Nordic-powered Matter-over-Thread smart lock enables remote lock and unlocking for intelligent home security
eufy’s E30 Smart Lock employs the Matter-over-Thread connectivity of Nordic’s nRF52840 SoC, enabling integration with multiple smart home ecosystems
eufy has launched a Matter-over-Thread compatible smart lock that delivers intelligent home security while also allowing it to be integrated into a wide range of smart home ecosystems. The ‘eufy Smart Lock E30’ employs Nordic Semiconductor’s nRF52840 SoC to power the Matter-over-Thread connectivity, enabling users to lock and unlock their smart lock via any Matter-compatible ecosystem hub device integrating a Thread border router. The smart lock also provides built-in Wi-Fi connectivity.
Once installed and connected to Matter-compatible solutions using the nRF52840 SoC, the eufy Smart Lock E30 can be remotely locked and unlocked via the relevant smartphone app and/or smart home solution – for example, a smart speaker or voice assistant device. Users can also monitor and control the lock’s status when away from home, and authorize temporary unlock passwords for trusted visitors. Additionally, the E30 provides additional unlocking methods, including fingerprint recognition, password entry, and a traditional key.
This impressive battery life is made possible, in part, by the ultra-low power operation of the Nordic nRF52840 SoC.
Seamless integration
By integrating with platforms supporting Matter, like Apple Home, SmartThings, Google Home, and Alexa, the lock can interact with all major smart home devices, supporting features like automatically turning lights on when the door opens and off when it closes.
The nRF52840 is built around an Arm® Cortex™-M4 MCU with floating point unit (FPU) running at 64 MHz, and incorporates an Arm CryptoCell-310 cryptographic accelerator delivering an extensive range of efficient cryptographic options for applications demanding the highest level of security, such as smart home applications. It also integrates Arm TrustZone® providing trusted execution by implementing a division between secure and non-secure non-volatile memory (NVM), RAM, peripherals, and GPIOs.
The smart lock is powered by eight AA batteries, providing a lifespan of up to eight months before battery replacement during standard operation (10 locks/unlocks per day). This impressive battery life is made possible, in part, by the ultra-low power operation of the Nordic nRF52840 SoC. Designed with efficiency in mind, the nRF52840 features a fully-automatic power management system that optimizes energy usage, significantly reducing power consumption.
