Hama WiFi door and window contact

Windows, doors, patio doors or garage doors often provide easy entry points for a burglar. If you do not want to convert your flat, house or property into a loathsome high-security wing, our door and window contact gives you uncomplicated added security without building-related downsides. If windows and doors are opened when nobody is at home, you will receive an alarm notification on your smartphone, enabling you to take rapid action.

WiFi door and window sensors as a warning system

The current state of windows and doors is displayed on your smartphone by the WiFi sensor using the Hama Smart Home app. If there is a change to this state, you will receive an alarm push notification. The door and window contact, therefore, not only gives you timely information about a possible break-in; the state report also alerts you, for example, if the patio door was inadvertently closed by the cleaning lady so that the dog can no longer go outside while you are out shopping; or if the house sitters have accidentally left a window open while you’re on holiday. You can then sort out these problems by making a simple call. Similarly, you will receive an alarm message if someone tampers with the closed window, or with the door and window sensor itself. You can then notify the police or neighbours in no time at all, and scare away or ideally catch the burglar.

For a more forceful deterrent, you can link the door and window sensor to an alarm siren which is connected using our WiFi socket, for example. In this case, you should note the following: If house sitters, children or dog walkers will be coming into the house and will need to open windows and doors fitted with the contact, you should first disable it for the duration of their presence.

Simply ask Amazon Alexa or Google Assistant

Of course, the WiFi contacts can also be connected to Amazon Alexa and Google Assistant. You can then simply use a voice command to query the state of all doors and windows fitted with our door and window security devices. The status query works with the following voice command: ‘Alexa/OK Google, is my window/door open/closed?’

Simple installation without a hub

Many smart home products require an additional gateway that functions as a transmitter between the wireless network and device. Without this gateway (also bridge or hub), a connection cannot be established between the smartphone/tablet and smart device (smartphone/tablet – WiFi – gateway/bridge – smart device). Here, Hama has a clever and practical solution: The WiFi door and window contact can be installed without a gateway and integrated directly into your wireless network – this simplifies installation and saves additional costs. The WiFi contact consists of two parts – a sensor and the device itself. For the sensor to respond reliably, you should fit it directly to the window or door frame, and the second part directly to the window. Both must be in line. Drill-free mounting is possible thanks to the adhesive pad. If you prefer to rely on the secure hold of screws, the door and window contact can be screwed on. Once the contact has been mounted, you insert the batteries: The installation now continues step by step.

Quick and easy setup

All you need to set up the WiFi door and window contact is the Hama Smart Home app, which you can download onto your smartphone or tablet for free from the Google Play Store or Apple App Store. The app makes it easy to connect Hama Smart Home products to your home WiFi network. No expensive additional gateway or hub is required; it simply works with any wireless router.

Test results


Price/Performance: outstanding

"Hama has made a good decision by making their smart home system usable without a hub and using WLAN as the control protocol. For beginners - who really only use a few smart devices or want to slowly get to grips with the topic - a great option. These models are a great example of this. In any case, full points are also awarded for the app. It is clear, intuitive and leaves nothing to be desired. Above all, the fact that there are small sub-apps for each product and that you can combine the functions in many ways through scenes and automations is a delight. I am also convinced of the quality of the individual components. Hama offers really great products at the usual low price that are more than worth a look. It's hard to find a simpler and cheaper way to start your own smart home. So: grab it, test it, enjoy it."
