Have you made any changes to how SkyWeather2.py connects to the MQTT broker?
Thanks,
Jason

Hi Jason
No I havent made any changes in SkyWeather2.py. Below is the mqtt secyion of this file:
import paho.mqtt.client as mqtt
# set up MQTT
if (config.MQTT_Enable):
state.mqtt_client = mqtt.Client(client_id="SkyWeather2")
state.mqtt_client.connect(config.MQTT_Server_URL, port=config.MQTT_Port_Number)
import publishMQTT

Okay cool! Within publishMQTT.py, please add a properly indented print statement within the publish function. Manually run the SkyWeather2.py script for 25 minutes. While the script is running monitor the output and broker using mosquitto_pub when the print statement gets printed to the output. If possible, please capture the script output before and after the print statement appears in the output. If possible, do the same for mosquitto_pub.
Thanks,
Jason

hi Jason
sorry but confused regarding adding print statement to publishMQTT, could you give me an example?
I installed mosquitto client on the Skyweather pi and ran the following which was received OK on my remote mqtt broker.
sudo mosquitto_pub -h 192.168.1.16 -u user -P passws -t "skyweather2/state" -m "Hello world"
2022-05-06 17:53:37 DEBUG (MainThread) [homeassistant.components.mqtt] Received message on skyweather2/state: b'Hello world'

Hi Jason here is the full publishMQTT.py import config import state import paho.mqtt.client import paho.mqtt.publish as publishMQTT def publish(): if (config.SWDEBUG): print("--->Sending MQTT Packet<---") #state.mqtt_client.publish("skyweather2/state", state.StateJSON) publishMQTT.single("skyweather2/state", state.StateJSON, hostname="192.168.1.16", auth={username:"username", password:"password"}) Looks like you already have a print statement present in the publishMQTT.publish function. I'm looking for the output in the SkyWeather2.py and mosquito_pub that occurs when you see "--->Sending MQTT Packet<---" appear in the output of the SkyWeather2.py script. Thanks, Jason |

Hi Jason
I never see "--->Sending MQTT Packet<---" in the skyweather2py output.
However I do see this error repeated many times:

I also see this error in the skyweather.py output (masked out username and password)

username and password have to be enclosed in quotes. The error above is syntactical. You’ll need to fix that in publishMQTT.py before it will run the code within the script.
Thanks,
Jason

I have tried every combination to get the username and password in quotes but I still see conection refused not authorized message.
When the new version of software is released is there any support for MQTT username and password? If so I think I will wait for it to be released as this is getting into the too difficult box

28.0 will support that. You can also remove the password authentication. The latest update to buster broke this.
modify the /etc/mosquitto/mosquitto.conf file and add this to the bottom:
allow_anonymous true
Then reboot your machine. Try it again.

Apologies for not noticing this before, but the auth parameter is expecting a Python dict. That means the key/value pairs should be quoted. auth={‘username’:’<user name>’,’password’:’<password>’}Is your version of publishMQTT.py throwing an exception during import? Thanks, Jason You must quote both the key and value pairs as I did above. You have only quoted the values. Until you do, publishMQTT.py will continue to throw a syntax error! Thanks, Jason |

I see there was a new version of Skyweather on the 7th May but the issues with mqtt stopping still occur. I can see the data being updated in the Dash app but no data is being transmitted over mqtt. I find it works sometimes after a reboot and then stops, but no amount of reboots make the mqtt data flow again.
Any ideas as to when this issue will be fixed?

Next major upgrade on SkyWeather is being worked on in June. This is one of the issues that is being addressed. Meaning MQTT Reconnection.
