Intesis me-ac-knx-1-v2


I’m still struggling with my me-ac-knx-1-v2. I’ve got a Mitsubishi Aircon and still try to integrate it into openhab.

I’m just not advanced enought to integrate it… ON/OFF works although :slight_smile:

Can anybody help me integrate it in my things / items and maybe in sitemap or point me in the right direction?

Screenshots attached.

What I want to do:

  • Switch on and off
  • Set temperature
  • Read actual Temperature
  • Switch through modes (Auto / Cool / Dry / Heat / Fan)
  • Switch through fan speeds
  • Switch through Vane Positions including swing

Thank you very very much in advance!

Ok, I got a step further… right now ON/OFF and Fan Speed is working…

And now I’m trying to build the sitemap…


Frame label="Klimaanlage" {
Switch item=EG_Buero_Klima_AnAus label="An / Aus" icon="snow"
Switch item=EG_Buero_Klima_FanSpeed_Num label="Lüfterstufe" icon="fan" mappings=[1="1", 2="2", 3="3", 4="4"]

Now i’m trying to get the “Mode” up and running… but it seems that I’m running in exactly this problem.

Selection item=EG_Buero_Klima_Modus label="Modus" icon="settings" mappings=[0="Auto", 1="Heat", 3="Cool", 9="Fan", 14="Dry"]

As you kann see in my “things” I try to use DPT 20.015.

I tried with Number, Selection and so on in my sitemap. Even as Dimmer and String in items and things but I always get:

21:01:25.395 [INFO ] [smarthome.event.ItemCommandEvent     ] - Item 'EG_Buero_Klima_Modus' received command 0
21:01:25.403 [INFO ] [arthome.event.ItemStatePredictedEvent] - EG_Buero_Klima_Modus predicted to become 0
21:01:25.408 [DEBUG] [x.internal.handler.DeviceThingHandler] - None of the configured GAs on channel 'knx:device:GIRA2167:ME-AC-KNK-1-V2_22:Kanal_22_B' could handle the command '0' of type 'DecimalType'

Anyone got a hint?

Change the DPT from 20.015 to 5.005! It will work, I have many ME AC Intesisbox Interfaces and they all work fine.
Try your setup in things like this:

Type    number  :       Kanal_22_B      "Klimaanlage Büro Modus [%s]"                   [ ga="5.005:2/6/1+<2/6/1" ]

Something that might not be working with this interface is that it has a control and a status object which you should pair in different ga’s (2/6/1+ a new one for status): object 1 for control and object 47 (or 44 depending on parameter configuration) for status.

Nice! Worked instantly!

Have you got a full example of an indoor unit (sitemap and things)?

No, sorry, no sitemaps here! As for a things file, it very much depends on the parameter configuration of your interface.
Glad I could help!

Hello Alex,

I’ve seen you use the KNX Datatype 1.007 for Increase/Decrease some Values.
How you visualize these items? (and how to connect them in a propper way with the visu?)
-> I need this kind of application, to adjust my setpoint on my MDT Heating Actuator
