Hi, I have a question regarding MQTT host server discovery from a Tasmota SONOFF device.
Compiled the code with USE\_DISCOVERY and MQTT\_HOST\_DISCOVERY enabled in the source code.
Using the mosquitto MQTT broker.
The device is not able to discover the MQTT server, but if I use the console command MqttHost to set the IP of the MQTT server it works.
Any advice in this regard?

This looks like a question for the Home Assistant forums.

Or the tasmota forum, it appears to nothing to do with node red at all.
