The most frequently asked questions about the installation of the Twinguard
Twinguard - Installation
I installed the Twinguard. Why can't I see any air quality measurements?
The air quality sensor must calibrate itself once. After initial installation, the air quality sensor takes up to two hours to perform initial measurements. Within the first 48 hours after commissioning, a recalibration is carried out in order to optimise the quality of the recorded data. Please note that after about 20 minutes you should either refresh the screen or start the app again so that the current data is displayed.
My Twinguard does not connect to the Smart Home Controller. What can I do?
If you cannot connect your Twinguard, please check the following: 1. Press the control button on the Twinguard for more than four seconds. The Twinguard will then try to connect to the Smart Home Controller again. 2. Try to bring the Twinguard closer to your Smart Home Controller and start the search again. The range of your Smart Home Controller has approximately the same range as your WLAN router. 3. If the previous two steps are unsuccessful, reset the Twinguard to factory settings and start the installation again. Please also see our reset video in this article.

The most frequently asked questions about the operation of the Twinguard
Twinguard - Operations
What is the behaviour of the Twinguard when a battery change becomes necessary?
As soon as it is determined that the Twinguard batteries do not last much longer, the following phases are initiated: 35 days before the battery is empty: A message is displayed in the app indicating that the battery needs to be changed. In addition, the Twinguard LED strip lights up in orange. 30 days before the battery is empty: the detector starts beeping loudly After the second phase, the batteries will last for about 30 days but should now be replaced.
What happens if I remove a Twinguard via the App?
When you remove a Twinguard via the app, all Twinguard-specific data in your Bosch user account in the Bosch Cloud is deleted. This includes all data you entered when you started the system and all historical air quality data recorded over time. Only the Bosch user account you have created will be retained.
My Twinguard no longer transmits air quality data and I have a battery warning in the app, why?
If the battery status of your Twinguard constantly decreases over time, the air quality sensor switches itself off at a certain point in time in order to make the remaining low battery capacity completely available for the smoke alarm protection function.If you see a "battery empty" symbol in the app, you still have at least 30 days of battery life available exclusively for the smoke alarm function. When new batteries are inserted, the air quality sensor activates again automatically. After inserting new batteries, please do not forget to perform a test alarm.
Why do I have gaps in the diagrams of the air quality measurements of the Twinguard?
There are several reasons why the Twinguard's measurements are listed in the diagram with gaps. However, especially if the gaps occur infrequently and for short periods of time, it is not expected to have a negative impact on the overall functionality of the Twinguard. The following reasons are usually responsible for gaps: The smart home controller has been restarted or updated. During the reboot, it is normal to have an approximately 15 minute gap in the diagram. The connection between the Smart Home Controller and Twinguard is not stable. Sources of interference such as Wi-Fi or other electrical devices may be responsible for this. The distance between Smart Home Controller and Twinguard is too large. This can be compensated by an intermediate plug Compact, as this can extend the range. The battery of the Twinguard is almost empty. In order to continue to provide the safety-relevant smoke alarm, the Twinguard automatically deactivates the measurement of the air quality when the batteries are almost empty in order to save energy. The end of the recording history has been reached. Only the data of the last 90 days is kept. The smoke alarm is not affected by the disconnection. However, a connection to the smart home controller is necessary to alert other smoke alarms in the system as well and send a notification to the smartphone.
Can I integrate the Bosch Smart Home Twinguard into the Bosch Smart Home Alarm System?
Yes, the Twinguard can be used in the alarm system. If you have activated the "Alarm System" service (found under menu item "Services"), all connected Bosch Smart Home smoke alarms and Twinguards will emit an acoustic signal. The prerequisite for this is that the "Audible Alarm" action is set to the value "On" in the alarm system. If you have any further questions or problems with the integration, accessibility or use of the device, please contact our .
Can I use my Twinguard in automations?
You can use the various measured values of the Twinguard as triggers for automation. To do this, go to "Scenarios" and then to "Automations". Then select "Add automation". Now select your desired parameter under IF and your desired reaction under THEN. For example: IF "Air quality moderate" THEN select "Smart Plug = On".
I want to move my Twinguard from one room to another. What do I have to consider?
You can "move" a Twinguard from one room to another. Please follow the when disassembling and assembling the hardware. In order to ensure that the new room has both the predefined optimum air quality ranges and the correct alarm sensitivity in case of fire, please carry out the following steps in your Bosch Smart Home App: 1. Remove the Twinguard from the app that you want to install in another room. 2. Reset the alarm to the factory settings. 3. Now add the alarm for the new room where you want to install it. Note: If you move to a new room, the history of the air quality data of the previous room will be lost. You can easily rename the room at any time directly in the Bosch Smart Home App. Please also see our reset video in this article.

General information about the Twinguard
Twinguard - General Information
Which batteries can I use in my Twinguard?
You need six AA size alkaline batteries. Lithium batteries must not be used in the Twinguard. Please only use batteries from Panasonic or Duracell. Please carry out a test alarm after each battery change, either via the Bosch Smart Home App or by pressing the control button on the device itself, to ensure the functionality of your smoke alarm.
According to which standards is the Bosch Smart Home Twinguard certified?
The Bosch Smart Home Twinguard is certified according to the European Standard EN 14604:2005 + AC:2008, and is therefore a reliable life saver in your home.
Which radio protocol does my Twinguard use with the Bosch Smart Home System?
Communication between Twinguard and the Bosch Smart Home System is encrypted using a ZigBee HA 1.2 protocol and proprietary, manufacturer-specific protocol extensions.
What is a Bosch Smart Home Twinguard?
The Bosch Smart Home Twinguard is the world's first 2-in-1 smoke alarm. It is a combined device consisting of a smoke alarm with dual-ray technology and an air quality sensor. With the Bosch Twinguard App you are connected to your Twinguard at any time, whether you are on the road or at home, to be quickly informed of smoke alarms in your home. You can also access your air quality data at any time while on the road. For more information about the Bosch Smart Home Twinguard, please see the corresponding data sheet and the product page.
Does the Bosch Smart Home Twinguard also work when it is not connected to the App and Smart Home Controller?
If the Twinguard is not operated as a smart smoke alarm with Internet connection, a reduced range of functions is available. In this case the Twinguard can only display fire alarms as a local smoke alarm. In this case the alarm is not forwarded to other Twinguards and Bosch Smart Home smoke alarms in the country.
What significance do the room types have (Twinguard, fire alarms, air quality)?
As a smoke alarm and air quality sensor, the Twinguard has various setting options that are specified by the manufacturer and designed for the corresponding rooms. Smoke alarms: The sensitivity of the smoke alarm is determined by the room types. For example, the Twinguard is less sensitive to disturbances such as kitchen fumes for the "kitchen" room type. In the room types "bedroom" and "children's room" the Twinguard Dual-Ray detector reacts with the highest possible sensitivity. Air quality: Depending on the type of room, different ideal ranges are specified for the air quality parameters. The ideal ranges for each room type can be seen from the green areas in the air quality diagram. For bedrooms, for example, lower temperatures are provided as the ideal range than for study rooms.
What is the smallest and the largest displayable measured value (Twinguard)?
The lower limit of the installed sensor (BME680) is a value of 500 ppm. The highest detectable value is 5500 ppm.For both limit values, an error tolerance of approx. +/- 15% must be taken into account. The built-in sensor cannot detect all organic components in the air (as is usual for such sensors). Therefore it must make assumptions about other air components depending on the gases detected. The best value of 500 ppm is also delivered after a restart (or directly after learning) until the calibration allows more accurate values. This process can take up to about one hour, depending on the environment.
How often are measured values generated by the VOC sensor (Twinguard)?
The VOC sensor constantly calibrates itself to provide the best possible values in the environment used. The algorithm uses historical data of the last 4 days. If the environment of the sensor is suddenly changed (e.g. outdoor installation), the effect will not necessarily be as expected. A short-term adjustment of the mounting location therefore falsifies the data basis for the auto-calibration at the actual destination. If possible, the Twinguard should therefore be operated at the same location for a few days before the values are used to interpret the functionality. It can be assumed that approximately 120 readings are taken over a period of 10 hours.
How long is my air quality data stored in the Bosch Cloud (Twinguard)?
Bosch Smart Home stores your data in the Bosch Cloud for 3 years. This gives you retroactive access to your recorded air quality history for 3 years, after which it is automatically deleted. You can also delete your data at any time before that. For example, by resetting the system to factory settings and removing the components - from the Bosch Smart Home App.
