Wireless M-Bus Gateway V4
Description
Battery-powered gateway for regular remote reading of up to 64.000 wireless M-Bus (868 MHz) and Sensus RF consumption meters (e.g. water meters, heat cost allocators) via NB-IoT, LTE-M mobile radio or LoRaWAN to the Internet. Suitable for indoor and weather-protected outdoor installation. Ideal for intra-year consumption information (uVI) and billing in the housing industry.
Features
- wM-Bus meter data upload via NB-IoT or LTE-M mobile radio (2FF / Mini SIM card)
- Secure DTLS data transmission (client + server certificates) via mobile radio
- Connection via CoAP and DTLS (NB-IoT, LTE-M) or MQTT (LTE-M) to the Lobaro platform
- Direct connection via MQTT (LTE-M) to third-party systems possible.
- Alternative upload via LoRaWAN 1.0.2 (EU-868)
- Compatible with wireless M-BUS S1, C1/T1 modes (868 MHz) meters
- Compatible with Xylem Sensus RF Bubble Up (868 MHz)
- Compatible with Müller Funk (ME protocol, Walk-By) for µon and µflow skyW-2 and skyE-2
- Internal memory, for over 64.000 telegrams
- Whitlist for up to 2.000 individual meters
- Remote configuration
- Signed firmware updates (FOTA) via mobile radio

Regarding all variants, please contact our sales team.
embedded SIM (eSIM)
Instead of an integrated circuit located on a removable SIM card, typically made of PVC, an eSIM consists of software installed onto an eUICC chip permanently attached to the gateway PCB. Advantages are the avoidance of corresive contacts in challenging outdoor environments.

LED signal patterns
The device has 3 three LEDs (B, G, R = Blue, Green, Red), labeled Status on the PCB: 🔵🟢🔴.
See also item item (4) of internal view.
Patterns during booting/restart
- 🔵⚪🔴 B and R on: Device is in Bootloader Mode (not actively running, remove config adapter press reset to leave Bootloader Mode).
- 🔵->🟢->🔴 Quick cycle B, G, R for ~0.5s: Device just booted, either after power on, reset b button or software, or after a hard failure.
- ⚪⚪🔴 R flashes repeatedly on and off in 1s interval: critical failure during boot (failed to start application).
Patterns during normal operation
- 🔵⚪⚪ B flashes 1s on and 1s off in loop: building LTE connection to mobile provider. Followed by:
- ⚪🟢⚪ Short G flash on success.
- ⚪⚪🔴 Short R flash after connection failed.
- ⚪🟢⚪ G flash during installation mode while collecting wireless M-Bus telegrams.
Exceptional patterns
- 🔵⚪🔴/⚪🟢🔴 Quickly changing between R & B and G & B every 5s in a loop: Modem is in connection restriction mode - keep device on power, will fix itself after 30min.
