Look like there’s still a lot to learn about your commenting setup

print(pres) // my mod as well, including the next line

print(gas)

client.publish(topic_pub_temp, temp)
client.publish(topic_pub_hum, hum)
last_message = time.time() time.sleep(30)


except OSError as e:
restart_and_reconnect()

“If your MQTT broker requires username and password, you should use the following line to pass your broker username and password as arguments.

client = MQTTClient(client_id, mqtt_server, user=your_username, password=your_password)”

Not that simple, have used follow code:

client = MQTTClient(client_id, mqtt_server, user=b’your_username’, password=b’your_password’)
