KNX & Viessmann Binding API & Visualization Panels Issues

accumulator · June 26, 2026, 2:01pm

Hi All,

I had and old viessmann vitodens WB2 (original) boiler, with a vitocom KNX gateway to V bus. This was being controlled by a visualization panel ABB Comfort Touch Panel and it worked fine, if you increased the hot water temp on the vis panel it would also update openhab, and vice versa. I have now replaced the boiler with new WB2 version, and because I dont want to spend 900 euro on the viessmann KNX to Wago Canopen gateway, I have opted to use the Viessmann API. The Viessmann app works fine and also openhab links to it. However, I cant seem to get any of the information from the API via openhab to the KNX bus.

I have removed the old vitocom KNX gateway from ETS, and unloaded it, but kept the same ga’s definitions and the visu panel, which are text based. (I started OH 2.5, but now on OH 5.1). However, I used the main ui to obtain channels from the Viessmann thing, and linked each channel item corresponding to say boiler temp to the previous. It is strange though, the Visu panel never comes up as offline or online, in the list of KNX things, or even list under things. I understand they don’t? Is that correct? In the visu panel, and I can control the Set Heating Temp, through the Visu panel and this updates perfectly on openhab, even though in openhab KNX things its not shown.

Do you think its case of creating a dummy Device in order to get the openhab and viessmann api talking to KNX. Is it my IP KNX gateway a problem, it is the line filter tables in KNX? My KNX Ip router is based on line 1, and the visu panel is on line 2?

Any help would be appreciated on this.

Many thanks

Hello first start by posting all your configs here so we can see what you are dealing with its really hard to get an answer from people unless there is someone with the exact same setup as you and by change he likes to read the forums and stumble upon your post …

Ok, which configs do you need to look at, for me to post? Perhaps @Udo_Hartmann could help, being a knx expert and also knowledgeable about viessmann bindings?

Udo_Hartmann · June 28, 2026, 10:08pm

Well, it depends on how the items are linked to the Thing Channels.
As you want the state of a openHAB Item to be sent to knx, you will have to use control-Channels (for example number-control, switch-control and so on).
the *-control will result in a command to the corresponding GA whenever the linked item gets updated.
Please be aware that only the first GA is used to send data.

Hi Udo,

Thanks, but where do I set up control channels in the Main UI,

Sorry Im lost?

Simply change the channel-type:

Thing device N8 "Knx Set Point Temp" [] // delete the address, as this is no longer a real device
    {
        Type number-control : Channel_008 "Ext Air Temp"             [ga="9.001:13/2/0"]
        Type number-control : Channel_009 "DHW Temp Actual"          [ga="9.001:13/2/6"]
        Type number-control : Channel_010 "DHW Temp Adjust"          [ga="9.001:13/2/7"]

        Type number-control : Channel_012 "Adj Boiler Slope Curve"   [ga="9.001:13/2/4"]
        Type number-control : Channel_013 "Adj Boiler Curve Shift"   [ga="9.002:13/2/3"]
        Type switch-control : Channel_014 "Boiler Error Alarm"       [ga="13/2/12"]
        Type string-control : Channel_015 "Error Message Fr Boiler"  [ga="13/2/11"]
        Type number-control : Channel_314 "Heating Set Point"        [ga="9.001:13/1/1"]
        Type number-control : Channel_315 "Comfort Mode"             [ga="5.001:13/1/0"]
        Type number-control : Channel_316 "Night Mode"               [ga="5.001:13/1/2"]
        Type number-control : Channel_317 "Frost Protection"         [ga="5.001:13/1/102"]
        Type number-control : Channel_318 "Boiler Operation Mode"    [ga="5.010:13/2/8"]
    }

Obviously, you have to link the Items to the new Channels as well (so not only the knx channel but also the viessmann channel)

accumulator · June 29, 2026, 10:26am

Oh ok, its thats simple then. When linking the channels, as you can see, I have linked them via the Main UI. Can this done with text files, for the viessmann channel. I saw a post from you discussing with the creator of the viessmann 3rd party binding, that you were use to using text based configs, and why the binding couldnt be set up using text based files?

Udo_Hartmann · June 29, 2026, 11:37am

Of course you can link as many channels to as many items as you want, no matter if using Main UI or Text files, but it’s definitely better to use only one configuration option, so either text or Main UI.
In question of the viessmann binding, there was an issue that it wasn’t possible to create the thing completely from text files. But afaik that’s no longer true.

Bridge viessmann:account:bridge "Viessmann Bridge" [
    apiKey="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", // the api key, created in the viessmann developer portal
    user="your.email@address.com",             // the mailadress for the viessmann developer portal account
    password="xxx"                             // the password for the account
   ] {
    Bridge gateway vitoconnect "Viessmann Gateway VitoconnectOPTO2" [
      gatewaySerial="12345678901234567",       // the serial number
      installationId="123456"                  // the installation id
   ] {
      Thing device heizung "Heizung" [
         deviceId="0"
      ]
      Thing device HeatDemandControl "Heizungsanforderung" [
         deviceId="HeatDemandControl"
      ]
      Thing device RoomControl_1 "Temperatursteuerung" [
         deviceId="RoomControl-1"
      ]
   }
}

I got the serial and installation id by auto discovery from openHAB, but set it up via things file as shown here.

All channels are auto discovered, so you’ll have to get them e.g. via VSCode to use them in items-files:

And each of these items can be linked in parallel to another channel as well, like that:

Number:Temperature   HeatSensorsTemperatureOutside "Outside Temperatur Sensor" (gHeizung) ["Measurement"] {channel="viessmann:device:bridge:vitoconnect:heizung:heating-sensors-temperature-outside", channel="knx:device:INSIDECONTROL:N8:Channel_008", unit="°C", stateDescription=""[pattern="%.1f °C"]}

given that your knx bridge is knx:<ip or serial>:INSIDECONTROL
