Try SifelyWhat Aqara does well
Strong cross-ecosystem compatibility via Matter, Thread, and Zigbee
Aqara hubs and locks plug into all four major US smart-home ecosystems plus Home Assistant. The Amazon listing for the Hub M3 lists support for Apple HomeKit, Alexa, SmartThings, Home Assistant, and IFTTT.
One-time hardware cost, no subscription required
Unlike RemoteLock or igloohome's cloud tiers, Aqara devices work locally through a hub with no mandatory monthly cloud fee for owner use, which compounds well over years of ownership.
Purpose-built guest-access features in lock firmware
Aqara locks support one-time and time-bound passcodes plus up to 50 fingerprints managed remotely from the Aqara Home app, fitting short-stay turnover without a PMS round-trip.
What Sifely does well
Auto Booking Code pulls reservation data and generates time-limited passcodes automatically
The feature integrates with Airbnb, Guesty, Hostaway, and other platforms to create guest codes without manual entry — a meaningful time-saver at 5+ properties.
Five unlock methods give guests multiple fallback options
Fingerprint, code, fob, smartphone, and physical key mean a single failure mode rarely locks a guest out entirely. The reversible handle simplifies installation on any door.
Configurable auto-lock prevents the common STR problem of unsecured doors
The lock re-engages after a set delay, removing reliance on guests remembering to lock up — a frequent pain point flagged in STR operator forums.
Where Aqara falls short
No native PMS integration
Aqara has no documented native integration with Hostaway, Guesty, Lodgify, OwnerRez, or Hospitable. Hosts must rotate codes manually, use Apple/Google automations, or layer third-party lock middleware.
Hub-dependent for full functionality
Most Aqara devices are Zigbee 3.0 and require an Aqara hub for remote control, adding a $129.99+ per-property capex line and a single point of failure that owners of one-bedroom condos may find heavy-handed.
Mixed user reviews vs. competitors
On consumer aggregator Knoji on 2026-04-25, Aqara scored 3.9/5 versus Eufy's 4.7/5. Operators should weigh that gap against Aqara's lower price point.
Where Sifely falls short
Touchpad responsiveness is inconsistent, working roughly 90% of the time
User reviews report intermittent touchpad failures. For high-turnover STRs where every check-in matters, a 10% failure rate creates real guest friction and support burden.
Remote management requires purchasing a separate WiFi gateway
The base lock is Bluetooth-only. Remote code management — the core value for multi-property hosts — is locked behind an additional hardware purchase at undisclosed pricing.
Fingerprint scanner reliability is a recurring user complaint
Reports describe the scanner reading correctly (green light) but failing to unlock. For hosts relying on biometric access as the primary unlock method, this undermines the convenience promise.
Pick Aqara if
Hands-on hosts of 1–10 doors who already run an Apple Home, Google Home, Alexa, or SmartThings ecosystem and want affordable Matter/Zigbee locks that issue one-time guest codes.
Skip Aqara if
You manage 30+ doors and need turnkey, audit-logged, PMS-synced lock automation — look at RemoteLock or August/Yale paired with Operto instead.
Pick Sifely if
STR hosts managing multiple properties who need automated passcode generation tied to booking platforms like Airbnb, Guesty, or Hostaway — and want to avoid monthly lock software fees.
Skip Sifely if
You need guaranteed 24/7 hardware reliability for high-turnover properties, require integrations with PMS platforms beyond the currently supported list, or need enterprise-grade remote fleet management.
