Looks like ThermoWorks is having a limited-time 50% off sale on their Smoke units. While it is not WIFI-enabled, the Smoke comes with a paired receiver that is claimed to work up to 300’ away. If you need a 2-channel, wired-probe remote thermometer setup, this is a great price for a quality unit; $49.50.
