Hi, and thank you for reviewing the Traeger Timberline. Although any outdoor grill will take a bit longer to reach temp in colder weather, the Timberline is a fully insulated grill. Because of this, once the goal temperature has been achieved, it will be easier to maintain, even as the mercury level drops. However, we really don’t expect meat probes to properly measure inside of the barrel when using them as a test. Even regular oven thermometers are not designed to take into consideration the unique environment that is inside of a pellet grill, which the internal thermocouple is specifically designed to do. If you want to do an accuracy test, the easiest way is to simply turn on your Timberline from a cold start and compare the initial reading to the ambient air temperature. If it is within a reasonable range, then the grill is working correctly. If it's over 20 degrees off from the start, then we’ll want to look into it further. This includes checking the tip of the thermocouple for damaged, and verifying that the red protective cap was removed before the first use. But if this does not seem to be the case, or you want some help with the diagnosis, please call us at 1-800-TRAEGER, and one of our agents will go over everything with you to make sure that your Timberline is running exactly the way if should be, which also includes addressing any concerns that you have with the WiFi feature as well.
