We first experienced WiFire in our review of Traeger’s Timberline 850 grill, which we found to be an ideal addition to a smart home. Once connected to your home Wi-Fi network, you can download a recipe for the food you’re grilling using the Traeger app and pretty much walk away from the grill. It will automatically maintain the ideal temperature, adding wood pellets from its hopper as needed, with a probe continuously monitoring the internal temperature of the food itself.
