Can someone advise me on the following please? I have an Bluetooth beacon and use geofency on my phone to call an http endpoint in nodered when the phone comes near to the beacon, and as well wenn it leaves the vicinity of the beacon (check-in / check-out). Now while the phone is near the beacon, …

So use a trigger node in combination. e.g. [{"id":"9b66cd38.78f058","type":"inject","z":"c791cbc0.84f648","name":"","props":[{"p":"payload.dir","v":"in","vt":"str"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"","once":false,"onceDelay":0.1,"topic":"","x":140,"y":720,"wires":[["9ca474fb.4174a"…

Try using the filter/rbe node. It should be able to filter messages until a property value changes.

Thanks, I don't think that alone will solve it because the fluttering signal does represent changes. However, I just found a node which seems to be designed for doing exactly what I want: node-red-contrib-debounce-leading-trailing. Will give it a try.

If you provide more info on incoming msg's, we could give example of how to use filter node

It basically is either msg.payload.dir === "in" or msg.payload.dir === "out" But while being "in", it may happen that an "out" appears, followed by another "in" within 10s. In that case, no change would happen. If however no "in" follows the "out" within 10s, then the change happens. thank you!

that's pretty clever. Thank you!

Have a look at the delay node too.
