Teltonika MQTT and Modbus

TG in this academy is Teltonika Networks. TRB/RUT publish numeric MQTT or MQTT-Modbus.

Teltonika Networks (TG)

Lithuania industrial cellular routers and gateways. Best when the plant already has PLCs, energy meters, or RS485 instruments.

Families

  • TRB1 / TRB2 / TRB500 — compact IoT gateways (TRB246: Ethernet, RS232, RS485, dual SIM, Modbus/DNP3/DLMS)
  • RUT2 / RUT9 / RUTX / RUTM — industrial routers, MQTT, VPN, RMS
  • RMS — Teltonika remote management (optional; not Factora)

Industrial protocols on RutOS include Modbus RTU/TCP, MQTT publisher/subscriber, and on some images MQTT Modbus Gateway.

Path A — native MQTT publisher

Collect registers locally, publish:

{"value": 38.2, "messageId": "trb-1710000000"}

to factora/{slug}/devices/{code}/telemetry with device code/token.

Path B — MQTT Modbus Gateway (TRB246)

The gateway subscribes to a request topic and publishes responses. That is not Factora’s ingest shape. Put an adapter (Node-RED on the router, or a small mapper) that:

  1. Polls Modbus (or uses Data to Server)
  2. Writes Factora ingest MQTT/HTTP with a single number

Do not point Factora MQTT connector at Teltonika request/response topics and expect OEE to move.

Path C — meters and VFDs

Map register → Factora type (kW, A, rpm). Scale and offset on the Teltonika so Factora stores engineering units.

1. Teltonika MQTT Modbus Gateway request/response topics are the same as Factora ingest topics.
2. TRB246 RS485 is a reason to pick Teltonika over Blueiot tags.
