Question

Hi, I am using TRB145 with firmware version TRB1_R_00.02.06.1. I am testing HTTPs connection to send Modbus data in the form of JSON to https://myjson.live/my-topic-name but have not received anything. What may be the problem?

Hello,

Could you share your configuration details right here (blur out sensitive information such as IP)? Also, would you mind testing with 7.0 firmware version?

Regards.

Hi, I tested with the latest version it is working.

Is there any way to differentiate the JSON payload if the sensor has multiple instances? The present payload for a single instance is like {"data": [293, 661]} with the first one being temperature and the other one being humidity. For individual instances, it will be {"data": 293} and {"data": 661} is there any way to differentiate them like {"data1": 293} and {"data2": 661} or in single instance {"data1": 293, "data2": 661}?

Hi,

Please refer to JSON format settings: https://wiki.teltonika-networks.com/view/TRB145_Data_to_Server#Advanced_Sender_Settings

Unfortunately, it is not possible to separate data or insert phrases/words between it.

Regards.

Hi, I observed although the payload is of JSON format date (%d) is displayed as {"date": 24/09/2021 16:34:11} which is not a valid JSON it should be {"date": "24/09/2021 16:34:11"}. And if we use Slave IP (%p) and used Modbus serial the payload is like {"slaveIP": } which is also not a valid JSON it should be something like {"slaveIP": ""}.

Why is that so?

We need to put "" explicitly to make it work like {"date": "%d", "slaveIP": "%p"}.
