The SwitchBot Lock Ultra Touch Combo is a smart home device designed to upgrade existing door locks without the need for replacing them entirely. This retrofit lock allows users to unlock doors using various methods, such as a numeric code, fingerprint, or even voice commands. The system includes a motorized locking mechanism, a touchscreen keypad with a built-in fingerprint reader and NFC support, and a mini hub that connects to WiFi and integrates with other smart home devices. The combo package is currently available at a discounted price of 179.99 euros for Amazon Prime members, down from its usual price of 249.99 euros. One of the key selling points of this lock is that it can be installed without drilling into the door or replacing the existing cylinder, making it a user-friendly option for those who want to upgrade their security without professional help. It also comes with an accessory kit to ensure compatibility with different door configurations and supports up to 15 different unlocking methods, including app control, Apple Watch, and a rotary button. The lock features a rechargeable USB-C battery that can last between 9 to 12 months with typical use—around 10 lockings or unlockings per day. The Keypad Touch component is also waterproof, with an IP65 certification, and runs on its own batteries, ensuring durability in various weather conditions. The included mini hub allows for remote control via 2.4 GHz WiFi and can integrate with several popular smart home platforms, such as Apple Home, Alexa, Google Assistant, SmartThings, and others. The SwitchBot Lock Ultra Touch Combo includes six security features designed to enhance user safety. These include automatic magnetic locking, a detailed history log in the app, two-step verification for remote unlocking, and an alarm that triggers after multiple failed attempts at the keypad. The system is compatible with existing Matter ecosystems, which are designed to allow different smart home devices from various manufacturers to work together seamlessly. This compatibility, along with its straightforward installation process, makes it a versatile and accessible option for homeowners looking to upgrade their home security.
