Function description
The Long Range Wide Area Network (LoRaWAN) is a low-power network protocol. The Lo-
Ra alliance establishes the LoRaWAN specification; it is freely available and uses a special
modulation technology.
The LoRaWAN module sends the meter data over a LoRaWAN wireless network to an appli-
cation server (control unit) that the end customer can access. The meter data is transmitted
immediately after start. The mobile ‘Elvaco OTC APP’ from Elvaco can configure the module.
Message type ‘Standard’ for the LoRa telegram includes the following data points:
● Energy
● Volume
● Power
● Flow rate
● Flow temperature
● Return temperature
● Serial number
● Error flag
At a transmission interval of 60 minutes, a battery life of 11 years can be achieved; at a
transmission interval of 160 minutes, up to 16 years at good transmission quality.
