Sunset/Sunrise:

You can set the events trigger to switch the event 'On' at 'Sunrise', 'Noon' and 'Sunset' by selecting the 'Sunset/Sunrise' option in the 'Select the trigger type' drop down menu.

Please note; Harmony knows whether it is Sunset, Noon or Sunrise by having the 'scheduler' in the 'Settings' menu set to your geographical location. The closest city/country can be selected in the drop down menu or the longitude and latitude values of your location can be entered in the boxes provided.

Click 'Next' when the trigger has been set to continue with the 'Event' setup.
