Aquara Wall Switch OH2.4 -> OH3.4 using MQTT Transformation

For some weeks I migrate from OH2.4 to OH3.4 and solved many problems. But the last problem is to migrate my Aquara Wall Switches. I use in background Zigbee2MQTT and a JS-Transformation. Here is my working OH2.4 setup:

Switch AquaraKuecheLeft    "LED Links"     (Aquara) ["Lighting"]     { mqtt="<[mosquitto:zigbee2mqtt/0x00158d00031e371c:command:JS(getZigbeeXiaomiLeftClick.js)]" }
Switch AquaraKuecheMiddle  "LED Mitte"     (Aquara) ["Lighting"]     { mqtt="<[mosquitto:zigbee2mqtt/0x00158d00031e371c:command:JS(getZigbeeXiaomiDoubleClick.js)]" }
Switch AquaraKuecheRight   "LED Rechts"    (Aquara) ["Lighting"]     { mqtt="<[mosquitto:zigbee2mqtt/0x00158d00031e371c:command:JS(getZigbeeXiaomiRightClick.js)]" }

The corresponding transformation looks like this (DoubleClick “both” instead of “left” and RightClick “right”):

(function(x){
 
  var result = "none";
 
  var json = JSON.parse (x);  
  try {
    if (json.click == "left") {
      //if (json.linkquality != 0) {
        result = "ON";
      //}
    }
  }
  catch(e) {
    result = "none";
  }

  return result;
    
})(input)

The message which I get via MQTT is for example:

zigbee2mqtt/0x00158d00031e371c {"battery":100,"voltage":3005,"linkquality":99,"click":"left"}
zigbee2mqtt/0x00158d00031e371c {"battery":100,"voltage":3005,"linkquality":94,"click":"right"}
zigbee2mqtt/0x00158d00031e371c {"battery":100,"voltage":3005,"linkquality":94,"click":"both"}

And now the OH3.4 setup, which does not work:

Type switch : AquaraKuecheLeft  "LED Links"           [ stateTopic="zigbee2mqtt/0x00158d00031e371c", transformationPattern="JS:getZigbeeXiaomiLeftClick.js" ]
Type switch : AquaraKuecheMiddle "LED Mitte"             [ stateTopic="zigbee2mqtt/0x00158d00031e371c", transformationPattern="JS:getZigbeeXiaomiDoubleClick.js" ]
Type switch : AquaraKuecheRight "LED Rechts"            [ stateTopic="zigbee2mqtt/0x00158d00031e371c", transformationPattern="JS:getZigbeeXiaomiRightClick.js" ]

It seems, that the JS-Transformation will not be called, because the assigned switch item is not switched nor receives any command/update. But I get warnings (also with right and left):

2023-01-15 13:59:21.150 [WARN ] [ab.binding.mqtt.generic.ChannelState] - Command 'both' from channel 'mqtt:topic:zigbee:AquaraKuecheRight' not supported by type 'OnOffValue': No enum constant org.openhab.core.library.types.OnOffType.both

I tried also (without success):

  • direkt JSON access together with on:
on="left", transformationPattern="JSONPATH:$.click"
  • additional using of Regex:
on="left", transformationPattern="REGEX:(*left*)∩JSONPATH:$.click"

I need some ideas or hints, how I can migrate that. I dont want change my infrastructure using MQTT and Zigbee2MQTT

Thanks

The error message is about the channel / thing, but you are looking into your item definition.

Maybe have a look into your mqtt thing definition.
I would apply the transformation at a channel level, then you should have no issues linking an item

The OP has shown their Thing definition, not the Item definition. Or more precisely: they’ve shown the Thing Channel configuration.

As an aside @Dojokun, are you aware that your example JSON seems to come from a different topic to that you’ve configured in openHAB?

Sorry. This is a copy paste error. The ID’s are the same. I will correct in my original post.

In openHAB, please go to Help & About → Technical Information → View details and copy and paste all the information here in between code fences.

You can do this with the transformation.

Thanks. The experimental switch, which is described there, works on my system. Now I have to deal with the new syntax.

It works. Had to rewrite my rules and change the items from switch to string.
