Knoctify Light vibration mode does not support alarm clock function now. However, we are working on support this feature in the future with new product add-ons.

The user can either use double sided tape (for temporary mounting) or screws (for permanent mounting).  For screw mounting, the user will have to open up the casing, remove the circuit board and follow the drill guide holes on the casing to drill holes for mounting on the door or wall. The user can refer to the instruction manual for more information.

Yes. The user can select any combination of Light, Vibration and Sound. Refer to the user manual for instructions.

The Knoctify button uses a vibration sensor to detection vibrations on the surface that it is attached to. A special software is written to detect the vibration caused by knocking to trigger the button and activate the receiver light. Knock detection works best on a solid wooden surface and is not guaranteed to work on all surfaces. In some cases, when attached on the door, the button may be triggered by the opening and closing of the door as the movement of the door may be similar to a knock vibration.

Knock detection can be disabled to improve battery life. Refer to the user manual for instructions on how to disable knock detection.

Unfortunately, for the button, there is no low battery indication. The user will have to change the battery when the button stops triggering the light when pressed.

For the light, as the battery power gets weaker, the LED flashing will be less bright and this will be an indication that the battery needs to be replaced soon.

Up to 10 buttons can be linked to 1 light.

20 lights can be linked to 1 button.

Knoctify Button and Light is splash proof and should not be fully submerged in water. The Knoctify Button is designed for outdoor use and is waterpoof against heavy rain. Knoctify Light on the other hand is splashproof and can be used in the kitchen or bathroom.

The battery life for Knoctify as affected by various factors such as how often it is triggered and which mode is it in, and the type of battery used.

With knock detection feature enable, the Knoctify Button has an approximate battery life of up to 6 months (average 2 triggers a day). If knock detection feature is disabled, Knoctify Button will have a battery life of up to 1 year (average 2 triggers a day).

Knoctify Light has a battery life of up to 8 months with Light feedback enabled only (average 2 triggers a day).

The wireless range is about 150 m in a open space. Indoors, the wireless range can vary greatly because of difference obstacles that reduces the wireless range. Knoctify has been tested to work in doors with 3 walls inbetween up to a range to 50m which is more than sufficient for most houses.
