Field Name	Type	Description
value_celsius	double	The value in celsius, always! Use device attributes if the device 'thinks' in a different unit but always communicate in celsius.

AudioLevel

Represents an audio signal level for either input or output devices. Typically if fine grained control of either gain or muted is required then a FieldMask should describe this.

Field Name	Type	Description
gain	float	The current gain, typically as a percentage unless documented in the AudioLevel usage.
gain_tween	smartcore.types.Tween	How the gain changes or should change over time. On write only duration should be set.
target_gain	float	Read-only, the target value for the gain during a transition
muted	bool	If the audio level muted.

AudioLevelChange

A change to the audio level

Field Name	Type	Description
name	string	The name of the device that is the source of the change
change_time	google.protobuf.Timestamp	When the change was applied
level	AudioLevel	The new state for the change

TemperatureUnit

Possible temperature units for physical bodies.

Name	Number	Description
TEMPERATURE_UNIT_UNSPECIFIED	0
CELSIUS	1
FAHRENHEIT	2
KELVIN	3

MuteSupport

What is the level of mute support that the speaker provides

Name	Number	Description
MUTE_SUPPORT_UNSPECIFIED	0
MUTE_NATIVE	1	The speaker natively supports mute
MUTE_EMULATED	2	Muting is emulated, typically by setting the gain to 0
