Hi all!

I have a simple condition check nodes. The chain is like this:

suncalc --\> switch --\> sonoff http on or off --\> function to send me a telegram message

The chains works ok but it is working in a repeating loop all the time and send me messages every one minute.

Any clues to stop that loop and only check when condition is true?

From the documentation:

```auto
The node provide two outputs. The first output emits a msg.payload of 1 or 0 every minute depending if day-time (1) or night-time (0).

The second output emits only on the transition between night to day (-> 1) or day to night (-> 0).

```

As you are using the top output, one payload every minute. Normal.  
If you want to have only when it is a transition, down output.
