Processing Time-Series Sensor Data

[hamin123]

Hi,

I am looking for a filter node that would give me output when it receives N number of inputs e.g. 1 for a specific message.
For example, I have a dry contact on port 0 and it gives output every second. Now, if port 0 is "On" or "1" for 5 seconds or more then filter node gives me "1", otherwise it should not give any output.
Do, we have any such node, if yes can you share some example or tutorial.

Regards,

The standard nodes can help here, and in this case you can use the trigger node that can "hold" the message for x time. Send a msg.reset to it if value != On or 1.

Example flow:
