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.

I would use a pseudo instead of a property, but it's just personal preference for being able to see exactly what is happening.

in the temp sensor ON script I would check the state of the "alert condition for fridge" pseudo. if it's not on I would turn it on, and if the temp is below the alert point I would check to see if it's off, and if not I would turn it off.

I would create a global script that checks the state of the alert condition pseudo, and if it's on send the message.

in the ON script of the alert condition pseudo I would do an execute script "the global script from above" in 6 minutes
and in the off script I would remove unit events for that same script name.

So if you're above the temp it turns on the alert pseudo and creates the event to run that script. 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.

Thanks,
