You should be able to wire up the remote sensor to the t-stat (if you aren't using it already) and use that temperature to update this free temp display driver.

You can use that driver with a network based unit and temp sensor as well.

Kevin,
Are there any CA devices that are hardwired and have temperature sensors? Even if it lasts several years, I'd rather eliminate as many attic crawls as possible!
