The code below is working.
I think the problem was the chinese thing.
[{"id":"31f4c4ce.c844c4","type":"rpi-neopixels","z":"28f42d2c.d47122","name":"","pixels":"8","bgnd":"","fgnd":"","wipe":"40","mode":"pixels","rgb":"rgb","brightness":"100","gamma":true,"x":642.5,"y":104,"wires":[]},{"id":"8e2c17ea.77c808","type":"inject","z":"28f42d2c.d47122","name":"","topic":"","payload":"Blue","payloadType":"str","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":354,"y":90,"wires":[["31f4c4ce.c844c4"]]},{"id":"9f8a849e.b6d5c","type":"inject","z":"28f42d2c.d47122","name":"","topic":"","payload":"red","payloadType":"str","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":343,"y":154,"wires":[["31f4c4ce.c844c4"]]},{"id":"7103e3b0.bea42c","type":"inject","z":"28f42d2c.d47122","name":"","topic":"","payload":"pink","payloadType":"str","repeat":"","crontab":"","once":false,"onceDelay":0.1,"x":347,"y":219,"wires":[["31f4c4ce.c844c4"]]}]
Now need to find out how to control single pixels and stuff, tutorial links are welcome
Thanks for your help and support
