【NEW】Open Sensor 2
Auto-lock when you need it — now smarter than ever 🎉
Locks automatically when the door closes 🔐✨
No more relying on timer-based auto-lock. With this new feature, your door locks instantly—just like a hotel.
New in this model: a button to temporarily disable auto-lock.
Perfect for quick trips like taking out the trash or checking the mailbox.
It also uses the same CR123A batteries as SESAME for added convenience 👍
Secure when you want it, off when you don’t—
making everyday life a little easier 🙆
Enhanced Software:
・Temporarily disable auto-lock when needed
・No reset required for updates or setting changes
・Detection range remains 22 mm, same as the previous model
・Powered by a single CR123A battery with over 5 years of expected life
・When using both 'Open Sensor Lock' and Sesame's built-in 'Timer Auto-Lock':
・If the door is open, the 'Timer Auto-Lock' is disabled and won't activate even after the set time.
・Once the door closes, the 'Open Sensor Lock' function takes over.
→If Sesame is unlocked without door movement, the Timer Auto-Lock remains active.
・Remote notifications: Receive notifications remotely when paired with Hub3.
・Matter compatibility: Can support Matter protocol when connected to Hub3.
・Sesame connectivity: 1 Open Sensor can be linked with up to 2 Sesame devices.
Compatibility Notice: While not currently compatible with original Sesame, SESAME mini/3/4, please use SESAME 5/5Pro for immediate enjoyment with SESAME. We are currently very busy, and although we plan to support older models in the future, specific timing is yet to be determined.
