TECHNICAL FIELD

Embodiments herein relate to automation and/or monitoring systems for venues, such as homes, offices or the like. In particular, a method and a computing function for managing a risk factor relating to damages to the venue are disclosed. A corresponding computer program and a computer program carrier are also disclosed.

BACKGROUND

There exists various home automation and monitoring systems that warns the user about different errors as they happen.

Existing system provide information about which sensor or the like caused the alarm. A homeowner then commences a cumbersome error finding process, which typically is both time consuming and costly, e.g. in terms of continued worsening of damage during error finding, hourly rate for error finding if applicable, or the like.

US10198771B1 discloses a system for receiving data from one or more sensors or devices associated with one or more users. In some examples, data may be filtered and analysed to determine a risk profile for a user. In addition, the system may also determine a neighbourhood risk profile for a number of users located in the same geographical location. The risk profile and the neighbourhood profile may be used to determine or adjust a user's insurance premium. A disadvantage with the aforementioned system may be that it may be frustrating for the user to experience how the insurance premium varies, especially increases, as time passes by. Moreover, once a damage happens, or risk thereof increases, the user may need to perform tedious and/or difficult investigations to at least reduce the damage, or risk thereof.

SUMMARY

An object may be to at least reduce one or more of the aforementioned problems and/or disadvantages.

According to an aspect, the object is achieved by a computer-implemented method for managing a risk factor relating to damages to a venue. As an example, the method may be performed by a computing function, such as a server, a computer, a cloud function, a server-less function or the like.

The computing function receives, from a sensor device monitoring a system of the venue, a first message indicating malfunction of the system. The system is related to the risk factor. The computing function analyses operation history indications of a set of candidate sources of the system to obtain a primary source of the set of candidate sources. The computing function provides, to a person associated with the venue, a second message indicating the primary source, thereby inviting the person to check whether the primary source is the cause of the malfunction or not.

Thanks to the computing function analyzing the operation history indications of the set of candidate sources of the system that is indicated as malfunctioning according to the first message, the computing function is able to obtain the primary source, e.g. a probable source of the malfunction detected by the sensor device. Then, the computing function provides the second message in order to indicate to the user that the primary source may be checked. As a result, the computing function may enable a reduction of the risk factor, since the probable source of malfunction may be checked and appropriate actions may be taken without unnecessary delay.

Accordingly, based on a relatively generic error message as provide by the first message, an indication of source of error, such as by providing the primary source, may be indicated to the user. As a result, a faster and less costly error finding process may be enabled.

An advantage is, hence, that the user is assisted, by the computing function, in finding the primary source, causing the first message. As a result, a cumbersome and time consuming error finding process may be avoided, or at least greatly simplified. For example, time spent in the error finding process may be reduced. Hence, in many scenarios, such as when error finding is bought, e.g. by an owner of the venue, as a service, also reduced expenses for the error finding process is expected.

According to further aspects, the object is achieved by a computing function, a computer program and a computer program carrier corresponding to the aspects above.

Along with the description below a few exemplifying examples will be described for purposes of illustration.

In a first example, the system 200, 300 comprises a tap water pipe system of the venue 100.

In a second example, the system 200, 300 comprises an electrical system of the venue 100.

One or more of the following actions may be performed in any suitable order.

Action A010

The sensor device 240, 340 sends a first message to the computing function 110. The first message indicates malfunction of the system 200, 300. The system 200, 300 is related to the risk factor. More generally, the first message may indicate an event related to the system 200, 300. The sensor device 240, 340 may monitor one or more systems 200, 300 of the venue 100.

Action A020

The computing function 110 receives, from a sensor device 240, 340 monitoring a system 200, 300 of the venue 100, the first message.

According to the first example, the first message may indicate malfunction of the tap water system 200, e.g. by means of that the sensor device 240, such as a drip sensor device, detects a leak and thus sends the first message, which e.g. indicates dripping or leaking water in the tap water system 200.

According to the second example, the first message may indicate malfunction of the electrical system 200, e.g. by means of the sensor device 240, such as a sensor device monitoring fuses of the electrical system, detecting that a fuse has released, such as blown, and thus sends the first message, which e.g. indicates that the fuse of a particular section or group of the electrical system has released.

Action A030 The computing function 110 analyses operation history indications of a set of candidate sources 210, 220, 230, 310, 320, 330 of the system 200, 300 to obtain a primary source 210, 310 of the set of candidate sources 210, 220, 230, 310, 320, 330.

The operation history indications may relate to, such as specify, comprise or the like, at least one of water consumption, water flow, water pressure, temperature, air quality, air flow and electricity consumption of the corresponding candidate source 210, 220, 230, 310, 320, 330 or the like.

The operation history indications may relate to a time period prior to the first message, and optionally also to a time period after the first message if available. The time period may be any suitable time frame, such as one or more years, months, weeks, days, hours, minutes, seconds or the like.

According to the first example, each operation history indication of the operation history indications of the set of candidate sources 210, 220, 230 may specify a respective water consumption of a corresponding candidate source 210, 220, 230 of the set of candidate sources. The set of candidate sources 210, 220, 230 may be selected by the computing function 110 since they are included in the system 200 that the sensor 240 monitors for leakage or the like. For example, the respective water consumption may be related to the time period, such as a plurality of hours, prior to the first message.

According to the second example, each operation history indication of the operation history indications of the set of candidate sources 210, 220, 230 may specify a respective electric consumption of a corresponding candidate source 210, 220, 230 of the set of candidate sources. The set of candidate sources 210, 220, 230 may be selected by the computing function 110 since they are included in the system 200, or in a section or group thereof, that the sensor 240 monitors for release of the fuse of the system, or in particular that section or group. For example, the respective electrical consumption may be related to the time period, such as a plurality of minutes, prior to the first message.

The analysing A030 may comprise selecting the primary source 210, 310 that is associated with a respective operation history indication that is an extreme operation history indication among the operation history indications, such as a maximum or minimum operation history indication among the operation history indications.

The extreme operation history indication may be at least among the extreme operation history indications, possibly not necessarily the most extreme. For example, various further factors may be taken into account, such as relative severity of the candidate sources. For example, in case of a dripping or leakage, a location of the corresponding candidate source may be taken into account. If the location is in the basement of a house, it may be considered less severe than if the location is on the attic, in the kitchen, near the living room or the like.

In some examples, the extreme operation history indication may be determined, by the computing function 110, as a relative measure. That is, the relative measure may, for each candidate source, indicate said each candidate source's operation history indication relatively to a normal or common operation history indication, such as an average operation history indication during a measurement time period. It may be preferred that the measurement time period is in the same magnitude as, or greater than, the aforementioned time period prior to the first message.

According to the first example, the computing function 110 may select the primary source 210 that is associated with the respective water consumption that is a maximum water consumption among the water consumptions of the set of candidate sources 210, 220, 230.

Summarizing the first example, the computing function 110 receives the first message indicating leakage in the tap water system. Then the computing function 110 may fetch and analyse water consumption, i.e. operation history indications, during the time period prior to the first message for each candidate source. The candidate source associated with the greatest, or lowest, water consumption prior to the first message may be set as the primary source 210.

According to the second example, the computing function 110 may select the primary source 210 that is associated with the respective electrical consumption that is a maximum electrical consumption among the electrical consumptions of the set of candidate sources 210, 220, 230.

Summarizing the second example, the computing function 110 receives the first message indicating release of a fuse of the electrical system. Then the computing function 110 may fetch and analyse electrical consumption, i.e. operation history indications, during the time period prior to the first message for each candidate source. The candidate source associated with the greatest, or lowest, electrical consumption prior to the first message may be set as the primary source 210.

Action A040

The computing function 110 provides, to a person associated with the venue 100, a second message indicating the primary source 210, 310, thereby inviting the person to check whether the primary source 210, 310 is the cause of the malfunction or not.

When the primary source is the cause of the malfunction, further damage to the venue 100 may be avoided by that the user performs appropriate actions, such as closes water supply to the primary source, turns off electricity toward the primary source or the like. In many cases, these actions may even prevent that any damage at all is caused to the venue 100.

In this manner, the computing function 110 at least enables management of the risk factor.

As an example, the computing function 110 may send the second message to the client device 300. The second message may cause the client device to invite the user 310 to check the primary source 210, 320, e.g. by displaying a suitable text on the screen of the client device 300, by reading the message using text-to-speech synthesis or otherwise mediate the implication of the second message to the user 310.

According to the first example, the second message may indicate to the user 310 to check the primary source 210, e.g. one of the candidate sources that is connected to the tap water system that the sensor 240 monitors for leakage and/or water drip.

According to the second example, the second message may prompt the user 310 to check the primary source 210, e.g. one of the candidate sources that is included in the electrical system, or a particular section or group thereof that the fuse is associated with, said primary source being monitored by the sensor 240.

Action A050

The client device 300 may receive the second message. Reference is made to the description of action A040 above.

Action A060

The computing function 110 may detect that the user does not respond to the second message, preferably repeatedly. For example, the computing function 110 may detect that the user does not respond, by detecting that no confirmation message is received from the client device 300. The confirmation message may indicate to the computing function 110 that the primary source has been checked.

Action A070

This action is preferably performed subsequent to the detection A060 of no response to the second message.

In some examples, "no response" may include that the user selects ignore or the like when presented with, such as confronted to, or the like, the second message.

In further examples, "no response" may include that the user simply confirms the second message, but without appropriate handling to prevent the second message to appear again. Therefore, the second message will then, within shortly, appear again. The computing function 110 may provide, to the person, a third message indicating to the person how to act to decrease the risk factor and/or one or more actions to take to reduce or prevent damages to the venue 100.

The third message may indicate one or more of:

- to seal tap water system, e.g. in particular in the vicinity of the primary source;

- to increase ventilation, e.g. in particular in the vicinity of the primary source, or the like.

In this manner, the computing function may invite the user, such as a person in the venue 100, to change their behaviour.

Action A080

The client device 300 may receive the third message. Reference is made to action A070 for description of the third message.

In a further example, the computing function 110 may perform a combined analysis of two or more respective messages originating from a respective sensor device, which e.g. monitors the same system or a respective system. Such combined analysis may be performed in order to decrease the risk factor. Hence, a first sensor device may send, to the computing function, a first event message indicating duration of cooking, i.e. a stove has been active, such as turned on for cooking purposes, for the duration. Start and end points in time of the cooking may, also or alternatively, be indicated by the first event message.

Upon receiving the first event message, or after being notified about end of cooking, the computing function may fetch from a second sensor device a second event message indicating motion detected by the second sensor device at further location of the venue, such as a living room, home office or the like. In some examples, the second sensor may be a humidity sensor sensing humidity in a shower facility of the venue. In some examples, the second sensor device may send the second event message repeatedly and the computing function 110 may filter out the relevant data based on the first event message, i.e. the duration derived therefrom. In some examples, the first message may be exemplified by the first and second event messages.

When the computing function detects that the motion at said further location has been greater than a threshold value for motion during cooking, the computing function records an activity referred to as unattended cooking, or distracted from cooking.

After each recording of the activity, the computing function checks that a current number of registered activities referred to as e.g. unattended cooking, e.g. during a past time period, is above a further threshold value. The past time period may be a plurality of days or the like as deemed appropriate depending on the application.

When the further threshold value is exceeded by the current number of registered activities of unattended cooking, the computing function may send an alert message to the user. The alert message may invite the user(s) to change their behaviour by being present in the vicinity of the stove during cooking. As a result, the risk factor may be reduced upon conformance of user behaviour to the invitation provided by the alert message. In some examples, the second message of action A050 may be exemplified by the alert message.

In some embodiments, the computing function 110 may be said to perform a method for handling an error message, referred to as the first message above, wherein the error message may indicate that the malfunction is located within the system 200, 300.
