eufy Security Smart Lock C30: What to Know
Per eufy's own official product page, the Smart Lock C30 has built-in Wi-Fi with no separate bridge required, and can be unlocked via the eufy Security app from anywhere, a physical key, voice commands through Alexa or Google Assistant, or a physical button on the lock itself. eufy states it supports up to 100 different passcodes, useful for households or short-term guests who each want a distinct code.
eufy's page lists an IPX3 waterproof rating and a stated operating range from -22°F to 158°F, plus a "wrong-try protection" feature that temporarily locks out further attempts after repeated incorrect passcode entries — a basic brute-force deterrent. Battery life is listed at roughly 5 months under a moderate-use estimate of 20-30 unlocks per day, and eufy states the lock is compatible with its own video doorbells and security cameras for a unified eufy Security app experience.
Worth flagging clearly: eufy's own page states this lock is not currently compatible with Apple HomeKit, IFTTT, or Matter, which sets it apart from the Schlage, Yale and (in Matter's case) other locks in this guide that emphasize broader smart-home standard support. If cross-platform compatibility beyond eufy's own ecosystem and Alexa/Google matters to you, weigh that against the lower price before buying.
