I am using the MQTT client and noticed that publishing a MQTT messages from a flow card, always publishes in Uppercase, therefore the command is not recognized (by Tasmota for example), is this behaviour by default, can it be changed?

The result:

```auto
$ mqtt_sub -vh 192.168.23.2 'test/#'
test/my-test-topic hello world

No My bad. Was looking in Tasmota console, there it’s uppercase, so must be logging or something. A parameter was not correct, hence it didn’t work.
