I wrote this tutorial guide a few years ago for my IoT students.
Some of the material might be useful to you. Here's a link to the PDF.

http://resources-area.co.uk/node-red-flows/controlling_neopixels.pdf

I've just seen that the MQTT topic reference (in the Tutorial) is /node91/cmd
You don't need the initial forward slash, so it should be... node91/cmd
Obviously change the node ref to match your ESP8266 device.
Make sure in ESPeasy you subscribe to the same topic spelling/syntax.

Here's how I setup my Wemos D1 Mini. I give each device a unique Unit Name. e.g. node31

unit_name

Then in the Controllers tab I enter %sysname%/# in the Controller Subscribe box.

mqtt_controller

Hope it works for you.

How do you have the device defined in ESPEasy? Get into ESPEasy and go to the 'Device' tab then edit the device and do a screen print of it's settings and add it to a reply.

Might be worth checking your MQTT Controller settings inside ESPeasy.
This is what my setup looks like...

controller_settings

And what does your circuit look like? A photo and circuit diagram would be useful.

sorry for the late response,

an HTTP request node works perfect with the payload
http://192.168.2.84/control?cmd={{payload}}

the only thin that is strange it will not accept node red messages via MQTT
not with domoticz or with Home assistant

I don't know but i think it is due that i do something wrong with sending nodes :slight_smile:

also no ctr(idx) is posible to add to a let so how to address that port?

what is the format of the payload (i.e. the contents of {{payload}})

You are sending this:
NeoPixel,1,255,165,0,0
according to the ESPEasy documentation (do a search for "NeoPixel")
brightness: 0..255 (only applicable when using GRBW LEDs)
so try removing the last 0
