Can I do a delay?

Can I configure it so there is one press of the button that sends a signal to the gate then a 25 second delay and it automatically sends a second activation of the relay?

Is there nothing for me to configure if I do IO line passing?
Sorry. New to this

You would need to use a sample rate and to hold that line in that state for that to work.

Oh and yes, you do need to configure this to work. http://knowledge.digi.com/articles/Knowledge_Base_Article/XBee-802-15-4-Digital-Input-Output-Line-Passing/?q=DIO+line+passing&l=en_US&fs=Search&pn=1
