Wireless M‑Bus → MIOTY Bridge (EMB‑200)

OMS Wireless M‑Bus to MIOTY TS‑UNB bridge with ultra‑robust LPWAN performance
5G/4G Backhaul Secure · Rugged Industry Grade
EPPELTONE EMB‑200

Key Features

  • Converts OMS W‑M‑Bus frames into MIOTY telegrams with payload mapping
  • Fragmentation/interleaving for interference resilience
  • Edge normalization (DLMS COSEM profile export optional)
  • 5G/LTE backhaul with MQTT/HTTPS to cloud HES/DCS
  • Configurable filtering, aggregation, store‑and‑forward buffering
  • Strong crypto: AES‑128/256, Secure Boot, signed OTA
