Best window and door detector

Open or closed?

Entry Sensor

Imagine always having a frient keeping an eye on doors and windows in your home. Someone who lets you know if you forgot to close a window. A frient who warns you if someone enters your home when you’re away. Someone who wants you to enjoy being away on vacation – and not worry about the safety of your home while you’re gone.

Now that’s a frient!

One step ahead of intruders

Placed on a door or a window, the Entry Sensor tracks when it's opened and closed. You'll have peace of mind, knowing that your home is safe - no matter if you're at home or away.

With this new frient, you'll be alerted immediately if someone is opening a window or door in your home – allowing you to act before the intruder does.

Just what I needed
I needed a Smartthings compatible door opening detector. Put the battery, pair it with the Smartthings app and working! Nice design, quality materials.
Good sensor
Good sensor, it takes standard AAA batteries so you can put rechargeable in it and easier to find of course. Connected with smartthings easily.
