Alarms are the type of Trigger that let you activate a preset at a specific time of day. You can use this to help wake up, remind you when to pick up your kids at school, or dim the lights to signal it's time for Game of Thrones. To get started, just tap the + button in the Triggers tab and choose "Alarm". You'll be asked to choose a time of day, and can use a set of buttons to indicate which days of the week you'd like the alarm to go off. For your convenience, there are buttons to toggle on/off weekends, weekdays, or every day all at once.
Once you have everything set up, make sure you flip the switch to the ON position in your Triggers list.
One thing important to understand regarding both Timers (countdown) and Alarms (specific times) is how Lightbow presets work with your hardware. If you have Lightbow open when the trigger is supposed to go off, Lightbow will handle all the commands needed to run any type of animation you can create with the preset editor. If Lightbow isn't running at the time the trigger is supposed to fire, you will not see the full animation. For the Philips hue family of lights, your trigger information is stored on the bridge as soon as you flip the trigger's switch. The good news is that even if your Apple devices are powered off later, your Philips bridge will take care of it. The bad news is that the bridge can only store static colors, so you won't get any animated loops. LIFX and WeMo users are out of luck as well—at this time, there's no way for Lightbow to store trigger information on that hardware, so you'll need Lightbow running for your trigger to fire at all. Stay tuned though, we're working on a possible solution, depending on what the companies will allow with their hardware.
