Overview
You can set rules for devices connected to the platform. If the conditions set in a rule are met, the platform triggers the corresponding action. Device linkage and data forwarding rules are available.
- Device linkage
When specific conditions are met, the platform triggers collaborative response of multiple devices to implement device linkage and intelligent control. Currently, IoTDA supports cloud rules and device rules. If you want to create a cloud rule and select Send notifications for Action in a rule, the platform will work with Huawei Cloud Simple Message Notification (SMN) to set and deliver topic notifications. If you want to create a device rule, the platform will deliver the rule to devices for unified management and execution.
- Data forwarding
IoT Device Access (IoTDA) can seamlessly forward data to other Huawei Cloud services and third-party applications, providing full-stack services for device data storage, computing, and analysis.
Cloud Service Access Authorization
The platform can connect to Huawei Cloud services. When creating a rule for connecting to Data Ingestion Service (DIS), Distributed Message Service (DMS) for Kafka, Object Storage Service (OBS), ROMA Connect, or SMN for the first time, you must authorize the platform to access the cloud service.
After the authorization, data on the platform can be forwarded to other Huawei Cloud services using data forwarding rules, or the platform can send commands to control devices using device linkage rules.
An agency named iotda_admin_trust is created on the Identity and Access Management (IAM) console and an administrator role is bound by default.
