Your Tesla detects something. You get alerted. The moment Sentry Mode reports an event, SentryAlert alerts you on your iPhone, even when the app is closed. To keep watch, SentryAlert never wakes your Tesla: it uses the events your car already sends. What SentryAlert does • Sentry Mode alerts A real-time notification as soon as your Tesla reports a Sentry Mode event, from a detected threat to a triggered alarm, even when your iPhone is locked. • Riposte In case of a threat, respond right from your iPhone: Riposte sounds the horn, then flashes the headlights. The alert notification opens the vehicle with Riposte ready; hold the button for two seconds to send it. • Automatic headlight flash Off by default. Turn it on for a vehicle and SentryAlert can automatically flash the headlights on a threat or an alarm. Riposte and automatic flash use the Tesla "Vehicle commands" permission. Receiving alerts doesn't require it. • Event history Your alerts stay available in the activity feed. • Several vehicles Watch one or more Teslas from the same account. • Easy on your battery No wake-up command to keep watch: events arrive when your car is already awake, so the battery impact is negligible. What you need A Tesla account connected to SentryAlert and Sentry Mode turned on in your vehicle. Your Tesla connection You sign in through Tesla's official sign-in page, so your Tesla password is never entered in SentryAlert. You can delete your account and its data from the app. Available in 16 languages. Plans Solo (1 Tesla), Duo (2) or Garage (up to 5): the same features, based on how many Teslas you have. • Flexible: month to month, no commitment. • 12 months: pay upfront and save, or pay in 12 monthly payments on Solo, where this option is available. • Lifetime: Solo or Duo, a single payment, no subscription, no renewal. 7-day free trial on subscriptions for eligible accounts. Applicable prices and terms are shown in the app before you buy. SentryAlert is an independent application and is not affiliated with Tesla, Inc.
