Conditions
The condition is a logical expression that is evaluated within the context of
the received measurement. The value of the measurement and its associa-
ted attributes will be evaluated as variables.
The following variables are available:
Variable Description
$v Measurement value
$q sensor type 1 = temperature (°C), 3 = RV% (%), 5 = CO2 (ppm)
$i sensor
$r rssi value (dBm)
$h measurement time in hour
$m measurement time in minutes
$s measurement time in seconds
$Y measurement time the year
$M measurement time the month
$D measurement time the day
$S measurement time in seconds since 1-1-2000 UTC
$c measurement day of the week (0=sunday, 1=mondat, etc...)
$a(len) running average (len = length in seconds)
$b(len) running minimum (len = length in seconds)
$e(len) 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.
All time variables, except time $ S are UTC plus the time zone offset, is
given in the Time server setting page. The time variables $ S is in UTC.
The condition is structured like a logic expression. Following logical compa-
rison operators can be used for the denition: (<, <=, >, > =, <>, == and
!=), as well as the logical operators AND (&&), OR (| |), and NOT (!). Also
the arithmetic operations +, -, *, /, and% (modulo) can be used. Moreover
the expresion can be organised via the brackets “ „ and „ “.
