Disclosed are various examples of an action framework for configuring a gateway to perform actions on the gateway itself or in conjunction with connected IoT devices. In some examples, a command is transmitted from a management service to a gateway device to permit a gateway client application to execute on the gateway device. A command to register an action in association with the gateway client application is also transmitted. The management service then commands the gateway device to perform the action, and receives an action results message with information about the action.

Gateway action framework

Disclosed are various examples of utilizing blockchain for tracking and auditing of systems and processes that involve Internet-of-Things (IoT) devices. A command to install an IoT event definition that defines an IoT event for a specified asset type is transmitted. IoT event data that indicates an IoT event has been triggered based on the IoT event definition is received. An IoT event block is recorded to a blockchain, the IoT event block comprising sensor data and an indication that at least one IoT device triggered the IoT event.

Internet of Things blockchain auditing

Disclosed are various examples of an action framework for configuring a gateway to perform actions on the gateway itself or in conjunction with connected IoT devices. In some embodiments, a gateway client is permitted on a gateway device using a gateway configuration received from a management service. A command callback function is registered in association the gateway client. An action message is received. The action message specifies an action corresponding to the command callback function. The gateway client using the action message. A command object for the gateway client is generated based on the action message. The command callback function is invoked, and the gateway client processes the command object to perform the action.

Disclosed are various examples for generating an Internet-of-Things (IoT) system topology. A user interface includes a graphical representation of components. A relationship between the plurality of components is determined based on user-defined connections between the components. IoT topology code is generated. The IoT topology code includes the relationship between the plurality of components and properties for individual ones of the components. The IoT topology code is converted to executable gateway instructions that enable a gateway device to communicate with an IoT device. The gateway instructions are transmitted to the gateway device.

Internet of Things system topology generation

Disclosed are various examples of utilizing blockchain for tracking and auditing of systems and processes that involve Internet-of-Things (IoT) devices. In one example, an IoT event definition is installed on a gateway. The IoT event definition includes a threshold value associated with an asset type. The gateway receives sensor data from an IoT device associated with the asset type. The gateway determines that the IoT device triggered an IoT event based on the sensor data and the IoT event definition. The sensor data indicates that the IoT device triggered the IoT event based on the threshold value. The gateway transmits, to a management service, a request to record an IoT event to a blockchain. The request includes the sensor data. A block that includes the sensor data is recorded to the blockchain.
