Zigbee led strip dimmer

[pilou8830]

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


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.

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

No colour setting on this but rather dimming:

[pilou8830]

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

[pilou8830]

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.

[pilou8830]

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

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)

[TotallyInformation]

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}.

[pilou8830]

ok i'm testing this now.
Thank you

[pilou8830]

mqtt-out. that's it?

I don't see the msg.payload and msg.topic boxes

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

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

[TotallyInformation]

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.

[pilou8830]

@TotallyInformation

inject node

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.
