I am under home assistant supervisor.  
I would like to use an ikea control to operate a led strip (cold white and warm white).  
here is the equipment I have:  
the 2 materials work in zigbee 3.0  
 ![Capture103](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/1/b/1b0b6f409ea582363834bb506dc1d1b6829cf70f.jpeg)

it works well on lovelace to order the led strip

Now I would like to use the command via node red  
but i'm stuck

I can turn the LEDs off and on but not use the dimmer function  
can you guide me?  
here is my flow file

Sorry, can't help via Home Assistant as I don't use it. I control my LED's via MQTT using Node-RED and Zigbee2MQTT.

 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/e/8/e83c25cb70c6eb7ff69a4bf91a697d78fda47eb8.png)

Oops, sorry that's a Shelly which is controlled directly via MQTT.

No colour setting on this but rather dimming:

ok, thanks, i'll see if it works with mqtt.

Without more details, I'm still stuck. 🥴  
if I had an example flow file for dimmer working in zigbee 3.0 it would be easier. 😟

I achieve this with the zigbee2mqtt.  
But then what do I do?

 ![Capture200](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/c/c/ccf5dc38b8915ccdaca849728ec6acb9f2446795.jpeg)  
so far it only accepts this:  
{"color\_temp": 153}{"brightness": 254} for "on"  
{"color\_temp": 500}{"brightness": 0} for "off"  
{"color\_temp": X}{"brightness": Y} for X (153\>500) Y(0\>254)

I send from Node-RED -\> MQTT directly using the MQTT-out node. Look on the Zigbee2MQTT website for the commands that are allowed for each Zigbee device.

Simple example with an Ikea Bulb:

You can change the brightness by changing the payload to something like: `{"brightness": 100}`.

mqtt-out. that's it?  
 ![203](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/7/3/736b72c6a80608bd06cb91dcbc7215a4dfd6d3c3.jpeg)  
I don't see the msg.payload and msg.topic boxes 🙄

 ![200](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/e/9/e9c3e1ee1262ea2bcf58ca0e3bb4c6e8c3eb907e.jpeg)

Or is it further, in server then the message tab??

 ![201](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/f/f/ff31c865aecb8a56c6a6bfc4ce995cb8ef2e9b53.jpeg)

that's how it is, because it doesn't look like yours. 😮

I showed you an example from an inject node. That is what you send to the mqtt node.

I think you may find it helpful to take an hour to go through one of the many Node-RED from scratch tutorials/videos so that you get the hang of how data is originated, processed and output and how the different core nodes work along side each other.

ok  
I have misunderstood. You must therefore first create an injection node and transmit it to the mqtt-out.  
thank you. and I will follow your advice.
