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.

A monitoring system that is configured to monitor a property includes a camera that is configured to capture video data of the property. The monitoring system further includes a microphone that is configured to capture audio data of the property. The monitoring system further includes a monitor control unit that is configured to access and analyze the video data. The monitor control unit is further configured to determine that an alarm condition does not exist at the property. The monitor control unit is further configured to access and analyze the audio data. The monitor control unit is further configured to override the determination that an alarm condition does not exist at the property. The monitor control unit is further configured to, based on overriding the determination that an alarm condition does not exist at the property, perform a monitoring system action.

Various arrangements for assessing an installation of a smart home device are presented. A video camera device may capture video indicative of a location of the smart home device. The video indicative of the location of the smart home device may be analyzed to determine whether the location of the smart home device prevents the smart home device from operating within specification. An indication may then be output indicative of whether the location of the smart home device prevents the smart home device from operating within specification.

System for displaying hazard events and adjusting hazard detector settings on a mobile device includes a user interface executed on the mobile device, a hazard detector, and a computer server system communicatively coupled to the mobile device and hazard detector. The hazard detector generates hazard events indicating detection of smoke or carbon monoxide. The hazard events are transmitted to the computer server system and then to the mobile device. User interface displays the hazard events in an event group. User interface receives an adjusted value for a setting of the hazard detector and transmits the adjusted value to the computer server system. The computer server system determines that the adjusted value corresponds to the hazard detector, receives a check-in event from the hazard detector, and transmits the adjusted value to the hazard detector in response to receiving the check-in event. The hazard detector applies the adjusted value to the setting.

A local maintenance monitoring unit is intended to be installed near an item of equipment, in order to make it possible to validate a task that is carried out by a maintenance technician on the item of equipment. The local maintenance monitoring unit is provided with short-range display or communication unit in order to transmit a check-value and a timestamp to a portable communication terminal with which the technician is equipped. It is thus possible to guarantee that the technician assigned for the task is actually located at the site of the maintenance task.

Hazard detector for providing a pre-alarm of a developing hazardous condition can include a detection module that detects a hazard level of smoke or carbon monoxide, a light source that generates light, a speaker that generates an audible sound, a horn that generates an audible alarm that a higher volume than the speaker, and a processing module. The processing module can receive the detected hazard level and compare it with the pre-alarm threshold and the emergency threshold. The processing module can determine that the hazard level is greater than the pre-alarm threshold and less than the emergency threshold and cause an audible pre-alarm speech to be generated via the speaker that warns of the developing hazardous condition.

A particular smart hazard detector may itself function as a guide during a process of installation of the same at an installation location. Additionally, the installation location of the particular smart hazard detector may play a central role in how various settings of the smart hazard detector are defined and adjusted over time.

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.

Provided are a portable security device having a rescue request function based on IoT which sprays tear gas to perform self-protection, automatically transmits a rescue request message and notifies a rescue requester of a response of a rescuer to the rescue request message to relieve the rescue requester, and a security system using the same.
