Works with Matter
Works with Apple Home, Google Home, Alexa, SmartThings or Home Assistant (you need one of their Matter hubs, such as a HomePod mini or Nest Hub). It does not connect to the Locksure Display Hub system. If your Locksure came with a Display Hub, you need the Thumb Turn Additional Monitor Pack instead.
The Matter Thumb Turn sensor sits over your existing thumb-turn lock and reports real lock state to the Matter controller you already use: Apple Home, Google Home, Amazon Alexa, SmartThings or Home Assistant. No cylinder swap, no Locksure Hub required. Want door open/close on the same Matter tile? Add the optional Open/Close Magnet accessory for £9.99.

Matter Thumb Turn Sensor, Technical Specifications
- Fits over the profile of an exposed barrel (must be at least 1mm exposed)
- Single device monitors locking and unlocking from both sides of the door
- Open/Close Magnet sold separately (£9.99), adds door open/close detection to the same Matter device as a second endpoint (Contact Sensor)
- Matter native, pairs with Apple Home, Google Home, Amazon Alexa, SmartThings and Home Assistant
- No extra hub needed if you already have a Matter controller
- Thread mesh, extends through walls via any Thread border router (HomePod, Apple TV, Nest Hub, Echo 4th gen, SmartThings, Eero 6+, SkyConnect)
- ~18 months battery life on a CR2032 coin cell at the lowest TX power setting (Thread sleepy end-device, ICD)
- Signed OTA firmware updates over Thread, straight from the app
Pairing & Compatibility
You need a Matter controller and at least one Thread border router on your network. Common border routers include HomePod mini, Apple TV 4K (Wi-Fi + Ethernet, 2021 on), Google Nest Hub (2nd gen), Amazon Echo (4th gen), SmartThings Hub v3+, Amazon Eero 6+, and the HA SkyConnect dongle.
Heads-up on battery reading: the battery percentage is estimated from coin cell voltage, which stays almost flat for most of a CR2032’s life, so the gauge reads conservatively at the top end. A brand new cell typically shows 80 to 95% rather than 100%. This does not affect battery life. Watch the trend rather than the exact number, and replace the cell when the reading starts falling steadily. A gauge refinement is planned in a future free OTA.
Customer Reviews
“The visual flash of the LEDs alone when I lock the door really stick in my memory. Locksure has been on my door for over six months now and I want to keep it!”
, Jason, Stevenage ★★★★★
“We have a three story house and, just before bed, I get paranoid if I remembered to lock the door. No more with Locksure, I just check the app and have peace of mind.”
