Mqtt user e password

[wifi75]

Hello How I can set user end password line in configuration file?

In the script file, before client.connect, specify your user and password:
client.username_pw_set("user", "password")

In the script file, before client.connect, specify your user and password: client.username_pw_set("user", "password")

Hello I looked at ospiLCD-mqtt.py file but there is no client.connect entry

Look at the script here on GitHub: line 257

Look at the script here on GitHub: line 257

like this ?

=== Setup MQTT client, actions ===

client = mqtt.Client()
client.on_connect = mqtt_connect
client.on_message = mqtt_message
client.connect(mqttAddress, mqttPort, 60)
client.username_pw_set("user", "password")
client.loop_forever()

and then ??

Set MQTT info (defaults to localhost, if MQTT server is running on Pi)

mqttAddress = "127.0.0.1"
mqttPort = "1883"
user = "myuser"
password = "password"

As I wrote initially, I believe the user and password need to be specified BEFORE the client.connect function is called.

ok like this:

# === Setup MQTT client, actions ===
client = mqtt.Client()  
client.on_connect = mqtt_connect  
client.on_message = mqtt_message  
client.username_pw_set("user", "password")
client.connect(mqttAddress, mqttPort, 60)
client.loop_forever()

but also this is ocrrect?

mqttAddress = "127.0.0.1"
mqttPort = "1883"
user = "myuser"
password = "password"

I tried like this but after running the scrip it gives me an error:
