Keeps track of your door lock

Did I really lock the front door? The Homematic IP door lock sensor frees you once and for all from this nagging uncertainty, because the sensor detects at any time whether the door lock is locked or unlocked. Monitor your door in the Homematic IP app and check every opening and closing in the detailed event log.

Always know whether the door is locked

When you're out and about, check via the Homematic IP app whether your front door is locked.

And every time the door is locked or unlocked, it's recorded in the Homematic IP app’s event log. With the "secured locking" function, you can also see whether the door is open or closed in conjunction with a door and window contact.

Turns the key into a smart knob

Your key is transformed into a practical turning knob in no time with the door lock sensor.

The key simply turns with the door lock sensor. This means it’s still very easy to lock and unlock the door by hand.

Visual matching to your door fittings

Two caps in white and silver are included.

Provides more security

Just combine the sensor into your security solution.

When alarm mode is activated and when the door is unlocked

either Alarm mode is automatically deactivated or
an alarm is triggered.

Easy retrofitting

Simply insert your key into the door lock sensor and both together on the inside of the door into the lock - without drilling or screwing and completely invisible from the outside.

Thanks to its universal design, the device fits on all common key types for standard lock cylinders with emergency function. To lock or unlock the door from the inside, simply turn the door lock sensor in the corresponding direction like a knob.

Does my key also fit in the door lock sensor?

We've developed a template so that you can be sure that your key also fits into the smart door lock sensor. Simply print it out in its original size and place your key in the space provided.
