Hi All, I have a reed switch on a gate, when the switch triggers it updates on my device from false, to true. Is there a way that when this occurs, that it populates a node? Intention is to get this information into OpenHAB as a Contact Item (so, OPEN/CLOSED) Here is the debug from the door 07/1…

[image] dastrix: Is there a way that when this occurs, that it populates a node? What do you mean by 'populates a node'. The normal way to pass information to a node is to send it a message.

What im confused about is what I need to use when the gate opens/triggers and the reed switch changes from closed to open. How do I get that message and put it into a node?

How did you get the message that you showed us above - did it get sent automatically when the switch was activated, or did you somehow request the current status?

I used this template uhppoted/node-red-contrib-uhppoted/blob/master/examples/basic/7-doors.json [ { "id": "86bbf50e.a7f188", "type": "tab", "label": "7-doors", "disabled": false, "info": "# door control: basic examples\n\nBasic examples for …

That flow has three Inject nodes, each labelled "test". The there are the three nodes "get door control", "set door control" and "open door". I don't know which of these gives you the data you posted above since I do not have a UHPPOTE TCP/IP Wiegand access controller board. However, you can set t…

Thanks, but can't NR react to the code changing (Closed to Open) or must it use some kind of timer like you said ?

All I have to go on is what you've told us. I don't have the slightest idea what you mean by "the code changing". There are nodes which watch for an event and send a message when a change occurs. An example is the Raspberry PI GPIO In node. Perhaps one of the UHPPOTE nodes does that? I don't know. …

From what I can tell, you may have better luck taking a look at this example for a closer to real-time data feed.

[image] dastrix: rather than the device sending a message to NR upon it changing (which it wouldnt do) Most devices do send data when they change state. What device are you using and how is it connected to the system?

Changing, by this i mean the door ie from Closed to Open. But I guess this is all NR polling the device, rather than the device sending a message to NR upon it changing (which it wouldnt do)

I dont think NR is the right way to do it.
