Best Smart Locks for Home Assistant, SmartThings & Hubitat (2024)

Choosing the right smart lock for your home automation setup isn’t just about security—it’s about seamless integration with your hub, reliable local control, and a protocol stack that plays nicely with your existing ecosystem. Whether you’re running Home Assistant with Zigbee2MQTT, SmartThings with a mix of protocols, or Hubitat for purely local control, the lock you choose will become one of your most-used automation triggers.

We’ve analyzed community sentiment across Reddit, Amazon reviews, and YouTube to rank the best smart locks for enthusiasts who demand more than just app control. These rankings reflect real-world experiences from users who’ve battled range issues, firmware bugs, and integration headaches—so you don’t have to.

Quick Compare

1. Aqara Smart Lock U100 – Best for Zigbee Ecosystems

Score: 78.6/100 | Amazon (Aqara Smart Lock U100)

The Aqara U100 takes the top spot with the highest community sentiment score, and for good reason. This is the lock that Zigbee enthusiasts have been waiting for—native Zigbee 3.0 support means rock-solid local control through Home Assistant’s ZHA or Zigbee2MQTT, plus seamless integration with SmartThings. At $189.99, it undercuts premium WiFi locks while delivering better protocol support for serious home automation.

Key Strengths

Zigbee 3.0 Native Integration: Unlike WiFi locks that require cloud polling or proprietary hubs, the U100 communicates directly with your Zigbee coordinator. This means sub-second status updates in Home Assistant and reliable automations that don’t depend on internet connectivity. Reddit users consistently praise the instant lock state changes in their dashboards.

Apple Home Key Support: When paired with an Aqara hub, the U100 supports Apple Home Key—the NFC-based unlock feature that turns your iPhone or Apple Watch into a physical key. This is a premium feature usually reserved for $300+ locks like the Schlage Encode Plus.

Multi-Protocol Flexibility: Bluetooth fallback means you can still unlock via the Aqara app even if your Zigbee network goes down. For Home Assistant users running Bluetooth proxies with ESP32 devices, you get redundant control paths.

Strong Battery Life: Users report 6-8 months on four AA batteries with typical use, better than most WiFi locks that drain batteries maintaining constant connections.

Key Weaknesses

Aqara Ecosystem Lock-in: While Zigbee integration works great, some advanced features like Apple Home Key require an Aqara hub (M2 or M3). This adds $60-120 to your total cost if you’re not already invested in Aqara devices.

Regional Availability: The U100 is easier to find in European and Asian markets. US buyers sometimes face longer shipping times or limited stock.

Fingerprint Reader Sold Separately: Unlike locks with a built-in fingerprint reader, the base U100 doesn’t include fingerprint unlock—you’ll need the U100 Pro model or separate fingerprint module.

Why It Ranks #1: The U100 wins on protocol choice. For Home Assistant and Hubitat users who’ve built their systems around Zigbee (avoiding cloud dependencies), this lock delivers exactly what they want: fast local control, excellent battery life, and a price point that doesn’t require justification to a spouse. Reddit’s r/homeassistant community consistently recommends it as the “just works” option for Zigbee networks.

2. Schlage Encode Plus Smart WiFi Deadbolt – Premium Lock with Apple Home Key

Score: 65.7/100 | Amazon (Schlage Encode Plus Smart WiFi Deadbolt) | Schlage Store

The Schlage Encode Plus represents the premium tier of smart locks, commanding $299.99 for the Schlage name, ANSI Grade 1 security rating, and Apple Home Key support. It’s the lock recommended when security professionals and locksmiths weigh in on Reddit threads. However, the 65.7/100 score reveals a tension between build quality and user experience.

Key Strengths

Apple Home Key: Tap your iPhone or Apple Watch to unlock—no app opening, no code entry. This works via NFC and uses the same secure element that stores your credit cards. For Apple ecosystem users, it’s transformative. The lock unlocks as you approach, then automatically relocks when you walk away.

ANSI Grade 1 Security: The highest residential security rating. The Encode Plus has a hardened steel bolt, anti-pick shield, and meets commercial building security standards. If you live in an area where break-ins are a concern, Schlage’s reputation matters.

Built-in WiFi: No bridge or hub required for remote access. The lock connects directly to your 2.4GHz network and integrates with SmartThings, Apple Home, and (with some configuration) Home Assistant via the Schlage cloud API.

5-Year Electronics Warranty: Schlage backs the electronics for 5 years, double the industry standard. The mechanical lock has a lifetime warranty.

Key Weaknesses

Price: At $300, it’s 50% more than the Aqara U100 and you’re paying a premium for Apple Home Key and the Schlage name. Android users get minimal benefit from the higher cost.

Battery Life: WiFi kills batteries faster. Users report 3-4 months on four AA batteries, half the lifespan of Zigbee alternatives. Some Home Assistant users have set up automations to disable WiFi when home and enable it remotely, but this feels like a workaround.

Cloud Dependency: Like most WiFi locks, the Encode Plus requires Schlage’s cloud for remote features. The lock itself works offline, but status updates and remote unlocking require internet connectivity and Schlage’s servers.

State Sync Issues: Community reports of the lock state desynchronizing from Home Assistant or SmartThings are concerning. Manual lock/unlock doesn’t always trigger status updates, leading to automations based on incorrect states.

Community Testimonials

Community concerns:

“Sometimes I have my lock entity in HA desync from the actual state, like when turning it manually. Have you encountered this? I have an august gen 3 t…”
— Dead_Politician on r/homeassistant

Why It Ranks #2: The Encode Plus scores lower than expected because enthusiast communities value local control and protocol choice over brand names. While the lock itself is excellent, the cloud dependency and state sync issues frustrate Home Assistant users who’ve built systems specifically to avoid these problems. The high price compounds the disappointment when automations fail because the lock didn’t report its state change. For Apple users willing to pay for premium hardware, it’s still a top choice—but the community has spoken: Zigbee integration matters more than Apple Home Key for most enthusiasts.

Newly Added: Yale Assure Lock 2 (Wi-Fi)

Protocol: Wi-Fi, Bluetooth
Buy on Amazon

Not yet rated. We haven’t collected community sentiment data for this lock, so it has no score and isn’t ranked against the others. What follows comes from Yale’s own product information, not from user reports.

The Assure Lock 2 line has Wi-Fi and Bluetooth versions in keypad and touchscreen styles, with keyed and key-free options. All are set up in the Yale Access app and work with Apple HomeKit out of the box. The Wi-Fi module is built in and needs a 2.4 GHz network, so no separate bridge is required. Controlling the lock through Apple Home while you’re away needs a HomePod or Apple TV as a home hub. Yale lists Auto-Unlock, and Auto-Lock with DoorSense, as features.

Apple Home Key is not part of this model; Yale sells it on a separate Assure Lock 2 Plus. Check the exact keypad or touchscreen variant on the Amazon listing before you buy, since several are sold under this name.

Yale|August Wi-Fi Smart Lock with Keypad

Protocol: Wi-Fi, Bluetooth
Buy on Amazon

This is the black model AUG-SL05-K04-G01. It installs on the inside of the door over your existing deadbolt, so you keep your key. Wi-Fi is built in with no separate bridge, and it works with Alexa, Apple Home and Google Assistant through the Yale Access app. The Yale Keypad can be mounted anywhere within Bluetooth range. Auto-Lock with DoorSense locks the door after it closes. Listings say it works in the US and Canada only. This SKU is the keypad version without a fingerprint reader; separate “Keypad Touch” listings are a different product. The Amazon listing was seen to be sold by a third-party seller rather than Amazon or Yale.

SwitchBot Lock Ultra with Keypad

Protocol: Wi-Fi, Bluetooth
Buy on Amazon

Amazon titles this listing “Smart Lock Ultra with Keypad, Fingerprint Door Lock … Built-in WiFi Keypad Deadbolt”, sold by SwitchBot. SwitchBot’s own pages say the Lock Ultra is a retrofit lock with 3 rechargeable 18350 cells (about 9 months at 10 operations a day), 0.3-second unlocking and up to 17 unlock methods when paired with a keypad and Hub Mini. The base lock has no fingerprint reader of its own; fingerprint comes from the paired keypad. Matter support is limited to lock and unlock and needs a SwitchBot Hub as a bridge. We could not confirm from the listing which keypad is bundled or how Wi-Fi is provided, so check the Amazon listing contents before buying.
