Philips Hue Secure Smart Contact Sensor, Black - 1 Pack - Made for Indoor Doors and Windows - Requires Hue Bridge - Works with The Hue App

Excelent

Can’t say much other than, it works as intended. Set it up and forget about it.

I wanted to use this to turn on the lights in a room from a certain time to a certain time which is not possible in the Hue App. Had to integrate with HomeKit. Was not a huge issue but rather annoying. Also, most of the features for it you have to use with the Hue Security system rather than just a regular Hue device like the outdoor motion sensors.

I added this sensor to my bedroom closet to quietly notify me when my closet door is opened. It works perfectly. I was worried that it was refurbished, but it came perfectly packaged with mounting hardware and instructions on how to use it.

It is just a door sensor and works fine doing that. When grouped with other Philips Hue Secure products to form an alarm system, is where it fails. The only thing it does it put a notification on your phone when one of the devices is triggered. The alarm (flashing lights / siren) only comes on, if you go into the app and tell it to come on. Example: It is the middle of night and someone kicks you front door in, you get a notification on your phone and that is it. No flashing lights and no siren. Not a real alarm system.
