Smart Home Curtain Guide

action.devices.types.CURTAIN - Curtains can be opened and closed, potentially in more than one direction. For example, curtains with two sections may open either to the left or to the right.

This type indicates that the device gets the Curtain icon and some related synonyms and aliases.

Device capabilities

Refer to the corresponding trait documentation for implementation details, such as attributes and states that your service should support, and how to build EXECUTE and QUERY responses.

Required traits

These traits and commands are required, if applicable to your device. If your device does not support these traits, enter the error code of functionNotSupported in a QUERY or EXECUTE response. See Errors and exceptions for more info.

Quality requirements

  • Latency: must be less than or equal to 2500ms.
  • Reliability: must be more than or equal to 97%.

Example device: Simple curtain

This section contains example intent payloads representing a common "Curtain" based on the device type and traits above. If you add or remove traits in your implementation, modify your responses accordingly to reflect those changes.
