Overview

The maintenance-free Lobaro Solar Wireless M-Bus Gateway collects consumption data from up to 500 commercially available water meters, heat meters, heat cost allocators, etc. with 868 MHz wireless M-Bus radio interface or Sensus RF Bubble Up and forwards them regularly encrypted via NB-IoT or LTE-M1 mobile radio or LoRaWAN to the Internet for daily or frequent evaluation.

Thanks to the 100% battery-free design and the permanent power supply by the integrated high-performance solar cell, meter data can be transmitted several times a day in many applications when mounted with daylight incidence. The achievable readout intervals can, with a suitable installation location, be many times higher than with our battery-powered variant and there are no costs for battery changes. In addition to the application for billing purposes, this innovative design also enables novel areas of application in the field of predictive maintenance.

Quick Start

Differences to battery powered variant

This device differs from the battery powered variant in the following ways:

• The device can't be opened in any way - It was sealed with glue during production to achieve high waterproofing for outdoor use.
• A LTE-M / NB-IoT SIM card has been already inserted by Lobaro. Please contact Lobaro if your own sim cards should be inserted during production before sealing.
• The only kind of configuration adjustment can be done via the Lobaro platform or LoRaWAN downlinks. The USB cable option is not available.
• The device is shipped in standby mode. Before first use, it must be activated via the magnetic contact on the housing indicated by a dot.
• The device uses an audio buzzer instead of an LED for feedback on power level and operating status.
• The default WAN selection is "LTE". Please use the Lobaro Platform to switch to LoRaWAN if this is the needed uplink technology. 

Initial Startup

1. Shortly (< 1 second) hold an magnet to the dot marking on the housing
   1. Release the magnet 
   2. The devices indicated the current power level by audio (3-0 range, 3=fully charged)
   3. If the device is in "standby" mode a descending tone is played after the energy level audio indication
   4. If the level is not 3 or at least 2 place the device in a position with daylight incidence for some hours and check again later (1)
2. To reset the device hold the magnet for 5 seconds+ to the dot marking until three fast beeps
   1. A rhythmic tone sounds until three fast beeps
   2. Release the magnet
   3. An ascending tone signals the restart / reset of the device
   4. If the device was in standby mode, this flag was reset by the activation.
3. Login into your Lobaro Platform account
   1. The device will upload it's status after an initial wMBUS collection phase
4. The device is ready for use in the configured operating mode

Magnetic Contact

The Solar Wireless M-Bus Gateway has a magnetic button that can be activated via the side of the housing marked with a dot. This can be used to query the current energy level of the internal capacitor and to initiate a reset with subsequent wireless-MBus readout.
