- Insert the sensor into the waterproof case, by opening it on the back side as shown below:
Can I use the ZSE41 on a door or window with a metal frame?
- Not recommended. Metal elements are a big disrupter of Z-Wave signals, but you could try to add a wooden spacer on the surface of where the sensor is installed. We have not verified this will ensure the reliability of the sensor with a wooden spacer.
What is the operating temperature of the ZSE41?
- 32° – 104° F
What are the dimensions of the ZSE41? How big is the device?
- 1.9” x 1” x 0.3” (magnet: 1.26" x 0.3" x 0.3")
- Magnet to sensor max gap: 0.25"
What is the wireless range of the sensor?
- Z-Wave devices work best in a mesh network, so even though the sensor has a range of up to 300 feet line of sight, this means 300 feet with other Z-Wave signal repeating devices between where the hub is and where the sensor will be installed.
- It is the hub that decides the communication route to each device. The more signal repeating (non-battery powered) devices included on your network, the stronger it is and easier it is for the hub to reach devices that are further away.
- Environments with a lot of glass or metal elements, large furniture, and thick walls can also be very disruptive to Z-Wave signals.
- Basic glass can easily be penetrated by wireless signals including Z-Wave, but with double or triple pane glass windows it will reduce the strength of your Z-Wave signals. If your glass window is treated against emissions and radiation (these are typically present in new buildings as a standard so make sure to determine that before attempting, tilts, films, or glazes may be a indication of that), these can be highly reflective and block/reflect Z-Wave signals.
What kind of battery does the ZSE41 use / need?
- The ZSE41 sensor is powered by a single CR2032 battery.
- We recommend using Energizer, Panasonic, or Maxell brand batteries which are confirmed to work well in the sensors. Our techs have been looking into a battery issue with the XS sensors and have confirmed that for an unknown reason at this point, Duracell batteries are not working well to power the XS sensors.
- While CR2032 batteries can technically operate down to -22F, cold temperatures reduce ion mobility, increasing the batteries' internal resistance and dropping the output voltage. No energy storage is lost, it's just that the energy doesn't get to the device, it dissipates internally. So in cold weather it may stop responding, but once it warms up, it should still operate and respond. The sensor needs a certain amount of voltage from the battery to report, and when that energy is dissipated due to the cold, you get a loss of function until the battery is warmed.
What is the battery life of the ZSE41?
- You should get around 12-14 months out of the ZSE41 XS sensor with normal use.
Can I use rechargeable batteries?
- We don't recommend it. Rechargeable batteries usually decrease in max voltage with time, so you may see a shorter battery life if using these. The Z-Wave chip manufacturer also requires all Z-Wave devices to report low battery at 2.6V and many rechargeable batteries are not full 3V when charged so it may seem like the battery is empty even at full charge.
What voltages should the battery report for 100% and when there is a low battery alert?
- 3.2V - 3V is a full battery (100%) and the Z-Wave chip manufacturer requires all Z-Wave devices to report low battery at 2.6V.
How do I get the most battery life out of my ZSE41 sensor?
- We recommend pairing Z-Wave devices to your hub without security (if your hub lets you choose during inclusion). S2 security adds an additional layer of information to communicate with your hub which can drain the battery quicker than you'd like, in rare cases.
Why is the battery level fluctuating so much? / Why was the battery drained a lot during set-up?
- This sensor runs on a coin battery with smaller capacity than the lithium CR batteries used in other sensors, so you may see the battery readings fluctuate from low to higher readings when the sensor is awake during programming and testing. The battery will usually go back to its stable reading within a few hours so always allow a day or two after you see the first lower reading before checking on the actual battery life left for your device.
What is the warranty coverage for the ZSE41?
- Zooz 700 and 800 series devices are covered by a 5-year warranty. Please register your device here and review the full warranty policy here.

PRODUCT FUNCTIONALITY QUESTIONS
Does the ZSE41 have internal contacts to connect to a wire, like an external reed switch?
Is the reed switch on the ZSE41 normally open or closed when the magnet is not present?
- The sensor will report as open if the magnet piece is away from the sensor.
Is it possible to configure it to use both sides at the same time, so that if either side opens it registers as open?
- You can use the ZSE41 sensor with 2 magnets, but it will show the status as closed if either of the magnets is close to the ZSE41 (though only one magnet is included).
Will the ZSE41 act as a signal repeater for other Z-Wave devices in my network?
- No. Battery powered devices will not act repeaters. Your Z-Wave hub decides which devices to use to reach other Z-Wave devices. Any non-battery powered Z-Wave device will act as a signal repeater; it would be up to your hub whether or not it will be used in a communication route.
Do I need a Z-Wave hub to buy this device?
- Yes. The ZSE41 sensor is a Z-Wave device which would need a Z-Wave hub in order to send open | close reports and customize advanced settings.
- To control or monitor any of our Z-Wave devices remotely through your smart phone, you'll need a compatible Z-Wave hub. These devices require a central controller that communicates with them and sends commands. Once you have a controller, you would download that controller's dedicated app on your phone and control your connected devices through that app.
Is the ZSE41 sensor compatible with my hub?
- You can find a list of compatible hubs for a given device under the Works With section on the product's page. Here is the list of hubs compatible with the ZSE41.
Will this sensor work with my alarm panel?
- Alarm panels like Alarm.com will typically only support single switches, door locks, select thermostats, and any authorized items on their list. We would recommend reaching out to your alarm panel company to verify compatibility and to get the latest on any device integrations they may be working on.
- To our best knowledge, most alarm panels don't support binary sensors so the ZSE41 may not display correctly in their interface. There is nothing about the Open | Close Sensor that we could change to improve compatibility with alarm panels, since this is a limitation of the hub and how it supports binary sensors. It would be up to your alarm panel to integrate the device, as it follows Z-Wave protocol and has been Z-Wave certified. There is nothing we can change on our end to have the device be recognized correctly. Read more about alarm panel compatibility here.

How can I tell what firmware my ZSE41 is running on?
- The firmware that your sensor is shipped with should be printed on the back of the device where the model specifications are. If your hub supports and properly integrates the device, you should also see the firmware listed in your Z-Wave interface.
- Firmware that is listed as 1.01 (or any other value with a 0 in the middle) in the sensor's change log may display as 1.1 in your hub.
How do I update the firmware of my ZSE41 sensor?
- Some Z-Wave hubs have a built-in firmware updater that you can use. Otherwise, we recommend using the PC Controller tool on the Simplicity Studio Software as described here. You will need to register your device in order to have access to Zooz firmware files.
How long does the update take? How do I know when it's finished?
- Firmware updates should usually take anywhere from 5 to 15 minutes depending on connection quality and how much information needs to actually be updated on a given device.
- If it is taking longer than that, please try to bring the hub / controller closer to the device that is being updated.
Where can I find the history of changes and firmware updates for the ZSE41?
What series Z-Wave chip does the ZSE41 use?
- The ZSE41 uses a 700 series Z-Wave chip. We are in the process of updating this model to the new 800 series Z-Wave chip so it should be 800 series by the end of 2023.
Is the ZSE41 available in other Z-Wave frequencies?
- The ZSE41 is currently available in 908.42 MHz (US, CA, MX), 921.4 MHz (AU, NZ), and 868.42 MHz (EU) frequencies.
