of the module (3). Figure 2: Sensus PolluStat meter (left) and LoRa module (right) 5.3.2 Network preparation For the module to connect to the LoRaWAN network, it needs to be registered in the network server.

  • Page 10: Downlink

    6.3.1 Downlink The LoRa Module supports configuration via downlink, i.e. sending commands to an end-device via the LoRaWAN network. Note that this feature should only be used sparingly due to bandwidth consideration. Communication via downlink can only be made in a short window after an uplink transmission from module to server.

  • Page 11: Adaptive Data Rate (Adr)

    Adaptive data rate (ADR) The LoRa Module uses Adaptive Data Rate (ADR), part of the LoRaWAN standard, where the network server deter- mines the optimal rate of communication for the module based on current signal conditions. In best case, the mod- ule will use its highest data rate (DR5) in order to be as energy efficient as possible.

  • Page 12: Message Formats

    Message formats The LoRa Module has several different message formats. Each one will be described in detail in this section. 6.6.1 Message structure Message formats Standard, Compact, Scheduled – Daily redundant, Scheduled Extended, Combined heat/cooling and Sensus are encoded in M-Bus format (M-Bus standard EN 13757-3:2013). Message format JSON is encoded in JSON format.

Figure 6: JSON message example 6.6.2.4 Scheduled mode For message formats of type “Scheduled” (Scheduled – Daily redundant and Scheduled – Extended), two types of messages will be transmitted from the module - a clock message and a data message. The difference between the two is described in Table 11.
