I made a night light for my son and just used V_VARs
I used the fastLED library And this code to decode from 255,255,255 that I was sending from the controller

Probably we could open a permanent thread where we can post our experiences with different aliexpress shops regarding nrf24l01+?

I'd be interested to see a list of "good" sellers from aliexpress and not just for the radios. It seems like the store links just point to the cheapest one with free shipping some times. I haven't bought enough stuff to get burnt (7 orders of which 2 have come in and the rest should be in a week or 2) but it is one of the things that keeps me wary.

I have the 16 LED version and 5 of the diffused LEDs. So far I've only ended up using 2 of the diffused LEDs for a sleep light for my 4yr old.

Haven't found any other real uses for them. I've thought of getting some of the strips and doing lighting since then I wouldn't need to replace bulbs/switches but so far I have been unable to get wife approval.

@HarryDutch

I wasn't saying don't look at the problem. I think Node to Node communication should work.

It just this comic
XKCD Comic
comes to mind

At a certain point you have to realize you are solving the problem out of principle (which is a valid reason) rather than to solve the problem.

I just finished something similar. I used a Ws2812B LED so it can change colors.

And Openhab items

Switch Light "On/OFF" (gKR) {mqtt=">[mysensors:/MyMQTT/20/2/V_LIGHT:command:ON:1],>[mysensors:/MyMQTT/20/2/V_LIGHT:command:OFF:0]"}
String KidLight (All) {mqtt=">[mysensors:/MyMQTT/20/1/V_VAR1:command:*:default"}
Color  RGBKidLight  "Kid Light"   (All,gKR)

and openhab.rule

import org.openhab.core.library.types.*
import org.openhab.model.script.actions.*


rule "Set RGB value RGBKidLight"
when
        Item RGBKidLight changed
then
		val hsbValue = RGBKidLight.state as HSBType

		val brightness = hsbValue.brightness.intValue  
		val redValue   = ((((hsbValue.red.intValue * 255) / 100) * brightness) / 100).toString  
		val greenValue = ((((hsbValue.green.intValue * 255) / 100) * brightness) / 100).toString  
		val blueValue  = ((((hsbValue.blue.intValue *255) / 100) * brightness) / 100).toString  

		val color = redValue + "," + greenValue + "," + blueValue  

		sendCommand( KidLight, color )
end
