... Any ideas or possible solutions to this?
The control wire "DATA_PIN 11" must be shunted . A 1K resistor on the minus power .
if the wire "DATA_PIN 11" is longer than 10 cm.

I appreciate your answer. Could you explain why is it needed and what exactly do you mean on a minus power? Do i need to pull data pin down to GND with a 1K resistor?
