Sorry for the simple question but trying to automate something in node red based on presence detection...I started with and event state node but someone helping me on a forum is suggesting a trigger state node?

Not sure why i would use one rather than the other, its just scraping the state of the device tracker and feeding a switch node.

Looks like the trigger state node is running all the time regardless of whether the state has changed, is this correct?

thanks

Welcome to the forum @scottda

Are those Home Assistant nodes? If so you might be better off on an HA forum as not many here use it, preferring to use node-red for everything.

If not home assistant nodes you will have to give us some more clues as to which nodes you mean. Node red has a Trigger node built in, but not trigger state.

ok thanks Colin, it is indeed a HA integration so I shall take your advice and have a look over in those forums.

thanks for the speedy reply.
