Smart Home Carbon Monoxide Detector Guide

action.devices.types.CARBON_MONOXIDE_DETECTOR - Carbon monoxide detectors may report whether carbon monoxide is currently detected, whether the carbon monoxide level is high, and the current carbon monoxide level in parts per million.

This type indicates that the device gets the Carbon Monoxide Detector 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.

These traits are recommended, if applicable to your device. However, you are free to mix and match from all available traits to best match your existing product functionality.

Example device: Simple carbon monoxide detector

This section contains example intent payloads representing a common "Carbon Monoxide Detector" 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.
