Add temperature (internal and external) conditions to scheduling

It would be nice to have be able to schedule an activity based on external and/or internal temperature.  For example, I currently have a schedule set to "Start HVAC when I am at work at 5:23pm".  However, I'd like to be able to set another condition, such as "Start HVAC when I am at work at 5:23pm if the external temperature is less than 50 degrees" or "higher than 80 degrees".  Perhaps even make a temperature variance variable such as "Start HVAC when I am at work at 5:23pm if the difference between internal and external temperature is greater than 20 degrees".  Since you already pull internal and external temps, maybe these would be a relatively simple conditions to add to your already great scheduling.  Thank you for considering.
