RCM-LRW10 Module for GWFCoder

The GWFcoder radio module RCM-LRW10 from GWF MessSysteme eliminates the need to change meters for the migration of water and gas meters with GWFcoder to an LPWAN network. With simple and quick on-site installation via Plug & Play, no programming is required and is ready for immediate use with a waterproof housing (protection class IP68).

Features

  • Backwards Compatible: No meter change required when migrating water and gas meters with GWFcoder interface into a Low Power Wide Area Network (LPWAN)
  • Battery Powered: LoRaWAN radio module with up to 15 years battery lifetime in custom-tailored RF Mode
  • Long Range Performance: Range up to several kilometers
  • Plug & Play Installation: Easy and fast on-site installation with auto interface-detection and activation in LoRaWAN, no programming required
  • LoRa Alliance Certified: Interoperable with different LoRaWAN network providers
  • Waterproof Design: Protection class IP68 for pit installations
  • Secure Communication: Data security via AES-128-bit end-to-end encryption over 2 independent security layers
  • Adaptive Data Rate: ADR support for higher transmission intervals with consistent battery life
  • Split Connection: Cable connection to the meter enables remote installation
  • Infrared Configuration Interface: For on-site parameter configuration

Technical Specifications

  • Frequency Band: LoRaWAN 868 MHz
  • Meter Interface: Meter with GWFcoder or GWFcoder MP register with SCR(IEC) or ECO interface
  • Compatible Meters: All water and gas meters (domestic and industrial) with GWFcoder/GWFcoder MP register
  • Transmission Interval:
  • Configuration 1: Fixed transmission interval (daily)
  • Configuration 2: Dynamic transmission interval (up to 15 minutes, depending on meter interface and LoRaWAN network quality)
  • Activation Type: OTAA or ABP
  • Data Transmission: Latest register value and additional information
  • Monitoring Features: Integrated connectivity monitoring and automatic reconnecting mechanisms

Warnings and Alerts

The module supports various configurable warnings (all enabled or disabled, available from radio module version ≥1.4.0):

  • Continuous flow / Leak (water only)
  • Backflow (requires on-site reset)
  • Pipe burst (meter size must be configured on-site)
  • No usage over a period of 30 days

Use Cases

  • Simple readout of water and gas meters with GWFcoder registers without necessity to access buildings
  • Migration of installed meters with GWFcoder registers to a smart metering system via LoRaWAN
  • Energy monitoring, energy reporting and consumption accounting
  • Integration of water and gas meters with GWFcoder registers in smart city projects

Thinger.io Integration

The RCM-LRW10 integrates with Thinger.io through LoRaWAN network servers, enabling remote monitoring and management of water and gas meter data.

Requirements

A LoRaWAN server is required to communicate the RCM-LRW10 into Thinger.io, some options are:

Alongside, the corresponding plugin for the selected LoRaWAN server needs to be installed in your Thinger.io instance.

Get Started

Installation

Look for the plugin in the Thinger.io Plugin Store and install it in your Thinger.io instance. Once the plugin is installed a new Product will be created for this device.

Configuration

The Product is already preconfigured, check that the auto provision prefix matches the one selected in your LoRaWAN server plugin in Thinger.io, or change it to your desire.

Usage

Start sending uplinks for autoprovisioning devices and buckets. This product also provides a predefined dashboard and downlinks.
