Onvis-enabled door sensor for HomeKit security

Onvis recently updated their door/window contact sensor, the CT3, to incorporate Thread technology. With this update, the Onvis CT3 contact sensor is now able to seamlessly integrate with HomeKit Over Thread for a more reliable experience through Siri and the home app. This contact sensor is designed to keep you aware of when doors and windows open and close as well as trigger automations.

Weekly HomeKit is a series focused on smart home accessories, automation tips and tricks, and everything related to Apple’s smart home framework.

Why do you need a HomeKit door sensor?

While you may already have an alarm system in place, these sensors can be extremely useful for unlocking automations when doors or windows are opened. Especially if your current security alarm doesn’t support HomeKit, these devices can be a powerful addition.

For example, you can create a HomeKit automation to turn on your living room lights when the front door is opened after 7 p.m. light switch. You can also set it to turn on the lights in your master bedroom if a window is opened after a certain amount of time, etc. Think of the number of teen movies where people sneak in and out of houses to deal with problems that could have been avoided with devices like this!

Installing the Onvis CT3 Door/Window Sensor is a breeze and can be done in a few simple steps. Here’s how:

  • Remove the sensor box: Start by unpacking the Onvis CT3 Door/Window Sensor.
