Aeotec Door Window Sensor 8 Review: A Z-Wave Long Range Contact Sensor That Also Watches Tilt, Temperature and Humidity
The Aeotec Door Window Sensor 8 is a Z-Wave Long Range contact sensor for people who already run a Z-Wave hub such as Home Assistant with Z-Wave JS or SmartThings. Beyond open and close it reports tilt from a 3-axis sensor, temperature, humidity, dew point and a mold hazard alarm, and it can run on a CR14250 cell or stay on USB-C power. The trade-offs are that it needs a Z-Wave controller, has no Apple Home or Matter path and is rated for dry indoor locations only. For a Z-Wave home it packs more sensing into one door or window than a plain contact sensor.
- Z-Wave hub owners
- Home Assistant setups
- Tilt-and-turn windows and garage doors
- Indoor climate monitoring
Pros
- Z-Wave Plus Long Range on an 800 series chip with S2 security and SmartStart
- 3-axis tilt detection on top of the magnetic open/close contact
- Built-in temperature and humidity sensing with dew point and mold alarm
- Optional USB-C power, which also turns it into a Z-Wave repeater
- Tamper and low battery notifications
- Works with Home Assistant through Z-Wave JS and with SmartThings through Aeotec's Edge driver
Cons
- Needs a Z-Wave hub; no Wi-Fi, Zigbee or Thread
- No Apple Home or Matter support
- CR14250 cell is less common than coin cells
- IP20 rating limits it to dry indoor locations
- SmartThings needs a custom Edge driver for every feature
Who is the Aeotec Door Window Sensor 8 for?
It is built for homes that already have a Z-Wave controller. Aeotec documents pairing with Home Assistant through Z-Wave JS, with SmartThings and the Aeotec Smart Home Hub through its own Edge driver, and with its AutoPilot software, and the sensor speaks Z-Wave Plus Long Range on an 800 series chip, so it can sit far from the hub in a detached garage or a large house. Without a Z-Wave hub it does nothing on its own: there is no Wi-Fi, Bluetooth, Zigbee or Thread radio.
What the Aeotec Door Window Sensor 8 offers
The magnetic contact handles the classic open and close job, and a 3-axis sensor adds a tilted state, which suits European tilt-and-turn windows, skylights and garage doors; the tilt trigger angle can be set from 1 to 90 degrees. The same small body (70 x 18 x 19 mm) measures temperature and humidity, reports the dew point and raises a mold danger alarm when humidity stays high, with configurable high and low temperature alarms on top. It sends tamper and low battery notifications, and its Z-Wave association groups can switch other Z-Wave devices directly, for example turning off a heater when a window opens. Power comes from one CR14250 cell, which Aeotec rates at about four years, or from an optional 5V USB-C supply, in which case it also works as a Z-Wave repeater.
What to know before you buy
A Z-Wave hub is required, and the ecosystem story runs through that hub: SmartThings needs Aeotec's custom Edge driver to expose every reading, Alexa only sees it through a hub that has an Alexa skill, and there is no Apple Home or Matter support. The CR14250 is a half-length AA lithium cell that is less common in stores than coin cells, and Aeotec's own technical sheet quotes up to two years at the default settings, so frequent tilt or climate reports will shorten it. The housing is rated IP20 and meant for dry indoor locations only, so it is not a sensor for an exterior gate.
Is the Aeotec Door Window Sensor 8 worth it?
For a Z-Wave home, yes when you will use more than the contact: tilt, climate and mold alerts in one mid-range sensor replace a separate temperature and humidity sensor on that window. If all you need is open and close, or you do not run Z-Wave, a simpler and cheaper contact sensor on the protocol you already use makes more sense.
Frequently asked questions
Does the Aeotec Door Window Sensor 8 need a hub?
Yes. It is a Z-Wave Plus Long Range device, so it needs a Z-Wave controller such as Home Assistant with a Z-Wave stick, SmartThings or the Aeotec Smart Home Hub, or another Z-Wave gateway.
Does the Aeotec Door Window Sensor 8 work with Home Assistant?
Yes. Aeotec documents pairing it through Z-Wave JS, and the Z-Wave JS device database lists the ZWA055 in its EU, US and AU versions, exposing open/close, tilt, temperature, humidity and battery.
Can it detect a tilted window?
Yes. A 3-axis sensor reports a tilted state in addition to open and closed, and the trigger angle can be configured from 1 to 90 degrees, with 5 degrees as the default.
What battery does the Aeotec Door Window Sensor 8 use?
One CR14250 (3V, 1500mAh) cell, rated by Aeotec at about four years, with up to two years quoted at the default settings. It can also run on an optional 5V USB-C supply, keeping the battery as a backup.
Does it work with Apple Home or Matter?
No. It is a Z-Wave sensor with no Matter or Apple Home support, so it reaches other ecosystems only through a Z-Wave hub.
Can I use it outdoors?
No. It is rated IP20 and Aeotec says it is intended for indoor use in dry locations only.
