The Best Z-Wave Door and Window Sensors

When you think of the best Z-Wave door sensors, you think of security systems. Monitoring the security status of a door is one use of a door sensors, but there are endless additional uses when paired with a home automation controller.

For example, Z-Wave door sensors can trigger lights to turn on when doors are opened, notify you if someone opens the liquor cabinet, or remind you if a door is left open more than five minutes.

You will discover dozens of uses for door and window sensors in your smart home. This article will make sure you find the best z wave door sensor for your home.

The Best Z Wave Door Sensors

The table of products below doesn’t contain every Z-Wave door sensor on the market (there are dozens). But it does include products that I consider reliable and useful depending on your needs.

The article below explains features to look for and detailed information for each of these door sensors.

What is a Z Wave Door Sensor?

A door sensor is a contact sensor that typically consists of two parts. The first part is the main body that contains the battery and communication components. The second part is a smaller piece containing a magnet. When the second piece (the magnet) is close to the first piece (the body) then the sensor registers as closed. When the two pieces are separated, then the sensor sends a signal that the door is open. Almost all sensors work by using this simple concept.

Z-Wave and Z-Wave Plus is one of the primary communication protocols used in home automation. It has been around for more than ten years and is known for being extremely reliable. Z-Wave technology uses banking level encryption to ensure your devices are secure. Z-Wave is also a mesh network, which means the more devices you have in your home, the stronger and more reliable you network.

Smart Hub Required
Z-Wave door sensors require a smart home hub such as Samsung SmartThings, Vera, or HomeSeer. I use the SmartThings hub in my home and recommend it for your home too.

What should I look for in a Z Wave Door Sensor?

A door, window or contact sensor provides important information or triggers important actions in your home. As a result, the most important quality you are looking for is reliability. Size and aesthetics are also important, but it is worthless to have a nice looking sensor if it doesn’t work consistently.

Features to consider in a Z Wave Door Sensor:

  • Sensitivity – This refers to the amount of gap that you can have between the two components and still correctly report an open or closed status.
  • Technology – This article focuses on Z-Wave devices, but look for Z-Wave Plus certification. Z-Wave Plus door sensors offer the newest technology, but are backwards compatible will all Z-Wave devices. Z-Wave plus is 50% better on battery life, 67% better with range, 250% higher in bandwidth and offers other features that make the device easier to use and more reliable.
  • Battery Life – You don’t want to change batteries every few months in your sensors. Look for battery life of at least one year and preferably more than two years.
  • Style and Size – The door and window sensors come in many different sizes and styles. If you want a device that is hidden then you should consider one of the following:
    • 1.  Recessed Door Sensor – Devices recessed inside the door and hidden from view.
    • 2.  Ultra Thin Door Sensor – Devices that are thin enough to mount on the top or side of the door.
  • Color – Most devices come in a standard white color, but some brands include other options such as brown. If you really want to match the color of your door, then consider a sensor that is paintable.

Ecolink Z-Wave Plus Door and Window Sensor

The Ecolink Z Wave door sensor is a great choice for adding sensors to all the exterior doors in your home. It is one of the best performers with a battery life of up to 3 years and magnets that can reliability trigger with a gap as big as ⅝ inch. The sensor also reports tampering if the outer cover is removed.

The Ecolink door sensor can also work with hard wired sensors. For example, if you have a group of windows with hard wired sensors, you can connect the hard wired sensor with the Ecolink Z-Wave sensor. After it is set up, the Z-Wave sensor will signal a window is open if any of the hard wired sensors are triggered. This is a great option is you already have hard wired contact sensors from your alarm.

The Ecolink Z Wave door sensor is one of the largest options (3.35 x 1 x 1 inches), but I find that it isn’t noticeable once placed on the door. The device includes white and brown covers so it blends in better with the color of your door.The Ecolink Z Wave door sensor is the device I personally use the most and highly recommend. I have several of these throughout my home including the standard Z-Wave sensors. Over the past four years, I have only had issues with one of these sensors and that just start started a couple of weeks ago. I will replace this sensor with the newer Ecolink Z Wave Plus door sensor.

Aeotec Door / Window Sensor 7

The Aeotec door and window sensor is one of the newest sensors on the market. Batteries last up to 3 years with light use before they need changed, and it uses 1 1/2 AA battery. The battery life is based on 5 opens per day so you will have to adjust the life up or down based on your location and usage. The sensor is one of the smallest on the market, which is impressive with all the sensors. This device includes the contact sensor, a low voltage / dry contact sensor, and a “tilt” sensor. The device also has tamper detection to report if the cover is removed. The “tilt” sensor isn’t a traditional tilt sensor and utilizes the external magnet. Overall, Aeotec makes a lot of good products, but the reported quality and reliability make me hesitate.

Other Z-Wave Door Sensors

Technology is always improving and new products are constantly being released. Here is a summary of other door sensors considered, but ultimately left off of the list for various reasons. In the future, these devices or others could evolve into a choice worth considering.

  1. Monoprice Z-Wave Plus Door and Window Sensor – This is a large sensor (3.6 x 2.25 x 1.7 inches) that uses two AAA batteries that the manufacturer claims will last up to 1 year. This device is larger than I would like and there are multiple reports of batteries draining extremely fast. For these reasons, it is not a device I’m considering at this time.
  2. Dome Window/Door Sensor Pro – This is a sensor I wanted to like. It is fairly small compared to other sensors (2.9 x 0.85 x 0.87 inches) and the manufacturer claims a 10 year battery life using an ER14505 3.6 volt battery. The sensor also includes a temperature sensor which is a plus. However, there are a significant number of reviews with people having reliability issues. This device officially works with Wink, so you might want to consider it if that is your home automation platform. I will continue watching this device to see if the manufacturer addresses some of the issues being reported.
  3. Haozee Door/Window Sensor – The Haozee sensor is a low priced sensor that gets a lot of positive reviews. It is a smaller design (2.75 x 0.75 inches) with rounded corners, which might be a preferable look for some users. The device uses one CR2 battery that is rated to last 2 years. Haozee isn’t officially supported by SmartThings, but users state that is pairs to the hub without issue. This is a device I would consider if I needed to add a lot of non-critical sensors throughout a home.


There are a lot of options when consider the best Z-Wave motion sensor for your home. In many cases, you will want to use more than one type of sensor depending on your needs. At this time, I recommend and use these Z-Wave sensors in my home:

  1. Ecolink Z-Wave Door Sensor – This is the primary sensor I use on all the doors in my home. Reliability and battery life has been great over the past several years.
  2. Ecolink Z-Wave Garage Door Tilt Sensor – This is the tilt sensor that I use on my garage door. Again, it has been extremely reliable and I have never had to change the battery.

In my opinion and experience, you can’t go wrong with these two sensors.
