DeprecationWarning: Callback API version 1 is deprecated

I get the following error:

(foobar) pi@meteotux:~/rpi-mqtt-monitor $ python3 /home/pi/rpi-mqtt-monitor/src/rpi-cpu2mqtt.py -d

  client = paho.Client(client_id="rpi-mqtt-monitor-" + hostname + str(int(time.time())))
MQTT error:  failed to receive on socket: [Errno 104] Connection reset by peer

Any help to this?

And also this makes no sense: Update Available: {"installed_ver": "0.8.9", "new_ver": "0.8.9"}

Hi, I think that the DeprecationWarning is not related to the connection error. Are you sure you have entered the correct host name and port?

[WirthmU]

This is the setting: in config.py

# MQTT server configuration
mqtt_host = "192.168.1.158"
mqtt_user = "admin"
mqtt_password = "XXX"
mqtt_port = "1883"
mqtt_topic_prefix = "indiMQTT"

It is the same setting that another MQTT client is using that is working:

Is your script using TLS/SSL? and can certificate validation be disabled?

[hjelev]

No it doesn't use TLS/SSL. How did you installed the script? What is your paho-mqtt version, is it 1.6.1 ? I remember I have pinned version 1.6.1 as others were causing issues.

What is your paho-mqtt version, is it 1.6.1 ? I remember I have pinned version 1.6.1 as others were causing issues.

Hi, thank you, this allowed me to correct errors with paho-mqtt.

pip install paho-mqtt==1.6.1
