I want to count the amount of messages, store them and then send the total every 10 seconds to the mqtt broker.  
Like the first signal on the broker is 0, then 50, then 100......

I got the following flow but it just send every 10 seconds a message of 1

```auto

You appear to be using a contrib node in your flow. What counter node are you using?

Add more debug nodes along your flow to understand what messages are being passed along your flow.

Yes, i found the problem. The payload was the message and the count so "1 300", "0 600"
