Hi,  
i wish when I put the code "1122" switch is **on** if I put "1144" the switch will be in **off** state. But i didn't find the error.

Where are all your debug nodes so you can see what actual messages you are passing? This will help you locate the error by seeing where the logic diverts from what you want

Hi.

I am not getting what you are wanting to do.

Looking at the picture of the flow, there is a button, then the `Pin_unlock` node, a `verify_pin`, `check` and so on.

These go (ultimately) to the `door PIN` node which is a node to show you the state.  
(Got that bit)

But where is the pin entered?

If it is that it sends `1122` or `1144` alternatively with each button press, then I am not getting why you need the pin in the scenario.

Yeah, ok, I should maybe look at the flow, but I am just passing by and read the post.  
Then I saw the flow and what you say.

As I said, I am not getting what it is you want to do because what I am seeing isn't what you are writing/asking.

I don't want to sound dismissive. I am new at this too. Though I guess I have got a bit of practise with using NR.

Hope to hear back.

so check what messages you are sending (using a debug node) and then  
read the docs section on how to log events within a function.

@hebergeweb You should go read the info tab of the swtch node to understand what it does.

</div>

in the template(Pin\_Unlock) there is an interface of the buttons (numbers[1,2,3,4...]) where I put the code "1122" to open the door (_ui\_switch_ changed to **on** ) and the code "1144" to close the door (_ui\_switch_ changed to **off** ).  
to open it works well but to close it I have no answer the switch remains in state on.

1. you have a bug in your fundtion node
2. you need to go read up on the switch node Edit: actually strike that, instead tell us what you think the switch node does.
