ThermoWorks Smoke X4 at a glance

What we like

  • Radio-frequency link that the maker rates up to 6,562 ft line-of-sight, with no pairing or Wi-Fi
  • Four channels for multiple cuts plus pit temperature, with ±1.8°F accuracy (probe dependent)
  • High and low alarms, and it pairs with ThermoWorks' Billows fan for hands-off pit control

Trade-offs

  • The probes are wired to the transmitter, so it isn't a leave-in wireless probe
  • No phone app or cloud graphing: you carry the remote receiver instead
  • The 6,562 ft figure is line-of-sight; walls and terrain will cut it down
Best for
Cooks who want rock-solid, no-Wi-Fi remote alarms for a long smoke.
Skip it if
You want phone alerts and cook graphs.
  • Channels: 4
  • Link: Radio frequency (not Wi-Fi or Bluetooth)
  • Accuracy: ±1.8°F (probe dependent)
