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

Last time it came up http://forum.mysensors.org/topic/1148/need-help-with-turning-a-led-on-off-with-openhab-and-mqtt/4

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