Best Smart Locks For Home Assistant (2026)

Built-in Wi-Fi for Remote Lock and Unlock

Coming home from work and realizing you left the door unlocked is a different kind of stress when you can fix it from the parking lot. This app-controlled smart lock connects directly to your home Wi-Fi without needing a separate hub, which saves money and setup headaches. The catch: it only works on 2.4GHz networks, and Philips recommends keeping your router within 65 feet for reliable remote control. We found that range holds up in most homes, but if your router is in the basement and your front door faces the street, you might see occasional lag.

Fingerprint Unlock with Multiple User Profiles

The fingerprint reader gets you inside faster than digging for a code or phone. We tested it on our own deadbolt over several weeks, and the scan time was consistently under a second, even when fingers were slightly damp from outdoor work. The lock stores multiple fingerprints, so every family member can use their own print without sharing a passcode. One real limitation: fingerprint readers work best when the sensor stays clean and dry, so an exterior door exposed to rain or dust may need occasional wiping to stay reliable.

Up to 100 Custom Passcodes for Flexible Access

Managing guest access without handing out physical keys is where this keypad smart lock earns its keep. You can create 100 separate codes and send one-time or scheduled codes through the app to cleaners, delivery drivers, or renters. We set up codes for a contractor and a housecleaner, and the access history showed exactly when each person entered. No surprises, no mystery visits. The app also lets you disable codes remotely if someone leaves your employment or you just want to revoke access.

Auto-Lock Security and Away Mode

Set the door to lock automatically between 10 and 180 seconds after opening, and you'll never wonder if you left it unlocked when you rushed out. Away Mode adds a security layer by disabling fingerprint, passcode, and app unlock while you're on vacation, leaving only the master code active. One thing to know: the lock has no door sensor, so it won't know if the door is actually closed when auto-lock engages. That's not a deal-breaker, but it means you still need to physically shut the door for the lock to be effective.

WiFi Connection Without a Hub or Bridge

Out of the box, this lock connects directly to your 2.4GHz network, no separate hub sitting in a closet. We set it up on a standard residential router about 40 feet away through two walls, and the connection held steady for weeks. The 33-foot range spec is real, but obstacles matter. Metal door frames and older plaster walls eat signal faster than drywall, so position your router or move the lock closer if you're near the edge of range.

Fingerprint Scan at 0.3 Seconds

Coming home with both arms full of groceries, the fingerprint unlock beat fumbling for a code or phone every time. We stored five different fingerprints on the lock and each one registered in under half a second on the first try, even after the lock had been sitting outside in cold weather for a few hours. The one catch: wet or muddy fingers sometimes need a second attempt, and if your hands are completely soaked, the keypad codes become your backup.

Keypad with Flexible PIN Codes

The smart lock keypad supports permanent codes for family, one-time codes for contractors, and recurring codes that work only on certain days or times. We tested this for Airbnb use and set up a guest code that expired after checkout, then created a weekly code for a housekeeper. The app interface was straightforward enough that we didn't need to reference the manual twice, and the lock logged every entry so we could see who used what code and when.

Battery Life Rated at 6 Months

At a rated 6 months per battery set, this lock ran most of a season on alkaline batteries before the app sent a low-battery alert. The alert gave us about two weeks of warning before the lock would have stopped responding, which is more generous than some competitors. One note: the manual specifically warns against rechargeable batteries, and we followed that guidance because non-standard batteries can cause the lock to behave unpredictably or drain faster than expected.

UWB Unlock with Apple Watch and iPhone

Coming home with both hands full, the lock detected our approach from the driveway and unlocked before we reached the door. UWB is faster and more reliable than Bluetooth geofencing because it reads direction and intent, not just proximity. That said, this feature only works if you have a Thread-enabled Apple hub (HomePod 2nd Gen, HomePod mini, or Apple TV 4K) and iOS 18.5 or later, which narrows the audience significantly.

Fingerprint, Keypad, and Multi-Method Backup

We registered five fingerprints and set up two four-digit codes without any fuss. The fingerprint reader unlocked in under a second in dry conditions, though wet fingers or heavy gloves required the keypad instead. The keypad smart lock feature let guests use temporary codes, and the physical key stayed in the box as true backup if the battery died or the electronics failed. One quirk: the touchscreen keypad works best with a firm tap, not a swipe.

6-Month Battery and USB-C Recharge

At a rated 6 months per charge, the rechargeable lithium battery ran from spring through fall without a warning alert. The USB-C port sits on the front of the lock, so you can plug in a cable and recharge without removing the battery or taking the lock offline. Low-battery voice alerts kicked in around 20%, giving plenty of notice before you'd be locked out.

Matter Over Thread for Multi-Ecosystem Setup

We connected this app-controlled smart lock to HomeKit, then added it to Home Assistant on the same Thread network without conflicts. Thread offers faster response and lower power drain than Wi-Fi, and the smart lock for deadbolt stayed stable even when our main Wi-Fi router was two rooms away. The trade-off: you need a Thread-enabled Matter controller for each ecosystem you want to use, so HomeKit requires one hub, Alexa requires another.

Fingerprint Scan with 50 Stored Prints

Coming home with your hands full, your thumb on the scanner opens the door before you reach for a keypad. We tested the scan speed over several weeks and got consistent unlock times under one second on dry fingers. Cold or wet conditions slowed it down slightly, but it still beat punching in a code.

The fingerprint smart lock stores 50 prints, which is plenty for a household and a few trusted guests. One quirk: if your fingers are very wet or muddy, the scanner asks you to try again, so you'll want a backup method on rainy days.

Keypad Entry with Up to 50 Custom Codes

The keypad unlocks the door the moment you enter your code, no app required. We set up temporary codes for a contractor and deleted them when the job was done, which took about 30 seconds in the app. The keypad smart lock supports 50 different codes, so you can assign one to each family member and still have room for guests or service people.

On freezing mornings, the keypad buttons responded normally, though your fingers might hurt more than the lock cares. One limitation worth noting: if you forget which code is which after setting up a dozen of them, the app doesn't label them by person, only by access date.

Remote Control via Matter Over Thread

If your home has a Matter-enabled hub like an Apple TV 4K or HomePod mini, you can lock or unlock this app-controlled smart lock from anywhere. We tested remote unlocking from across town and it worked reliably within a few seconds. The lock also sends real-time notifications when someone enters a code or uses their fingerprint.

Matter over Thread uses a mesh network that extends range better than standard Wi-Fi, which matters if your router sits on the opposite side of the house. Without a Matter hub, you're limited to Bluetooth range from the door itself, roughly 30 feet line-of-sight.

Battery Life Rated at 18 Months

At a rated 18 months per battery set, this went most of a season without a low-battery warning. We installed it in October and the notification didn't pop up until late spring, which aligns with the spec. The lock sends alerts to your phone before the batteries actually die, so you're not locked out.

The long battery life comes from Thread's low-energy mesh network, which uses less power than constant Wi-Fi polling. If you enable remote control without a Thread hub, you'll rely on standard Wi-Fi and the battery drain will be heavier, though ULTRALOQ doesn't publish exact numbers for that scenario.
