Yale Assure Lock 2

Quick verdict

Yale's modular design is the standout here. Buy the lock body once and swap radio modules as your smart home evolves. Wi-Fi or Z-Wave, your choice; the Matter module Yale announced in 2022 never reached its store, and Yale now sells Matter as a separate lock instead. It adds up in cost compared to a one-piece lock, but the flexibility is worth it if you're not locked into one ecosystem.

Standout: Swappable radio modules let you choose Wi-Fi or Z-Wave without replacing the lock.

Compatibility snapshot

Why it stands out

• modular design lets you add a Wi-Fi or Z-Wave Plus module to the Bluetooth lock body
• Z-Wave module gives fully local control through Z-Wave JS, and the Bluetooth radio works locally with Home Assistant's Yale Access Bluetooth integration
• sleek compact design compared to many smart locks

Reasons to hesitate

• module system means the base lock plus module adds up in cost
• no Matter option: the Matter module Yale announced at launch is not sold, so Matter buyers need the separate Yale Smart Lock with Matter
• Yale/August app experience can be inconsistent

Best for

• Z-Wave households that want a lock with fully local control
• buyers who want protocol flexibility via swappable modules

Avoid if

• you want the simplest single-purchase smart lock without module decisions
• you want Matter or Thread on this lock body

Privacy and local-control notes

The Z-Wave module and the Bluetooth radio both allow local control. Cloud features are optional, not required for core lock/unlock.

Home Assistant support: supported · integration path: Z-Wave JS with the Z-Wave Plus Smart Module (local), or Yale Access Bluetooth (yalexs_ble, official core integration, Local Push) on the Bluetooth and Wi-Fi versions; the Yale Access cloud integration is the fallback.
