It is not independently GFI protected, but most/all outdoor outlets that it would plug into are required to be. Both outlets are controlled as one, i.e. if you turn off the outlet, they both turn off. For the current and temperature, it claims 32-104 Fahrenheit, but mine worked great yesterday and today with temperatures below 32 degrees (29 with a light drizzle and 24 with snow/sleet/rain, respectively) and has continued to worked fine.
