Placeholders

Each Sensor supported by the firmware is responsible for delivering values to one or more placeholders. So whenever there are settings that relate to outputs from the Sensors, those placeholders may be used during configuration. At runtime the actual values will be used. In case of typos or using a placeholder whose Sensor is offline - no replacement will be done. The supported placeholders are as follows:

Placeholder	Sensor	Description
%TEMP%	Temperature/Humidity	Temperature in Celsius
%HUM%	Temperature/Humidity	Relative Humidity in %
%PRES%	Pressure	Pressure in hPa
%ALT%	Pressure	Altitude in meters (assuming 1013 hPa sea level pressure)
%CO2%	CO2	CO2 Concentration in PPM
%PM25%	Dust	PM 2.5 Level in umg/m3
%PM10%	Dust	PM 10 Level in umg/m3
%LUX%	Light	Lightness level in LUX
