Python scripting with calculation and send data using MQTT

[devam.shah]

Hi all,

I have router RUT200 and I want to do data manipulation using python scripting, and send it on cloud using MQTT protocol.
Actual structure is Siemens make plc will give data to RUT200 over TCP connection and that data will be manipulate in teltonika router using python, and concluded data I will send on cloud.
Provide sample script if any…

How’s it’s possible?
Give me solution for same.

Thanks in advance.

Hello,

Python3 is available on Teltonika Networks devices that have enough memory for it. RUT200 does not have much memory, so Python is likely not an option for this device.

However, you should be able to achieve your goals via shell scripting.

You can create a shell script where you can use UBUS modbus calls to send Modbus requests to your Modbus servers. Then, you can proccess the response the way you need, and publish it to your MQTT broker via Mosquitto.

There’s quite a few posts on this forum that contain useful information for your case. For example, the following posts might be helpful:

RUT241 - how to check if a client is connected on wifi?

Hello, I need some help. I have a RUT241 running on a remote place. The RUT241 connects to the Internet via 4G with a private APN. I have 4 “Smart WIfI relays” connected to the RUT241. All I want to do is to check if these “Smart WIfI relays” are connected to the RUT241, and if possible create some type of alarm in case any connection is lost (via MQTT, POST, GET, whatever would do). Does anyone have any idea how to do this?
