[HELP] Can we use MQTT as transport in Modbus Connector?

[psxbox]

Describe the issue
More than 1000 of our Modbus RTU devices are connected to MQTT broker via RS485-MQTT gateway. This gateway subscribes to the MQTT {clientId}/down topic and sends data from this topic to the RS485 port. And the data from RS485 is sent to {clientId}/up typical. The data is transmitted through the MQTT broker without any modification (in binary form). So can we use MQTT as transport in Modbus Connector?
Thanks!

Hi @psxbox,

Thank you for your interest in ThingsBoard IoT Gateway.

Unfortunately, I don’t see way on how to do this easy, I see the only one option is to use MQTT connector, to get data and process it using bytes converter, but it will be really inconvenient to configure this, because the is no ability to convert uplink data to Modbus entities, using default functionality.

Really working way is to create custom uplink converter for MQTT connector and use it to convert incoming bytes to Modbus entities and collect data from them.
