Trouble creating an item that display value of Sonoff in sitemap

[zzzz (Augis)]

Hello, I’m having issues with getting the input from MQTT to my sitemap, it works all fine when i use console commands like:

    mosquitto_sub -d -t /zzzz/relay/relay

    mosquitto_pub -t /zzzz/relay/relay/gpio/12 -m 1

This all works fine, but when I do

Contact zzzz { mqtt="<[broker:/zzzz/relay/relay:command:ON:1]" }

in my items file and then add

Text item=zzzz

to my sitemap it doesn’t display the value

[george.erhan]

Try this:

Contact zzzz "zzzz [%s]" { mqtt="<[broker:/zzzz/relay/relay:command:ON:1]" }

or

Text item=zzzz label="zzzz [%s]"

[zzzz (Augis)]

Now I can see “zzzz {-}” instead of "zzzz {blank}"
Didn’t help, could it be the mqtt.conf file?
Here is a copy of it

#

# Define your MQTT broker connections here for use in the MQTT Binding or MQTT

# Persistence bundles. Replace <broker> with an ID you choose.

#

# URL to the MQTT broker, e.g. tcp://localhost:1883 or ssl://localhost:8883

broker.url=tcp://1.1.1.67:1883

# Optional. Client id (max 23 chars) to use when connecting to the broker.

# If not provided a random default is generated.

#broker.clientId=OPENHAB2

# Optional. True or false. If set to true, allows the use of clientId values

# up to 65535 characters long. Defaults to false.

# NOTE: clientId values longer than 23 characters may not be supported by all

# MQTT servers. Check the server documentation.

#<broker>.allowLongerClientIds=false

# Optional. User id to authenticate with the broker.

broker.url.user=openhabian

# Optional. Password to authenticate with the broker.

broker.url.pwd=adminas12

# Optional. Set the quality of service level for sending messages to this broker.

# Possible values are 0 (Deliver at most once),1 (Deliver at least once) or 2

# (Deliver exactly once). Defaults to 0.

#<broker>.qos=<qos>

# Optional. True or false. Defines if the broker should retain the messages sent to

# it. Defaults to false.

#mqtt:broker.retain=true

# Optional. True or false. Defines if messages are published asynchronously or

# synchronously. Defaults to true.

#mqtt:broker.async=false

# Optional. Defines the last will and testament that is sent when this client goes offline

# Format: topic:message:qos:retained <br/>

#<broker>.lwt=<last will definition>

P.S I’m available to see the values in MQTT.fx

@zzzz

broker.url=tcp://1.1.1.67:1883

are you sure your broker ip is 1.1.1.67?. if it’s localhost, type:

broker.url=tcp://localhost:1883

[george.erhan]

Is your broker installed on the same machine as OH?

[zzzz (Augis)]

Yes

[george.erhan]

Is the broker setup for accepting the credentials username and password?
check the logs via

ssh -p 8101 openhab@localhost
log:tail

to see if OH connects to the broker
Also, try changing mqtt.cfg if credentials are set correct in the broker:

broker.user=openhabian

broker.pwd=adminas12

[zzzz (Augis)]

I’m trying it right now

[zzzz (Augis)]

I tried passwords adminas12 [ my user password ] and openhabian

[george.erhan]

I think you are missing the point. The broker credentials has nothing to do with the ssh connection to the karaf console. The karaf console connection at openhab@localhost has the default password habopen
Take a look here
And also take a look here.
So, please read these documents first.

Now I’m getting

Take a look here:

MQTT config under OH2

@Rob_Pope I had a similar problem in the past… It was due to OpenHab 2 loading up the default mqtt.cfg config file (with the sample <broker> name)… it was my mistake since I removed the comments from the lines without adjusting the broker name… After I fixed the mistake, the <broker> info still remained (as a second broker) in OH2 “internal database” (I don’t know how to call it :)) and was causing errors because all other parameters for <broker> were null. Try to check with the Karaf Console …

SOLVED IT
Thank you for your help

The issue was that I set a password while installing Mosquitto from

sudo openhabian-config

I left it blank and it worked, also I’m using a value of 1 and 0 so I needed to do

String zzzz "zzzz [%s]" { mqtt="<[broker:/zzzz/mygtukas/Switch:state:default]" }

Instead of

Contact zzzz "zzzz [%s]" { mqtt="<[broker:/zzzz/mygtukas/Switch:state:default]" }

Thank You for your help, couldn’t solve it without you.
