[HELP] Thingsboard Gateway correct RPC request over MQTT

[peterandthejetsons]

Hello,

I have the Thingsboard Gateway v3.1 installed in a docker environment on a Ubuntu 20.04 server. I have some devices connected to Thingsboard Gateway throught central MQTT broker. I'd like to control these devices throught MQTT with RPC requests, but I'm always get the following error message:

""2022-09-21 15:09:43" - |ERROR| - [mqtt_connector.py] - mqtt_connector - server_side_rpc_handler - 743 - RPC not handled: {'device': 'shellyplus1pm-441793955bcc', 'data': {'id': 61, 'method': 'Switch.Set', 'params': False}}"

I can control the device with simple mosquitto client with the following command:

root@mosquitto:~# mosquitto_pub -h 192.168.1.13 -p 1884 -t 'shelly1pm/shellyplus1pm-441793955bcc/rpc' -m '{"method":"Switch.Set","params":{"id":0,"o
n":"false"}}' -u user -P password

My MQTT config is the following:

I'd like to ask for your help in this issue. If you need further information, please let me know.

Thanks in advance.
