Boolean

bool()

boolean()

contains('The quick brown fox jumped over the lazy dog', 'brown') - tests parameter 1 for parameter 2 as any word (case sensitive)

endsWith('The quick brown fox jumped over the lazy dog', 'brown') - tests parameter 1 for parameter 2 as the last word (case sensitive)

eq('123', '321') - checks if both parameters are equal. This will return false

ge(1000, 900) - Checks if parameter 1 is greater than or equal to parameter 2. This will return true.

gt(1000, 900) - Checks if parameter 1 is greater than parameter 2. This will return true.

isEmpty()

le(1000, 900) - Checks if parameter 1 is less than or equal to parameter 2. This will return false.

lt(1000, 900) - Checks if parameter 1 is less than parameter 2. This will return false.

not()

startsWith('The quick brown fox jumped over the lazy dog', 'brown') - tests parameter 1 for parameter 2 as the first word (case sensitive)

Decimal

avg([Device 1:temperature], [Device2:temperature], [Device 3:temperature]) - Gives you the average temperature of the three devices

ceil()

ceiling()

celsius([Sensor:temperature]) - Gives the temperature reading in celsius

decimal()

dewPoint([Sensor:temperature], [Sensor:humidity]) - Gives you the dewpoint temperature for that sensor

fahrenheit([Sensor:temperature]) - Gives the temperature reading in fahrenheit

float()

floor()

max([Front Door :temperature], [Back Door :temperature], [test sensor :temperature]) - Returns the max value of selected devices

median([Front Door :temperature], [Back Door :temperature], [test sensor :temperature]) - Returns the median value of selected devices

min([Front Door :temperature], [Back Door :temperature], [test sensor :temperature]) - Returns the min value of selected devices

number()

power(10,3) - Evaluates parameter 1 to the parameter 2 power (e.g. 10*10*10 = 1000)

round(75.6548, 1) - Rounds a decimal based on value of parameter 2. This will return 75.7

sqr(100) - Gives the squared value of the parameter. This returns 10000

sqrt(100) - Gives the square root of the parameter. This returns 10.0

stdev()

sum(1,5,6) - Adds all the values

variance()

least()

most()

previousValue()

Integers

age([Device:switch) - Gives you the time in MS the device has been on

count([Device 1:contact], [Device 2:contact], [Device 3:contact], [Device 4:contact]) - Returns the number of open doors

int()

newer()

older()

previousAge()

String

concat('abc', 'def') - Returns the two strings as 'abcdef'

format("%.2f", celsius([Sensor:temperature])) - Returns the Celsius temperature formatted with two decimals

left('abcdef', 2) - Returns the first two characters in the string value or variable (ex: 'ab')

lower("HELLO, WORLD") - Returns as "hello, world"

mid('abcdef', 2, 3) - Skips the first 2 characters and returns the next 3

replace()

right('abcdef', 2) - Returns the last two characters in the string value or variable (ex: 'ef')

sprintf()

string()

substring("abcdef", 2, 4) - Skips the first 2 characters and returns the next 4

text()

title("hello, world") - Returns as "Hello, World"

upper("hello, world") - Returns as "HELLO, WORLD"

Time
