In an embodiment, a method determines one or more sources of carbon monoxide (CO) in a smart-home environment that includes a plurality of smart devices that have at least measurement and communication capabilities. The method includes measuring a level of CO in the smart-home environment to generate a CO measurement, and providing the CO measurement and one or more current characteristics of the smart-home environment, from one or more of the smart devices to an analyzing device. The method further includes evaluating, by the analyzing device and with the CO measurement and the current characteristics of the smart-home environment, a set of CO correlation scenarios that attribute generation of CO to a corresponding one of a set of specific sources, and selecting one or more of the specific sources as the most likely source of the CO, by aggregating results of the correlation scenarios.

Various arrangements for hazard detector event tracking is presented. A system may include a hazard detector and a computer server system. Indications of events that occurred at the hazard detector may be provided to and stored by a computer server system. A user interface application executed on a mobile device may receive the indications of events that occurred at the hazard detector. A timeline may be generated that graphically represents the indications of events. The generated timeline may be output for presentation via a display of the mobile device.

An electronic safe assembly includes a safe that has a door is hingedly thereto for storing valuables. A control circuit is coupled to the door and the control circuit stores a first code and a second code. A keyboard is coupled to the door for entering an alpha numeric code and the keyboard is electrically coupled to the control circuit. The control circuit receives a first input when the first code is entered with the keyboard and the control circuit receives a second input when the second code is entered into the keyboard. A locking unit is coupled to the door and the locking unit is electrically coupled to the control circuit. The locking unit is in communication with an extrinsic communication network to selectively contact emergency responders. The locking unit engages the safe when the door is closed thereby locking the door. The locking unit disengages the safe when either of the first or second codes is entered with the keyboard. Moreover, the locking unit transmits a distress call over the extrinsic communication network when the second code is entered to notify the emergency responders that the safe has been opened under duress.

Arrangements for controlling a climate control system are provided. A hazard detector of a group of smart devices may detect a carbon monoxide (CO) alarm condition at the hazard detector. The hazard detector may transmit, via a relatively low-power mesh communication network, an indication of the CO alarm condition to one or more other smart devices. A spokesman node of the relatively low-power wireless communication network may translate the indication of the CO alarm condition from a first wireless communication protocol to a second wireless communication protocol. The spokesman node may transmit the indication of the CO alarm condition to a system controller via a relatively high-power wireless communication network and the second wireless communication protocol. A system controller of the climate control system may transmit a signal to turn off at least part of the climate control system.

Various arrangements for assessing an installation of a smart home device are presented. An orientation of the smart home device may be analyzed to determine whether the orientation of the smart home device is unsuitable for one or more features of the smart home device to function properly. An indication of whether the orientation of the smart home device is unsuitable may be output, such as by the smart home device using voice or lighting.

In various embodiments, a smart home device is presented. The smart home device may include at least one sensor. The smart home device may include a speaker, a light, and a motion detection sensor that detects motion in an ambient environment of the smart home device. A processing system of the smart home device may be configured to select an illumination state based on a determined status. The processing system may cause the light to illuminate based on the selected illumination state. The processing system may determine a gesture has been performed in the ambient environment of the smart home device following the light being illuminated based on the selected illumination state. The processing system may output a detail of the status via the speaker corresponding to the illumination state in response to determining the gesture has been performed.

A method of deterring an armed assailant inside of a building which involves the steps of placing physically disabling devices inside a building occupied by people, placing video and audio devices inside a building, then connecting the devices to remote activation controllers, then recognizing an armed assailant by an occupant of the building with the ability to activate the physically disabling devices remotely, then activating the devices, then transmitting the audio and video media to law enforcement and building officials, then determining that the assault continues, then activating more physically disabling devices, then deactivating the devices.

A system and method providing for ascertaining the status of a user and escalating an alarm in the event the user is ascertained to be disposed in a dangerous condition. The of the invention attempts to contact the user at a predetermined check-in time, and notifies a pre-designated third-party which may be an emergency responder such as law enforcement or other emergency contact in the event that the user fails to respond to the check in request or signals that they are in danger using an escalate feature of the invention. The system operates autonomously to notify pre-designated emergency contacts or emergency responders in the case in which a user has been rendered unable to respond. The user may identify specific individuals with whom they plan to meet and the invention may also track the user's geo-location. The invention may also monitor biometric data of the user.

Communicating with law enforcement agencies using client devices that are associated with audio/video (A/V) recording and communication devices are provided. In one embodiments, a method for a client device for preventing redundant calls to an emergency call center is provided, the method comprising: receiving, at the client device, a notification, along with video footage associated with the notification, about an event generated by an A/V recording and communication device, the video footage captured by a camera of the A/V recording and communication device; receiving a request for contacting the emergency call center; informing one or more backend devices, in communication with the client device and a home security monitoring center that monitors a security system, of the received request to suppress a potential redundant call to the emergency call center from the home security monitoring center; and contacting the emergency call center.

Various methods and systems for smart home devices are presented. Such smart home devices may include one or more environmental sensors that are configured to detect the presence of one or more environmental conditions. Such smart home devices may include a light comprising a plurality of lighting elements. Such a light may be configured to illuminate using a plurality of colors and, possibly, a plurality of animation patterns. Such smart home devices may include a processing system configured to cause the light to illuminate using the plurality of colors and the plurality of animation patterns in response to a plurality of states of the smart home device.
