using outdoor temp to program thermostat

[ecschnei]

What variable do I use to pull the outdoor temperature that shows up in my navigator to program my thermostat from?  I have a c4therm and no wunderground driver loaded but I thought there was a variable I could still use to adjust my setpoints based on outside temp.  Is this the case and where do I look?  The thermostat driver has 2 outdoor temp variables but it doesn't seem to be updating throughout the day.

Thanks in advance!

I use the weather underground driver to program off outside temp. I think it's the only way unless you add a temp sensor outside and run it to your inside tstat

Thank you Sir!

You don't specify what thermostat you have. But if you have the C4 thermostat, you can program using outside temperature, even if you don't have the outdoor sensor connected to it. The option has to be turned on.

How is the option turned on?
