I wrote a simple counter,

I want to reset the count to 0 whenever I press the button.
I also need it to start automatically and start counting again from 0.

But instead every click set the counter 1 step higher. If I double click it the count will go up by 2.

Go to your flow. Click on the counter node. Click on the info button in the right hand column. Scroll to the bottom.

What does it tell you?

thank you that was helpful.
I have another question: How do I stop the counter without resting it so i can watch the current count ?

How do I stop the counter without resting it so i can watch the current count ?

You can do it with that node, so you are going to have to code up a way to save the counter.

Maybe have two outputs from the counter: one goes to a ui-text node to display running count, the other goes thru some code and ends up at a ui-text node that is labeled "High Count"

Then have a button that would clear the reset the "High Count" to the running count. So you would need the msg going to the 'High Count' to go thru a switch that checked to see if the button was pushed to see if the value should be passed thru.

You could also try this with the excellent node-red-contrib-dsm. It work only with numbers though.

just inject the setup counter first. If you want it to persist across reboot you'll have to enable the context storage as per the docs.
