Thanks for the reply’s
Will play around and read some more. If i need more help al post back of not i’l close the topic.
Greetings

The “broker” witch is in the code is the name of my broker, so sould that not be in there ?

I do now receive a error aboute [%.1f °C] pasrt:

Configuration model 'miflora1.items' has errors, therefore ignoring it: [1,39]: no viable alternative at input '%'

this is the item, i removed the second item, will add it when i have it working.
Number temperature "Air Temperature" [%.1f °C] {channel="mqtt:topic:miflora:temperature"}

In the PUI i do see Generic MQTT Thing online:

Generic MQTT Thing ONLINE

Generic MQTT Thing

mqtt:topic:broker:miflora

and the MQTT Broker online:

MQTT Broker ONLINE

MQTT Broker

mqtt:broker:broker

Greetings

“---------”

"Air Temperature[%.1f °C]"

special attention needs to be paid to copying paste

Thanks all for the help, its now working.
Info for others with this problem.

my .items

Number Temperature "Air Temperature[%.1f °C]" {channel="mqtt:topic:broker:miflora:temperature"}
    Number Humidity "Humidity[%d %%]" {channel="mqtt:topic:broker:miflora:humidity"}

my .sitemap

    sitemap temp label="temp"
    {
            Frame label="temp" {


    Text item=Temperature
    Text item=Humidity


    }
    }

My .things

Bridge mqtt:broker:broker [ host="192.168.178.192", secure=false, clientid="openhab", username="openhab2", password="Mypasswd" ]
    {
      Thing topic miflora {
       Channels:
         Type number : temperature "Air Temperature"   [ stateTopic="sensor/temperature_celsius"]
         Type number : humidity "Humidity"  [stateTopic="sensor/humidity"]
        }
    }

Greetings

I do not think so

What do you mean?

you have to change

“ 
to 
 "

I just tried that, but for some reason it keeps type the wrong ones.

That’s because you are not using the code fences

Thanks, i think i now have them all the correct way

Q1:When the new MQTT binding looses its connection, it there anything I can do to trigger a reconnect? e.g. a rule, some setting in the .things file.

Q2: Is there a way to not trigger any more mqtt messages out of a rule when the Broker is disconnected? e.g can I check the status of the “actions” variable before I do an

actions.publishMqtt(“topic”,“some message”).

mqtt:broker:solace [ host="m11.cloudmqtt.com", port=11403, username="username", clientID="someClient", qos=0, password="somePW" ]

val actions = getActions(“mqtt”,“mqtt:broker:solace”)
actions.publishMQTT(“moosecabin/homeautomation/persistence”,i.name + “,” + i.state)

mqtt message

{"battery":100,"voltage":3125,"linkquality":0,"smoke":false}

  1. ASK its a BUG?
    and wats a realy bug. If the thing file include the Bride Line
Bridge mqtt:systemBroker:embedded-mqtt-broker

its disconect the embedet Broker. Or if the line include a IP information, Broker.
its only function given a new Broker Name on every new save version.

I need a little on this one - it should be fairly simple, but I cannot figure out why it isn’t working.
The issue is I can’t see the temperature in my sitemap with the new MQTT 2.4 binding

This is my config :
Things

Bridge mqtt:broker:mosquitto "local mosquitto" [ host="localhost",secure=false ]
{
        Channels:
		Type number : MQTT_BoilerRoom_1_1  "Flow"  [ stateTopic="/ESP_Easy_BoilerRoom/OneWireBus1_1/Temperature" ]
}

Items

Number  Temp1  "Temperature"  {channel="mqtt:broker:mosquitto:MQTT_BoilerRoom_1_1"}

Sitemap

Text item=Temp1	label="Temp1 [%.2f °C]"

In the openhab.log (and paperUI) I can see that the broker is online, and in the events.log I see events regarding receiving temperatures. I guess this indicates that the binding is working as expected, and the issue is related to my item/sitemap config, but I cannot figure out what I’m missing ?

openhab.log 
2019-01-01 21:07:10.250 [me.event.ThingUpdatedEvent] - Thing 'mqtt:broker:mosquitto' has been updated.
2019-01-01 21:07:10.329 [hingStatusInfoChangedEvent] - 'mqtt:broker:mosquitto' changed from OFFLINE to ONLINE
2019-01-01 21:07:10.330 [me.event.ThingUpdatedEvent] - Thing 'mqtt:broker:mosquitto' has been updated.

events.log
2019-01-01 21:28:07.413 [vent.ChannelTriggeredEvent] - mqtt:broker:mosquitto:MQTT_BoilerRoom_1_1 triggered 27.87

Any ideas ?

You did create a broker thing, after that you need to create a “Generic MQTT Thing”.

Like:

Bridge mqtt:broker:myBroker [ host="MyIP", secure=false, username="myUser", password="myPassword" ]
{
  Thing topic sonoff_1_Thing "Light_1" @ "Sonoff" {  
    Channels:
        Type switch : PowerSwitch  [ stateTopic="stat/sonoff_1/POWER" , commandTopic="cmnd/sonoff_1/POWER", on="ON", off="OFF" ]
        Type string : Version [stateTopic="stat/sonoff_1/STATUS2", transformationPattern="JSONPATH:$.StatusFWR.Version"]
      } 
}

and an item like:

Switch Stern_1 "Stern1" ["Lighting"] { channel="mqtt:topic:myBroker:sonoff_1_Thing:PowerSwitch" }

Hi Jürgen

It works :partying_face: :+1:
I really thought I had tried all combinations, but apparently there was one, I hadn’t tried

Thank you very much

Hi Jürgen

First of all thank you for your help, things are working now (thanks to you), but now I would really like to understand what I’m doing :thinking:

On this page https://www.openhab.org/blog/2018-12-16-mqtt-arrives-in-the-modern-openhab-2-x-architecture.html the thing-syntax is described with a colon (and a mqtt: in the beginning) Thing mqtt:topic:mything and you have spaces between Thing topic sonoff_1_Thing - do you know if both are valid, or is it just a typo on the blog-page?

Your example has Light_1" @ “Sonoff”, which the example on the doc page doesn’t have https://www.openhab.org/addons/bindings/mqtt.generic/ - what is the purpose of Light_1" @ “Sonoff” ?

And last but not not least… the channel part of the item is a “little” confusing - it looks like its a mix something from “bridge”:“thing”:“bridge”:“thing”:“channel” - i can’t find any documentation about channels in general. Do you know if its described somewhere, or can you explain it ?

I have tried to visualize it with this image

On the differences in syntax please see this thread.

The"Light_1" @ "Sonoff" part will label the thing as “Ligth_1” and put it under the Location “Sonoff” (visible on PaperUI Controls if at least one channel is linked to an item). Both are not required!

Once again thank you - things are finally beginning to make sense.

Apparently I wasn’t the only one who was a little bit confused about the syntax :thinking: And this was exactly was I was looking for https://www.openhab.org/docs/configuration/things.html
