ZSE40 4-in-1 Sensor


Can the ZSE40 be installed outdoors?

  • NO.

What is the operating temperature of the ZSE40?

  • 5° - 104°F

What are the dimensions of the ZSE40? How big is the device?

  • 2.25" x 2.25" x 1"
  • Weight: 2.0 oz

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.

What kind of battery does the ZSE40 use / need?

  • The ZSE40 sensor is powered by a single CR123A battery.

Will it work in environments colder than what it is rated for?

  • Cold temperatures can 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 ZSE40?

  • You should get around 14-18 months out of the ZSE40 700 series 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.

Can the ZSE40 be powered by USB power?

  • No, the ZSE40 only supports battery power. For a USB powered multi sensor, you'll want to check out the ZSE11 Q Sensor.

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 ZSE40 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.
  • If your priority is motion, you can change some of the advanced settings so that the unit reports less for the other values:
    • Temperature Change Threshold: Parameter 2 to Value 50, Size: 1 byte dec
    • Humidity Change Threshold: Parameter 3 to Value 50, Size: 1 byte dec
    • Lux Change Threshold: Parameter 4 to Value 50, Size: 1 byte dec
  • If you're not using the LED indicator on the device itself, you can also disable this to conserve battery: Parameter 7, Value 1, Size: 1 byte dec
  • Once you make any changes to the advanced settings, we recommend waking up the unit manually by pressing the Z-Wave button once with a paperclip. This will help ensure the changes go through immediately.

What is the warranty coverage for the ZSE40?

  • Zooz 700 series devices (like the ZSE40 700) are covered by a 5-year warranty. You will see 'ZSE40 700' printed on the back of the device to verify the exact version. Please register your device here and review the full warranty policy here.
  • Zooz 500 series devices (like the ZSE40) are covered by a 12-month warranty. You will see 'ZSE40' printed on the back of the device to verify the exact version.

Where can I find the ZSE40 device manual?


What value represents insufficient light such that you would want a light to turn on?

  • The sensor reports the light level to the hub in percentage which is then converted to lux on select platforms (100% daylight is the equivalent to around 50 lux so it will max out at this value). For insufficient light, we would recommend trying programming automations when the sensor is at 20lux or lower.

How does the ZSE40 sensor work?

  • The sensor checks for ambient changes every 3 minutes and will only report these changes to the hub if any of the sensors meet the reporting threshold. To increase the reporting time of temp, humidity, and light, you would need to decrease the reporting thresholds for each of the sensors in the advanced settings. The sensor will not report any other values when reporting motion. It will report the change once the motion has cleared.

  • There's currently no way to set a reporting frequency based on time. The check-in interval in the settings refers to the wake-up time which is how often the sensor will wake up to received messages from the hub (like new settings). We recommend leaving it at 12 hours to improve battery life since this setting doesn't affect how often the sensor reports to the hub.

  • Read more about the ZSE40's reporting functionality here.

What does Parameter 8 do on the ZSE40 700 device?

  • If you're on firmware 32.02 or higher, parameter 8 will allow you to disable basic set reports being sent to the hub, keeping just the notification reports. If you'd like to disable the basic set reports, please set the parameter to value 0 (size 1 byte dec).

What is the difference between the ZSE40 4-in-1 Sensor and ZSE11 Q Sensor?

  • The ZSE11 has a smaller lens so the detection range will be smaller than on the ZSE40.
  • The ZSE11 is much quicker and accurate to report lux levels and it will also report temp and humidity while detecting motion while the ZSE40 will not report any other values as long as motion is detected.
  • The ZSE40 will also update every 3 minutes at most while the ZSE11 will report changes quicker.
  • If your main use case is motion or temperature, the ZSE40 a better fit. If it's lux / humidity changes detected while motion activity is also present, the ZSE11 will be a better fit.
  • More info about the ZSE40 and ZSE11 differences here.

It takes 10-20 seconds for the sensor to detect motion again after changing back to 'no motion detected' status - is that normal?

  • Yes. Any Z-Wave motion sensor will have a cooldown period of 10-20 seconds depending on the brand. A Z-Wave motion sensor will not act like your typical hardwired security sensor from an alarm panel which does not have a cooldown time. This cooldown period was implemented for two reasons:
    • To save battery life
    • To not overflood the Z-Wave network with unnecessary reports.

Will the ZSE40 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 ZSE40 sensor is a Z-Wave device which would need a Z-Wave hub in order to receive the motion, temp, humidity, and light 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 ZSE40 sensor compatible with my hub?

Will this sensor work with my alarm panel?

  • NO. Alarm panels like 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 multi sensors so the ZSE40 won't display correctly in their interface. There is nothing about the4-in-1 Sensor that we could change to improve compatibility with alarm panels, since this is a limitation of the hub and how it supports binary and multi 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.

Where do I find all of my sensor's advanced settings?

How do I add the sensor to my Z-Wave hub?

How can I tell what firmware my ZSE40 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 ZSE40 sensor?

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 ZSE40?

What series Z-Wave chip does the ZSE40 use?

  • The ZSE40 700 uses a 700 series Z-Wave chip. This model is soon to be discontinued in favor of the ZSE11 Q Sensor.
  • The ZSE40 is a discontinued model that used the 500 series Z-Wave chip.

Is the ZSE40 available in other Z-Wave frequencies?

  • The ZSE40 is currently available in 908.42 MHz (US, CA, MX) and 921.4 MHz (AU, NZ). It was available in 868.42 MHz (EU) frequency, however it is out of stock and we will not receive more inventory in this frequency.
