Question

Using an RUTX11, I am trying to automatically publish the GPS data over MQTT using the build in MQTT broker.

I have tried configuring modbus slave and mqtt gateway so can publish a "request" and receive back the modbus data on the subsequent "response" message. But I would rather have it publish this data regularly every 5 seconds - autonomously.

Now I am trying to use the "Data to Server" feature to publish this modbus data to the mqtt broker every 5 seconds.

However this does not seem to work. Here is my Data To Server configuration...

I just finally got this working. I had to also add a MODBUS master configuration.

Hello,

i need a while to under stand it.

And i want to create a small tutorial for this topic:

HOW TO SEND/PUBLISH GPS AND SYSTEM VALUES OVER MQTT

Switch to ADVANCED Mode.

---

Enable GPS:

---

Activate MODBUS with a MODBUS TCP SLAVE:

---

Create a MODBUS MASTER:

Add all needed System values here. REMEMBER the FIRST REGISTER ids.

Find more details about the System Values here:

https://wiki.teltonika-networks.com/view/Monitoring_via_Modbus

---

Enabble MQTT Broker:

---

Send MODBUS data to MQTT Broker with the DATA TO SERVER service

DATA TO SERVER -> ADD

Now you can connect to the MQTT Broker to the GPS topic.

The router publish all you data the the REGISTER ID and the VALUE to this topic.

Have fun.
