Finally a better alternative to Nuki and Linus. The Simpled motorised TTLock can be easily retrofitted to most doors that use a euro profile cylinder. The lock is supplied with a custom keyed euro cylinder and can be fitted in under 15 minutes. It works using the built in motor to turn the deadbolt. It uses 2 x 18650 batteries (not included). and under normal use should last at least 6 months. 

The lock can be unlocked via the free TTLock smartphone app. Want to use a PIN code? then we offer several wireless BLE keypads that enable this. Need to control remotely then add a G2 Wi-Fi gateway. Includes a magnet for the door frame so the lock will autolock when closed. Backplate of the lock fixes directly to the door making it very secure.  Suitable for interior and exterior doors. No Wi-Fi bridge or batteries included. Full spec below. 

This lock can be integrated with Airbnb and 100 + other integrations via RemoteLock software
