Smart Lock Alexa Google Home Integration Guide¶

Guide to integrating smart locks with Amazon Alexa and Google Home for UK homes covering voice control, routines, Alexa Guard Plus, and troubleshooting smart home integration.

Voice Assistant Integration with Smart Locks¶

Smart locks integrate with Alexa and Google Home for voice control. Alexa capabilities: check lock status, lock by voice, include in routines. For security, Alexa cannot unlock by voice alone - must confirm on Echo Show or use PIN. Google Home: similar features plus voice unlock with voice match verification. Compatible UK locks: Yale (Alexa + Google), Ultion (Alexa + Google), Nuki (Alexa + Google). Integration requires a bridge/hub connected to WiFi. Alexa Guard Plus (£5/month or £49/year) adds automatic lock when you say Im leaving.

Setting Up Voice and Routine Integration¶

Alexa setup: Open Alexa app > Skills & Games > find your lock skill (Yale Home, Nuki, Ultion) > Enable and link account > Discover devices. Create routines: Alexa app > Routines > Add. Trigger: Voice (Alexa, Im leaving). Actions: Lock front door, Turn off lights, Arm alarm. Google setup: Open Google Home app > Add > Set up device > Works with Google > find your lock > link > assign to room. Create routines in Google Home. Both platforms offer scheduling (auto-lock every night at 10pm). For multi-assistant households, most locks support both platforms, so you can set up both.

FAQ¶

Can I unlock my door with Alexa?: Yes but requires PIN confirmation on Echo Show screens. Google supports voice unlock with voice match verification.
What happens if the internet goes down?: Voice control and routines require internet. The lock still operates locally via keypad and physical key.
Can I integrate locks with other smart home devices?: Yes - routines combine locks with lights, cameras, alarms, and thermostats for comprehensive automation. For more information see our Smart Lock Auto-Lock and Geofencing Guide.
