Zigbee2mqttt LED Smart Home Livarno Lux

  • Platform information:
    • Hardware: Raspberry pi4
    • OS: raspi
    • Java Runtime Environment: Openjdk 11
    • openHAB version: 3

I’m trying to configure one Zigbee LED, but I can’t figure out how to get and command the brightness.

I can turn it ON and OFF, but no success extracting the brightness out ot the MQTT message or sending the command to it

I can see the mqtt message /zigbee2mqtt/LedLidl with Payload {“brightness”:80,“color”:{“x”:0.270103566139535,“y”:0.275462785681784},“color_temp”:80,“linkquality”:31,“state”:“ON”} with MQTT.fx

Any Idea how to solve it or where to look for the error?

zigbee2mqtt.thing file

Bridge mqtt:broker:mosquitto "mosquitto" [ host="", port=1883, secure=false, username="openhab", password="" ] {
    Thing topic LedLidl "Luz Led Lidl" @ "Salón" {
            Type switch : Encendido        "Encendido"  [ 
       	    Type dimmer : Brillo "Brillo" [
                // formatBeforePublish="{ \"brightness\" : 30 }"



Group g_LuzLedLidl "Luz Led Lidl" 
Switch LuzLedLidl "Luz Led Lidl" <light> (g_luces, g_LuzLedLidl) {channel= "mqtt:topic:mosquitto:LedLidl:Encendido"} 
Dimmer LuzLedLidlBrillo "Luz Led Lidl Brillo [%d %%]" <light> (g_LuzLedLidl) {channel="mqtt:topic:LedLidl:Brillo"}

Can you link the product from this page?

Have you been successful changing brightness with mqtt.fx? According to the docs


should do the job

By the way, I recommend http://mqtt-explorer.com for debugging mqtt setup.

Sending the message via MQTT.fx works, but no success with openhab

It seems that it doesn’t send anything, when I try to change the value with one slider in my sitemap

This is commented out. Did you try some variations here? This should work:

formatBeforePublish="{ \"brightness\" : %s }"

Thats my default setup for such devices. Should also work in your case

Thing mqtt:topic:livingRoomLEDstripe "Hintergrundbeleuchtung im Wohnzimmer"{
        Type switch : state             "Zustand Hintergrundbeleuchtung"       [stateTopic = "zigbee2mqtt/livingRoomLEDstripe", transformationPattern="JS:getZigbeeONOFFstate.js", commandTopic = "zigbee2mqtt/livingRoomLEDstripe/set/state", on="on", off="off"]
        Type number : linkquality       "Link Hintergrundbeleuchtung"          [stateTopic = "zigbee2mqtt/livingRoomLEDstripe", transformationPattern="JS:normZigbeeLink.js"]
        Type number : brightness        "Helligkeit Hintergrundbeleuchtung"    [stateTopic = "zigbee2mqtt/livingRoomLEDstripe", transformationPattern="JSONPATH:$.brightness", commandTopic = "zigbee2mqtt/livingRoomLEDstripe/set/brightness"]

I think it should be “…/set/brightness” in the command topic of the dimmer channel

Yes I tried it. No success

You may be running into a known bug with Things files - try restarting openHAB and try again. If that doesn’t work, please show us your latest configuration.
