Hallo,  
ich habe mehrer Variablen angelegt und bekomme es einfach nicht hin.  
Warum geht das OR nicht auf true sondern bleibt auf "unkown"?

Wenn ich das erste Und Glied so lasse und das zweite UND Glied weg nehme und nur eine Variable auf das OR Glied gebe, funktioniert alles. Mit zwei und Gliedern nicht.

Hi and welcome to the Node-RED community. Unfortunately, while there are some German speaking users here, most of us speak English and would only have to rely on Google Translate.

It helps if you explain what nodes you are using and what you are trying to achieve.

Ok then in english This is just a test setup. The variables are logical with true and false and the picture shows the test setup.

Node-RED is generally asynchronous though so msg's arrive at your logic nodes (I assume that's what they are?) in any order which isn't predictable. That is why Node-RED doesn't allow multiple input channels. It is impossible to predict in what order things will arrive.

Since it is only a test setup, I created the variables without sensors behind them. I turn them true or false manually.  
But the order shouldn't matter for an OR.  
In my setup, both AND are true, and yet the OR behind them says unkown. I do not understand.

this test setup, on the other hand, works

You need to look into context or flow saves. The nodes do not work how you think they work. One message at a time comes in and there is no "memory" to the inputs.

Or possibly an array, or a message with multiple payloads or topics, or possibly other options someone comes up with.

Are you using node-red-contrib-boolean-logic? If so then the node should remember the states of other inputs (as identified by the topics). If you think this isn't working then export the non-working flow and post it here, along with instructions on how to trigger the fault, so we can try it. See [this post](https://discourse.nodered.org/t/how-to-share-code-or-flow-json/506) on how to post a flow here.

Is it really necessary to have that many nodes to illustrate a problem with the node? I would have thought a couple of injects, maybe a couple of Change nodes and the bool node and debug should be enough.

You still have much too many nodes, including iobroker nodes that I have no idea what they are. The most you should need is something like  
 ![image](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/3/4/340017d025233d0e77964767e48417af6367310a.png)

Along with a description of what to press to see the problem.

When pasting in a flow please also select Compact so that it appears on one line in the post, that makes it easier to mark and copy. Thanks.

Have you tried putting a `debug` node (set to display the 'Complete msg object') on the output of the three logic nodes to see what you have?

Give the debug nodes different names so you can follow the debug output more easily.  
Also, as I said earlier, just test one node at a time, starting with And gates, when they are working ok move on to the Or node

And make sure you read the INFO tab and understand how the nodes work (hini hint)
