Characteristics

The table below contains a list of allowed characteristics. This will be extended over time. The philosophy has been to keep the app-adaptor API simple, so, for example, temperature is always in degrees Celsius and is a floating-point number. Apps and adaptors can easily make any conversions that are required for their own purposes.

Characteristic	Unit/Type	Description
temperature	Celcius/float	Temperature
humidity	Percent/float	Relative humidity
pressure	Bar/float	Atmospheric pressure
luminance	Lux/float	Luminance
battery	Percent/float	Battery status as a percentage of fully-charged
binary_sensor	-/string	Can take the values “on” and “off”
switch	-/string	Can take the values “on” and “off”
connected	-/Boolean	Indicates whether a device is currently connected
voltage	Volt/float	Voltage
current	Ampere/float	Current
power	Watt/float	Power
energy	KJ/float	Energy
buttons	-/dict	The states of a group of buttons in the form: { "1": "string", "2": "string" } The string can take the values "on" or "off". There may be one or more buttons.
