We have summarized the most frequently asked questions below. If you can't find a suitable answer to your question, feel free to send us an e-mail: support-spexor@bosch.com


How can I see if my alarm device is activated or deactivated?

You will receive a push notification when your spexor has been successfully activated or deactivated. Apart from that, you can check the status on the start screen of your app under "Surveillance Mode".

It can take a long time until my alarm device is activated. Why is that?

To make spexor mobile, we have taken some measures to increase the runtime of its battery.

In mains operation (charging cable is connected to the power supply) spexor is notified every 2-3 minutes whether you have activated or deactivated it. This means that in mains operation it can take 2-3 minutes until spexor responds to the entries in the app.

In battery mode, spexor is notified every 15 minutes whether you have activated or deactivated it. This means that in battery mode it can take up to 15 minutes until spexor responds to the entries in the app.

The background is that every hit in the backend requires battery life, so we have deliberately performed field tests to test these times so they are not too long, but also not too short.

If you can’t or don’t want to wait this time, it is also possible to activate spexor directly via PIN entry.

You will receive a push notification when spexor has been successfully activated or deactivated.

Why does my device update not start immediately?

Since spexor gets the update information from our server, it may take some time until the update actually starts visibly to you.

You should expect a delay of about 15 minutes if you want to start the update using spexor in battery power mode. If you connect spexor to the power, the update can be started with a delay of max. 5 minutes.

Our recommendation: Connect spexor to the power supply before you start the update.

Update via WiFi does not work. Do I have another possibility?

If WiFi does not work or is not available, you another option:

  • Turn off the alarm device for at least 1 hour by pressing the button
  • Open the app while spexor is switched off
  • Start the update in the app while spexor is still switched off
  • A pop-up should appear now that allows you to update via Bluetooth
  • Before you select "start with Bluetooth", switch spexor on and activate Bluetooth on your smartphone

Where can I see whether my spexor is connected to WiFi or not?

We currently do not have the information about whether spexor has an active WiFi or mobile network connection. We will check whether we can make this information visible to you in one of the next app updates.

Whenever spexor does not have an active WiFi connection, it automatically uses the integrated mobile phone.

Where can I see if my spexor has an active mobile network connection?

We currently do not have the information about whether spexor has an active WiFi or mobile network connection. We will check whether we can make this information visible to you in one of the next app updates.

You can restart spexor at any time or set up spexor at a different location: close to a window, in another room or try it outdoors.

In general, spexor uses provider roaming. That means we access all major mobile networks: Vodafone, Telekom, and Telefonica (O₂).

Important: The display on your smartphone does not always guarantee the availability of the network spexor uses, as we use 2G or GSM, unlike your smartphone.

Why does spexor not find my WiFi?

Sometimes older devices have difficulties in finding networks, especially with so-called "invisible" networks. This problem is particularly noticeable in company networks, as these networks - not easily recognizable - are often additionally secured. In the case of guest networks, a query or request to agree to the terms of use of these networks may appear (check the box, press the button, etc.). Such networks are not suitable for spexor.

If you are currently in the setup process, continue with mobile network and add your WLAN after the device update.

What else you can do:

  • Go in and out of your wireless settings several times to trigger a new network scan
  • Check if the 2.4GHz network (not 5GHz) is switched on at the router
  • Try another network: This can also be a hotspot over another smartphone
  • Restart the device right before you start the setup process

Why is the double-tap not working?

We learned that a double-tap can work in many different ways.

Therefore, we replaced the double-tap. From now on, you can deactivate and activate your device by entering the PIN on the keypad. This is very easy: turn spexor 180 degrees upside down, enter your PIN and shortly after that, the monitoring is activated.

The most important thing is that you have activated spexor at least once via the app before you try the activation by PIN.

Simply update the app in your store and run the device update in your spexor app. spexor will restart automatically.

Important: WiFi or mobile connection must be available when activating the device.

What do the lights and the flashing mean?


Continuous light-up: Smartphone and app are connected to spexor via Bluetooth®.


Short continuous light-up: Switch on at the ON/OFF switch.

Short flashes: spexor is still switched on if it is touched or moved while monitoring is deactivated.

Short flashes every 30 seconds: spexor is active when monitoring is activated.

Three flashes sequentially emitted all around the LED array bar: Power supply unit has been detected and charging begins.


Six flashes sequentially emitted all around the LED array bar: spexor boots up after switching on.

Pulse for 60 seconds: Indicates sensor calibration after monitoring is activated as well as the remaining time to leave the monitored room.


Flashing: The alarm is triggered.

Short continuous light-up: Switch off at the ON/OFF switch.

Why is Bluetooth not working?

Deactivate Bluetooth on your smartphone and then reactivate it.

However, the stability of Bluetooth varies depending on the smartphone provider. It is possible that Bluetooth may work more reliably on Apple and Samsung devices.

If you contact our support on this topic, please include your smartphone model, the version of your operating system and the version (under "Device Settings": "Updates") of your spexor.

The key pad of my alarm device do not work.

Before you enter your PIN turn your spexor by 180°. The function to enter your PIN is now activated.

Can I change the alarm tone of the push notifications or adjust settings?

We have implemented custom tones for many messages in the app. The volume can be adjusted via the system volume of your smartphone.

The length of the push notification alarm tone cannot yet be customized. We are checking if we can provide you with this option in an upcoming update.

Can I change the alarm sound from the alarm device?

No, the alarm tone is predefined by the hardware.

Why does spexor seem to sound the alarm only after a delay? Why do I receive the push notification with delay?

With Android smartphones, especially Huawei and Honor, in case of a break-in, you may receive the push notification with delay. This is due to the devices' power saving mode, which can block these notifications. Please adjust the power saving mode in the settings of your smartphone. You can find out how this works in the user manual from your manufacturer.

spexor only emits an acoustic and optical signal once the alarm message has been sent. To do this, a connection must first be established via WiFi or mobile network, which can take a while depending on the connection strength and network coverage. spexor detects faster than it can transmit.

How quickly the connection is established also depends on the 2G network coverage at the respective location. If spexor is unable to find a 2G mobile network connection, it automatically sounds an acoustic alarm and continues to attempt to establish a mobile phone connection in parallel.

Please Note: The 2G network coverage is not the network coverage that is usually displayed on the smartphone (LTE, 3G, 4G...)

How can I activate spexor with the PIN?

Turn spexor 180° upside down, enter your PIN and shortly afterwards the monitoring is activated.

Important: please activate the monitoring at least once via the app before you try to enter your PIN.

It is also important that either WiFi or mobile network is available when activating the monitoring, otherwise spexor cannot send an alarm.

How does spexor use GPS? Why do I have to enter my location?

Your location affects the sensitivity of the sensors as well as the transmission of GPS data: If you select a fixed location, such as your home or garden shed, spexor will use the entered address, as buildings often have a poor GPS signal.

When you choose a mobile location like your car, spexor uses GPS data without a stored address. Therefore, it is important to define the correct location whenever you are on the road.

Please define the location before activating the monitoring or add a new location if necessary. Just click on your current location in your app, select the appropriate environment or add a new one using the "Edit" function (top right).

What is the difference between the app version and the device version?

For spexor two software programs are relevant for you:

The app software: You can find the latest version in your spexor app under the menu item "Account" and also in the app stores. This is where you can also check if the app needs to be updated.

The device software (so-called firmware): You can find the latest version of the firmware in your spexor app under "Device Settings" "Device Update". This is where you can also see if your spexor already has the latest firmware or if an update is available.


In which countries will spexor be available?

spexor will be sold in Germany first, but the product can also be used in the EU, e.g., when traveling. Sales will begin in other countries at a later date. Check our website for updates.

Possible usage applications

What are the minimum requirements for my smartphone?

It doesn’t matter how your smartphone is equipped or what kind of cell phone contract you have. spexor has its own mobile phone module that includes an eSIM card and can therefore be used wherever mobile phone reception is possible. That’s what makes it so flexible in use.

Can I set up several devices in one residence?

Yes, each alarm device can monitor a specific room or area (e.g. staircase and entrance hallway). The range of the sensors covers a radius of 5 meters around the device – as long as no obstacles such as walls, high furniture, etc. interfere with the sensors.

Can I use spexor if I have a pet?

Pets such as cats or dogs can trigger the alarm. Of course, it is not a problem if you can position spexor such a way that it does not detect your pet (e.g. in a closed room). We have already put pet recognition on our roadmap for upcoming product generations.

Where can I use spexor?

You can use spexor almost wherever you need it! For example, in a vehicle, at home, in the garden shed, garage or the mobile home. Of course, spexor can also safeguard what is important to you in many other places. It doesn’t matter whether it’s your hotel room or the vacation residence when you are traveling or the workshop or the bicycle shed – creativity knows no bounds here! The only criteria are that WiFi or mobile phone reception is available and that the monitored area is an indoor space.

Can I use spexor in addition to other alarm systems?

Yes, that will work. Bear in mind that spexor is always operated independently of any other alarm system installed, but it can always offer supplemental protection for your desired location.

Please note: under no circumstances is spexor a replacement for a specialized, comprehensive, or permanently installed alarm system.

Is spexor a certified alarm system?

Please note that spexor, consisting of the app and the device is only intended for use in your everyday environment and is under no circumstances suitable for use in particularly critical areas. The devices, data backend and app have not been certified as in compliance with industry regulations or standards, in particular not in accordance with standard EN 50131.

Can spexor also be used in convertibles, tents, boats or with 2-wheelers?

spexor can only be used in enclosed spaces so that the sensors for noise, pressure and movement can react reliably to changes within the environment.

In principle, the device could also be used in enclosed spaces on boats, but it is not seawater-proof. A maritime version is already being considered.

About spexor

How are spexor and Bosch related?

spexor is a corporate start-up at grow platform GmbH which is a Bosch-internal platform for corporate start-ups and is 100% owned by Bosch. New business areas that promote innovative ideas are developed here.

What is the Bosch ID?

The Bosch-ID is an authentication system of the Robert Bosch GmbH, which is used in many Bosch products or Bosch internet pages. In simple words: It is only used for login.

Your user name and password are managed securely. Many Bosch products and services already use the central Bosch ID and from now on you have the possibility to access them with only one login.

Smart Home

Is spexor compatible with Bosch Smart Home or systems like Alexa?

spexor already has Zigbee and our device should be compatible with other smart home systems like Bosch Smart Home, Home Connect Plus, Alexa or Google by the end of 2021.

We intend to make this function available to all spexor users with a software update.

Physical components

Is spexor available in different colors?

spexor will also be available in different colors in the future. This way you can choose exactly the alarm device that best suits your usage purpose and environment.

How big is spexor?

spexor is 12 centimeters (4.7 inches) high and has a diameter of 7 centimeters (2.75 inches) at its widest cross-section.

How much does spexor weigh?

spexor weighs just 320 grams (11.2 ounces).

Is there a protective cover for spexor? Is it included or available separately?

At the moment we do not have protective covers in our portfolio, but we are already working on them.

Is a mechanical mount in vehicles or for wall mounting available?

We don't have a mechanical mount yet. However, it is being considered that future alarm devices can also be firmly mounted (from 2022).

Why does spexor use Micro-USB instead of USB-C?

A Micro-USB is more gentle on the battery and thus enables a longer operating time, whereas a USB-C also consumes power by itself.

Technology – there’s more to it than you think

Are additional functions planned?

spexor can already detect burglaries at the start of sales. We are working for you on the detection of further hazards such as the detection of dangerous gases, which will be available with upcoming extensions. In addition, your spexor will be able to measure and display air quality. These functions can then be easily added as in-app purchases.

Does spexor deactivate itself automatically when you come home?

No. To deactivate the alarm device, you need your smartphone or the 4-digit PIN that you have set in advance.

How can one deactivate spexor without a smartphone?

This is possible with a 4-digit PIN which is entered on the keypad on the bottom of the alarm device. You can define the PIN in the app as you like.

How does localization work with spexor?

We have a GPS module with an active antenna. Additionally, we also use the address data you enter to specify the different locations.

How long does the spexor battery last?

spexor comes with a very powerful battery that can tolerate temperatures ranging from –10 °C to +60 °C. After you have charged it via the Micro-USB port, spexor monitors your environment for several weeks – the actual duration of the battery’s charge depends on the ambient temperature, among other things. As soon as the battery needs recharging, spexor sends a message to you on your smartphone and you can control the battery status in the app.

What does the future of GSM (2G) look like?

GSM (2G) will be available in Germany for the next 5 years and currently offers the best area-wide network availability. The same applies to other EU countries.

Is the alarm from spexor loud and visible in any case? Can I turn the alarm sound louder?

You decide by yourself how spexor should react in case of an alarm. The alarm device itself can give an acoustic sound to show potential burglars directly that you have caught their attention. Or it remains silent and informs you discreetly. Even after the alarm, you decide how to proceed. You can check the situation yourself or, for example, ask neighbors and friends for help and, in an emergency, inform the police. We are working on the option of being able to switch off the optical signal as well.

The volume of the alarm is based on the relevant standards such as EN ISO 7731:2008. The perceived volume of the alarm tone also depends on the sound pressure and frequency of the tone. However, it should be noted that the alarm tone is deliberately not chosen that loud, so the entire neighborhood is in turmoil, but "only" signals to the burglar: "You have been caught".

With the new software release (Version 1.0.56) we integrated a more deterrent alarm sound.

Where is my personal data stored?

The data is stored and processed in Bosch’s own server landscape (back-end).

Is it possible to replace the battery in spexor?

The battery is not intended to be replaced. The battery quality is designed to support a sufficient charging capacity.

Why do I receive alarm messages when there is strong sunlight in my parked vehicle?

Sudden temperature differences in the air can trigger an alarm. This is a fundamental, technically caused problem of all infrared sensors, which by definition react to heat. To avoid such situations we plan to adjust the evaluation of sensor data in spexor and are already working on this. Later, an update of the device can adopt the new sensor settings, without the need for a new device.

Can I charge my spexor with a different charger or connect it to a power bank?

Charge the battery of the alarm device only with the charger supplied by the manufacturer. If a charger that is suitable for a certain type of battery is used with other batteries, there is a risk of fire and no warranty can be given. A power bank can theoretically be connected to the spexor. However, in this case the warranty will be void.
