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](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](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/a/0/a097760d662be04ac93910b63295a3654ad5bd50.png)

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

![mqtt_controller](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/5/6/563f2cf30a9bd8a934b69b601d618cfcbe069244.png)

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](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/b/f/bf58aac246afec1c7bbaf3cec093c69e93a80c00.png)

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}](http://192.168.2.84/control?cmd=%7B%7Bpayload%7D)}

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 🙂

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](https://espeasy.readthedocs.io/en/latest/Reference/Command.html#command-a-specific-task-for-multiple-instances-of-a-plugin) (do a search for "NeoPixel")  
`brightness: 0..255 (only applicable when using GRBW LEDs)`  
so try removing the last 0
