How to choose
Check the Alexa connection first
Three picks connect through built-in Wi-Fi, while the Sifely pairs with Alexa and Google Assistant through the optional Sifely WiFi Gateway, sold separately. If voice control matters on day one, a built-in Wi-Fi model avoids an extra purchase. Remote management follows the same split: the Sifely needs the gateway for remote management, while the other picks manage access through their apps over Wi-Fi.
Compare entry methods, not just voice
Fingerprint entry appears on the eufy, Sifely and Veise models, while the Philips uses physical buttons for passcode entry. Key fobs work with the Sifely, and IC cards work with the Veise. Match the entry methods to the people who will use the door: a keypad suits guests with a code, a fob suits someone without a phone, and a fingerprint suits a quick entry without codes.
Auto-lock timing and power
Auto-lock closes the door behind you: the Veise locks at 10s-180s and the Philips locks within 10-180 seconds through the app. Power differs too. The eufy runs on a 10,000mAh rechargeable battery. The Veise and Philips run on 8 AA batteries, with up to 240 days for the Veise and up to 6 months for the Philips. Check the battery type before buying, since a rechargeable battery and AA batteries need different spares.
