Issue to add first sonoff / mqtt -switch in a sitemap

Add-ons Bindings
1

Hello,
I just try to add my first sonoff into a sitemap, from shell the connection and receiving mqtt is fine.
On the shell I get the following answer when pressing the physical button on the sonoff:

stat/sonoff/sonoff-switch-02/RESULT {“POWER”:“OFF”}
stat/sonoff/sonoff-switch-02/POWER OFF
stat/sonoff/sonoff-switch-02/RESULT {“POWER”:“ON”}
stat/sonoff/sonoff-switch-02/POWER ON

In my Items-file I add:

    Switch Switch_TV_Simulation
      "TV Simulator"
      [ "Switchable" ]
      {mqtt=">[broker:cmnd/sonoff/sonoff-switch-02/POWER:command:*:default], <[broker:cmnd/sonoff/sonoff-
    switch-02/POWER:state:default]" }

And in the sitemap I simple add:

 Switch item=Switch_TV_Simulation label="TV Simulation"

Now I see the switch-button in the sitemap, but nothing happens (nothing when pressing the physical button, niting when pressing the button in oH).

In the log from Visual Studio I get: “Received HTTP POST request at ‘items/Switch_TV_Simulation’ for the unknown item ‘Switch_TV_Simulation’.”

Actuall I don’t understand … shurly a"simple" mistake/missunderstanding on my side …

Which binding did you install? mqttv1 or mqttv2?
So you have a MQTT Broker installed and running?

In PaperUI I see: binding-mqtt1 - 1.12.0

Yes, it’s running, I allready use mqtt to get the energy (water & electricity) consumption signals (they are sendet by shell script from another Raspberry, and this works).
So I think it’s a syntax or logical error on my side (2 month ago I add my last item :wink: )

Hi, try it this way:

Switch    Sonoff_socket_01 "Wohnzimmer LED 1 [MAP(de.map):%s]"  <lamp_globe_light>      (EG_Wohnen,gPlugSwitch,gSonoff)  { mqtt=">[yourbroker:cmnd/schaltdose01/power:command:*:default],
                                                                                                                                 <[yourbroker:stat/schaltdose01/POWER:state:default]" }

I saw my (first?) mistake,
I used: {mqtt=">[broker:cmnd/sonoff/…
But I think (saw in log and in other mqtt item) I have to user: {mqtt=">[**mosquitto:stat/**sonoff/…

In log I see:
…
_Could not update element with key tags:Switch_TV_Simulation in ManagedMetadataProviderImpl, because it does not exists.

And when controlling mqtt I see the mqtt was send (+) when pusing the button in oH, but the sonoff did not switch :frowning:
(+) stat/sonoff/sonoff-switch-02/POWER OFF
stat/sonoff/sonoff-switch-02/POWER ON

if mosquitto is the name of your broker, that’s correct. This is the name you gave it in your mqtt.cfg

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

The angle should look to the left for the stat-command, like this <

and of course delete the metadata [ “Switchable” ] for testing. I think there is another problem too.

To send a command for turning on the switch use cmnd not stat

You item should look like this:

Switch Switch_TV_Simulation "TV Simulator" ["Lighting"]
      { mqtt=">[broker:cmnd/sonoff/sonoff-switch-02/POWER:command:*:default], <[broker:stat/sonoff/sonoff-switch-02/POWER:state:default]" }

Just make sure to use the correct broker name as @fibu-freak mentioned above.

Example if the broker name is mosquitto the item should look like this:

Switch Switch_TV_Simulation "TV Simulator" ["Lighting"]
      { mqtt=">[mosquitto:cmnd/sonoff/sonoff-switch-02/POWER:command:*:default], <[mosquitto:stat/sonoff/sonoff-switch-02/POWER:state:default]" }
8

that’s it, as @H102 described. The first mqtt-command sends the command (cmnd) to switch on or off, and the second command (stat) receives if update was done.
BTW for what purposes you need the metadata ?

Thanks H102, now it works , somewhere I found (or saw) this example with two “stat’s” and use it …

Peter, what do you mean with “or what purposes you need the metadata ?” ?

Glad you have it working.:+1:

The tags in the items e.g. [ “Lighting” ]. They are used to allow voice control with devices like Alexa. If you have no need for this you can remove the tag.
