Help with MQTT/Mosquitto/HA and Windows

Installation Home Assistant OS
1

I have downloaded mosquitto exe and it’s running on the server
I can use pub/sub to publish/subscribe the messages from another computer successfully
I’ve added this in the config:

mqtt:  
  broker: 192.168.1.63  
  port: 1883  
  client_id: home-assistant-1

And this as sensor…

- platform: mqtt  
    state_topic: "bruh/sensornode1"  
    name: "SN1 Temperature"  
    unit_of_measurement: "°F"  
    value_template: '{{ value_json.temperature | round(1) }}'

But… if I publish a message like this

mosquitto_pub.exe -h 192.168.1.63 -t "bruh/sensordone1" -m "{ "temperature" : "14" , "motion" : "ON" }"

I cannot read the value in the sensor.

Any idea?

I just found out about mqtt explorer yesterday. Start it on client machine (e.g. windows) and then point to your broker and you can see “everything”.

3

Did you allow the windows firewall access to 1883 ?

4

Could you elaborate this a bit more?

Did you try it with HA on Windows?

5

As I said, I can communicate with MQTT broker from another PC :slight_smile:

6

Then the next step is to see if HA connects to your broker.

Go to developer tools -> Mqtt

enter # under ‘topics to subscribe to’, hit ‘start listening’

then, under ‘publish a packet’, enter test under topic ‘topic’, and ‘on’ next to payload, and hit ‘publish’

See if you get any response under ‘listen to a topic’

@francisp I can listen to MQTT messages if I start listening from MQTT page under developer.

So I send mosquitto_pub and I read the payload in the HA page.

But sensors doesn’t seems to be updated

8

@francisp any idea?

9

If you listen to bruh/sensornode1 , do you see results ?

10

No… the problem seems to be the “/”… If I send message to bruh and listen to bruh I can get it…

but not with bruh/sensornode1

11

Fixed it!

Thanks @francisp

A stupid typo in the mosquito_pub message!!!

Do I need username and password?

If it works, no
