Unable to create a property in a RFXCOM Unit

[Hendrik van Eeden]

Hi James,

This is the script that I am using.  It is the ON script for the temperature sensor.

if (future value of (thisUnit)) < 6 then
	Set Unit Property "timer" to 0 in unit (thisUnit)
else
	if (Get Unit Property "timer" from unit (thisUnit)) is equal to 0 then
		Set Unit Property "timer" to (current date) in unit (thisUnit)
	else
		if (current date) - (Get Unit Property "timer" from unit (thisUnit)) > 50 * minutes then
			set description of the "Reporting Unit" to thisUnit
			turnon "Reporting Unit"
		end if
	end if
end if

The reporting unit sends SMS's for this condition and others.
It seems to work OK.  Why do you suggest a pseudo unit over a property? Are there advantage/disadvantages pseudo over property?

Henk

However the freezer goes into a defrost mode for about 45 minute at which time the temperature reaches about 36 °F, the temperature then returns to normal.  So, I only want an SMS when the temperature stays above 6 °F for longer than 45 minutes.

If the temp goes right back down again then the alert pseudo will be off when the script runs and nothing happens, but if the script finds the pseudo still on after whatever the time is then send the alert.
