Variable Description

$v Measured value

$q Sensor type 1 = Temperature (°C), 3 = RH% (%), 5=CO2 (ppm)

$i Identicationnumberofthesensor

$r rssi-value (dBm)

$h Indication of the hours in the time indication of the measurement

$m Indication of the minutes in the time indication of the measurement

$s Indication of the seconds in the time indication of the measurement

$Y Indication of the year in the time indication of the measurement

$M Indication of the month in the time indication of the measurement

$D Indication of the day in the time indication of the measurement

$S Measurement time in seconds since 1-1-2000 UTC

$c Day of the week at the time of measurement (0=Sunday, 1=Monday...)

$a(len) Current running average value (len = Length in seconds)

$b(len) Current running minimum value (len = Length in seconds)

$e(len) Current running maximum (len = Length in seconds)

$p(dt) Previous value. If dt=0, then the previous measurement value is given,

otherwise, the interpolated value at the moment of dt seconds back in time is

given.

$p0 Latitude (degrees)

$p1 Longitude (degrees)

$p2 Altitude (m)

Except for the $S, all time indications are expressed in UTC under conside-

rationofthetimezoneosetindicationintheconguration.

The time indication $S is expressed in UTC.

The condition is structured like a logic expression. Following logical compa-

risonoperatorscanbeusedforthedenition:(<,<=,>,>=,<>,==and

!=), as well as the logical operators AND (&&), OR(||) and NOT(!). Also the

arithmetic operations +, -, *, / and % (modulo) can be used. Moreover the

expression can be organised with brackets „(„ and „)“.

Examples:

Expression Description

$v<10 is true as soon as the measurement goes below the value

10 .

$v<10 && $i=8297 is true as soon as the measurement for sensor 8297 goes

below the value 10.

($v<-10 || $v>10)&&$c==0 is true as soon as the measurement goes below the value -10

or above10 and the day of the week is a Sunday.
