A sensible add-on for SimpliSafe households, locking the door whenever the alarm arms and reporting every entry. It does nothing outside a current SimpliSafe system.

Overview
Arming the SimpliSafe alarm also locks the door with this smart lock, and disarming unlocks it again. A PIN pad comes in the box, the app shows each lock and unlock, and installation needs no drilling.
Tying the deadbolt to the alarm's arm and disarm routine removes the forgotten-lock problem. It only works inside a current SimpliSafe system, needs a single-cylinder deadbolt, and the key fob is sold separately.
Who it's for
SimpliSafe owners who want the front door to lock itself whenever the alarm arms will use it daily. Homes without a SimpliSafe system, or with a double-cylinder deadbolt, cannot use it.
Pros and cons
- Locks automatically when the alarm arms
- PIN pad included
- App alerts on every lock and unlock
- No drilling needed
- Works only with a SimpliSafe system
- Key fob sold separately
- Needs a single-cylinder deadbolt
- Battery life not listed
Performance notes
Locking follows the security system's state, so arming throws the bolt and disarming retracts it, with a timer as a backup. The lock stays connected to the SimpliSafe system and wireless network to report status. Repeated wrong PIN entries trigger a notification.
