This makes it a practical option for homeowners, rental hosts, and property managers who want several ways to provide access.
Its Bluetooth connection allows users to manage access and monitor activity locally through the companion app. For users who need remote management or voice control, an optional Wi-Fi gateway adds compatibility with Amazon Alexa and Google Assistant.
The Dermum S1 also includes practical security features such as auto-locking, anti-peeping password protection, privacy functionality, and an anti-theft alarm.
