Boost is essentially a countdown timer. You can specify how long you would like before the device turns ON/OFF. Like Timers, Boost can also be applied to Groups.
EXAMPLES OF USE:
Your WIFIPLUG GLASS+ is controlling your kitchen ceiling lights and they are currently switches ON. You're leaving the House and it's dark outside so you set a Boost for 30 minutes just before you leave. In 30 minutes time, your kitchen ceiling lights will turn OFF creating the illusion that somebody is still in the House.
Your WIFIPLUG POWER's are controlling your kids' T.V.'s, they are currently switched ON and you have them linked together in a Group. It's nearly bedtime so you set a Group Boost for 15 minutes. The T.V.'s will then switch OFF after a 15 minute period.
