I ran into a problem with the ISY sending an email notice at power-up because my network router was not up and running yet. Simple fix was for the ISY to wait 5 minutes and then send the power-up notice.
power_up_notify program:
If
- No Conditions - (To add one, press 'Schedule' or 'Condition')
Then
Wait 5 minutes
Send Notification to All
Else
- No Actions - (To add one, press 'Action')
