Following variables are available:
Variable Description
$v Measured value
$q
Sensor type 1 = Temperature (°C), 3 = RH% (%), 5=CO2 (ppm)
$i
Identification 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.
Except for the $S, all time indications are expressed in UTC under conside-
ration of the time zone offset indication in the configuration.
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 definition: (<, <=, >, >=, <>, == 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
$v<10
$v<10 && $i=8297
($v<-10 || $v>10)&&$c==0
The HTTP-report, the e-mail report and the subject line for the e-mail are
text fields that can be fitted with variables. The value of a variable will be
replaced by text when the message text is set up.
Description
