Add topic to the protocol documentation

[walterdevos]

Is it an idea to add the MQTT topic to the protocol documentation? .../cmnd/nspanel/nspsend It's never ever discussed anywhere. :-)

The protocol page only describes the serial protocol, the mqtt topic stuff is tasmota related. https://tasmota.github.io/docs/MQTT/#commands-over-mqtt

Absolutely but in this case topic depends on nextion firmware and it is not described anywhere (except digging into the code) would like for example knowing how to setup external temp, looks like something like that that is working

{"HMI_weather": 1, "HMI_outdoorTemp":{"current":11, "range": "10,12"}}
