LoRa Gateway Software

Preface​

LoRa stands for Long Range and is a radio technology with a long range and low data throughput. This communication medium is particularly well suited to the wireless transmission of meter readings in plumbing and heating technology.

Compared to Wireless M-Bus, which was originally developed for transmitting meter data, LoRa stands out with its significantly greater range.

Fewer gateways are needed per building to obtain all meter values from the individual apartments.

General information on the compatibility of energy meters and sensors​

With the smart-me LoRa Gateway solution, it is important that the sensors and energy meters are included in the compatibility list. If they are not listed, they are currently not compatible.

Get in touch with us – your meter or sensor can be integrated at short notice. Send an email to support@smart-me.com with the subject "Neues LoRa Gerät" (New LoRa device)

In general, the smart-me Gateway solution supports the following types of energy meters and sensors:

Energy meters:

  • Heat meters

  • Cooling meters

  • Heat/cooling meters

  • Domestic hot water and cold water meters

  • Gas meters

Sensors:

  • Temperature (display, temporarily not stored)

Compatibility limitations​

For technical reasons, electricity meters are not supported with LoRa. Due to the way LoRa works, the transmission rate and data reliability are not high enough for load profile billing as used in smart-me Billing.

For this reason, LoRa is used exclusively to record meter data for which sufficient reliability and functionality can be guaranteed.

Tested LoRaWAN gateways​

  • Dragino LPS8N

  • Sensecap M2

  • Kerlink Wirnet iFemtoCell-Evolution 868

  • WisGate Edge Lite 2

  • Milesight UG56

Note: Untested devices can be integrated independently. Compatible devices only need the "Semtech" and "Data Packet Forwarder" options.

Compatibility list for meters and sensors​

Is your meter or sensor not listed?

Get in touch with us – your meter or sensor can be integrated at short notice. Send an email to support@smart-me.com with the subject "Neues LoRa Gerät" (New LoRa device).

Requirements for an integration:

  • Device EUI

  • Application key for the device (The key has 32 characters. It is supplied with the product; if not, it can be obtained from the current / previous billing provider.)

Working with LoRa field testers​

Field testers can be commissioned as any device type using their EUID and APP key.

For example, field testers can be connected as manufacturer "GWF" and type "All". This allows the tester to communicate with the gateway. The gateway does not create a metering point for the tester in the smart-me portal.

Tested with: - Adeunis ARF8123AA 868 MHz

Data quality and outage coverage​

LoRa technology is based on capturing and sending data. LoRaWAN gateways have no data storage and therefore cannot reconstruct incomplete data sets, as is otherwise the case with smart-me products.

For this reason, LoRa is not equally suitable for all types of energy.

For heat / water and gas, a brief outage or a data gap is generally not a major obstacle and can be billed without problems if it is resolved in the medium term. For electricity and its tariffing in 15-minute intervals, a medium-term resolution is not easy to achieve. In our view, LoRa is therefore not suitable for transmitting electricity data and billing it.

That is why smart-me has developed its own hardware to ensure the necessary data reliability and completeness for electricity.
