✓Editorial verdict
Which Should You Pick: Sifely or Aqara?
Pick Sifely if you want the lowest per-door hardware cost ($79.99) with five unlock methods and direct Auto Booking Code automation for Airbnb, Guesty, and Hostaway. Pick Aqara if you already run an Apple Home, Google Home, Alexa, SmartThings, or Home Assistant ecosystem and want locks plus sensors and automations sharing one Matter/Thread/Zigbee hub.

What each tool does well — and where it falls short
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.
What 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.
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.
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
Budget for the required hub and check compatibility for each device. The Hub M3 product page lists a one-time price of $159.99.
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.
Which Should You Pick
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.
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.
Where Sifely and Aqara actually differ
- Aqara’s listed US lock prices are $169.99 for U200, $189.99 for U100 and $269.99 for U400, each a one-time purchase. A separate Hub M3 costs $159.99.
- Sifely's Auto Booking Code natively integrates with Airbnb, Guesty, and Hostaway for auto-generated per-reservation passcodes; Aqara has no documented native PMS or Airbnb reservation integration — code rotation runs through Aqara Home or smart-home routines.
- Sifely offers five unlock methods (fingerprint, code, fob, smartphone, physical key); Aqara's U100 supports up to 50 fingerprint slots plus app/code, but fob unlock is not documented on Aqara's spec sheet.
- Aqara works natively across Apple HomeKit, Alexa, Google Home, SmartThings, Home Assistant, and IFTTT via Matter/Thread/Zigbee; Sifely has no documented smart-home ecosystem connectivity beyond its own app.
- Sifely has a reported ~10% touchpad failure rate and documented fingerprint read-but-fail issues; Aqara has no comparable touchpad-failure complaints surfaced but scored 3.9/5 on Knoji as of 2026-04-25, trailing some competitors, and publishes no comparable warranty terms.
Common objections
- Aqara has broad smart-home support across Apple Home, Google Home, Alexa, and Home Assistant — does Sifely's lack of ecosystem integration matter?
- For hosts building connected properties with voice control, automated scenes, or coordinated smart-home routines, Aqara's ecosystem breadth is a genuine differentiator Sifely cannot match. But most STR operators manage locks independently from broader smart-home systems — what they actually need is automated guest codes from their PMS. Sifely delivers that core workflow for Airbnb, Guesty, and Hostaway at less than half Aqara's hardware cost, which matters more than Matter support for most operators.
- Which billing limits and extra charges should I check for Aqara?
- Aqara’s listed US lock prices are $169.99 for U200, $189.99 for U100 and $269.99 for U400, each a one-time purchase. A separate Hub M3 costs $159.99.
- Sifely's touchpad and fingerprint reliability are flagged issues — is Aqara hardware more dependable?
- Sifely's ~10% touchpad failure rate and fingerprint read-but-fail issues are real concerns. Aqara hasn't surfaced equivalent specific complaints, but its 3.9/5 Knoji aggregate score trails competitors and it publishes no formal warranty terms. Sifely's failure mode is at the door with four other unlock methods (fingerprint, fob, smartphone, key) as fallback; Aqara's risk is more diffuse around hub dependency and the connectivity glue tying lock events to whatever code-rotation routine you've assembled. Neither is trouble-free.
