Smart Home Air Conditioning Unit Guide

Device TYPE

action.devices.types.AC_UNIT Air conditioning units are similar to thermostats, but do not support heating and may not support setting temperature targets, but rather rely on modes, toggles, and fan speed settings (for example, high and low).

This type indicates that the device gets the appropriate icon and some AC unit synonyms/aliases.

These are our recommendations for traits on this type of device, however you are free to mix and match from all available traits to best match your existing product functionality.

Please see each individual trait document for implementation details like required attributes, EXECUTE and QUERY.

Sample SYNC Request and Response

This is an example using the device type and traits above. It is intended to give an idea of how to build a SYNC response. If you add or remove traits, this will need to be modified to reflect those changes.
