Hello everybody i know this Theme About Adding a delay in a function but im new and i Need some help.

In my Function "Katze kommt/geht " i Need a delay of 5Sec after the return of the msg1 and msg2. So only the first Sensor who was activatet will return the msg and after the 5Seconds ist possible that the second Sensor activates = return msg2 = 5sec delay.

i hope someone can help me thank you and sry for the bad english 😕

Hello @Derluchs, welcome to the Node-RED forum

Please have a look in this topic on how to share flows in the forum. We need that you reformat yor post so we can import and test your flow to provide the best advice.

The easiest way to do that is to click the 'Preformatted Text' button in the toolbar: [image] Then paste in your code or flow json. You should end up with three back-tick characters - ``` - on their own line before and after the code. On standard US English keyboards, this is on the same key as the ~ character. Using the backticks will ens…

In general, you need to use the async setTimeout function to do this. It is standard JavaScript. You can use node.send inside the function so that it is sent at the right point.

If you send them on different outputs from the function node then you can use a Delay node to delay one of them.

this isnt working because one sensor is on the front of a door and the other one on the back and i want to Count with a Ultrasonic sensor how many people are comming in or going out.  
When Sensor1 \> Sensor 2 return +1  
when Sensor2 \> Sensor 1 return -1

I think you need to explain the sequence of events and what the data is in order that we can understand what you are asking.
