Configuration

Hi All

I need some help setting up lights ON/OFF every 30 minutes. This is what I have done but it is not triggering:

Steps are:
Trigger:
When Sun elevation is below 3.5 degrees
or when everybody leaves home for more than 5 minutes
or/and trigger Lounge Light every 30 minutes

Condition:
Everybody is away
Time is between 17:00 and 22:00

Action:
Delay: random time between 6 and 12 minutes
Toggle lounge light input boolean
Delay: random time between 6 and 12 minutes
Toggle lounge light input boolean

  alias: 2113 - Lounge Light ON/OFF @ Sunset when NO ONE is at Home or everyone leaves home
