Twins

The Twins endpoints enable creating, updating, and fetching one or more twins at a time. When receiving twins, there are also options to include relationships in the same response.

Operations

Relationships

Relationship endpoints enable creating, updating, and fetching relationship details.

Operations

Time Series

The Time Series endpoints are used for sending or receiving telemetry data. Once a Capability twin has been created that represents the time series, the telemetry associated with that twin can be created using either the twin's dtId (aka twinId) or externalId, a timestamp, and a value. Data is transmitted as an array so time series data can be batched and sent within a single request. Similarly, time series can be retreived for one or more Capability twins at a time using the twinId(s).

Operations

Insights

Insights are issues, opportunities, or knowledge that can help optimize or improve the performance of a building. They can be associated with any twin within Willow and are triggered in real-time by Skills that are running within Willow's Activate Technology and analyzing the incoming time series data.

Operations

Events

Events endpoints enable creating, updating, and deleting discrete occurrences such as Weather Forecast, Calendar events etc.

Operations

Tickets
