Embodiments of the disclosure enable contextual user experiences to be provided. A computing system receives sensor data from an appliance associated with a first user account, and analyzes the sensor data to identify a product and one or more second user accounts associated with the product. The second user accounts are used to aggregate product data associated with the product, and the product data is used to generate catalog data associated with the product. The catalog data includes one or more portions associated with the second user accounts and is transmitted to a client device associated with the first user account to prompt a first user to enter into a transaction associated with the product. Each portion of the catalog data is selectable to facilitate the transaction between the first user and a respective second user associated with the second user accounts.

The present disclosure relates to a method for controlling for configuring a scenario mode for smart devices. The method include: acquiring a user account bound with a first smart device and a second smart device; identifying a predefined scenario mode template according to device information of the first smart device and the second smart device, wherein the predefined scenario template corresponds to a predefined scenario mode which associates at least one startup condition for the first smart device to trigger the scenario mode with at least one task to be performed by the second smart device when the scenario mode is triggered; bounding the predefined scenario mode template with the user account to enable the predefined scenario mode for the first smart device and the second smart device.

A controller controls a control target. The controller includes a time-series database that stores a record including data about the control target in chronological order, a data generator that generates data to be included in the record to enter the time-series database in every predetermined cycle, and a nonblocking queue included in a volatile main memory that sequentially stores the data generated by the data generator.

The present disclosure relates to a method and a server for controlling smart devices based on a predefined scenario mode. The method include: acquiring a status parameter collected by at least one first smart device bound to a user account; determining, according to the status parameter, whether to trigger a predefined scenario mode, the predefined scenario mode representing an operation mode for controlling actions of at least one second smart device bound to the user account according to the status parameter collected by the at least one first smart device; and sending a control instruction to the at least one second smart device, if it is determined to trigger the predefined scenario mode.

An arrangement for testing a control unit via a test environment, having a computer-based test management tool, wherein the test management tool is configured for model-based development and/or management of at least one test plan implemented as a data structure in order to test the control unit, and the test plan has at least one test and a start condition for initiating execution of the test plan; a computer-based test execution control tool, wherein the test execution control tool is configured to initiate execution of the test plan on the test environment when the start condition is met; and a computer-based database, wherein the database is configured to store the test plan implemented as a data structure and is also configured for shared, common access to the test plan by the test management tool and the test execution control tool.

A management system includes a first server and a second server. During ordinary operation, the first server apparatus is in a master state, and the second server apparatus is in a backup state. The second server apparatus belongs to a first group that receives data sent from the first server apparatus. The first server apparatus sends a first health signal to an address of the first group with a constant period. The second server apparatus switches from the backup state to the master state, based on the first health signal sent from the first server apparatus to the address of the first group.
