Hello everybody,  
I have built a flow to increase the color temperature of a Hue group. The point is that this flow is increasing the ct automatically, somehow I have got a feedback.

The HueMagic Group Node:

The JS-Code:

```auto
var p = msg.payload;
var ct = p.colorTemp;

if (ct > 460) {
    ct = 153;
    msg.payload = {
        "colorTemp": ct
    };
} else {
    msg.payload = {
        "incrementColorTemp": 40
    };
}

return msg;

```

1. question: how do I stop the feedback-loop?
2. question: what does the uncommented checkbox do?
3. question: what ist the intension of the checkbox "Ignore messages"?

I appreciate any statements, thank you!

Best,  
Timo
