ThermoWorks Smoke X2 Long-Range Remote BBQ Alarm Thermometer
D1 Local Only — Speaks only to hardware you control.
The unplug test
There is no cloud for this device to be cut off from. The probe transmitter talks directly to its own handheld receiver over a dedicated 915 MHz radio link rated to 1.24 miles line-of-sight — the same link whether your house has internet or not. ThermoWorks explicitly states no WiFi add-on exists for this model, unlike its Signals product line.
Why this tier: Has a radio (FCC grants 2AI67-S2T transmitter and 2AI67-S2R receiver, 902.5-927 MHz proprietary spread-spectrum RF, not WiFi or Bluetooth) that speaks only point-to-point to a receiver the owner holds. ThermoWorks' own support documentation states no app, WiFi, or account exists for this model, and the same grantee separately files WiFi/Bluetooth grants for its connected line (Signals, BLUEDOT) — confirming Smoke X2 is deliberately the non-cloud product in the catalog, not an unfiled oversight.

Where to buy
Open questions
- Firmware update mechanism for the transmitter/receiver pair, and whether updates can be declined, was not established within budget.
- Exact current retail price varies by color/bundle and frequent promotions; $99-140 reflects the range observed across the manufacturer's own past pricing and independent retailers, not a single verified list price captured today.
Sources
Class A is primary (manual, FCC filing, teardown). Class B is corroborated community reporting. Class C is never sufficient alone.

Manufacturer support article: Smoke X2 uses 'an all-new RF wireless technology,' states 'A Wi-Fi enabled add-on is not available for Smoke X2' (unlike the original Smoke, which can add a WiFi gateway accessory), and confirms no account or internet connection is required for Smoke X2 to function; range up to 6,562 ft (1.24 mi) line-of-sight; 915 MHz RF; splash-proof IP66; up to 330 hours on AA batteries or USB-C powered. — accessed 2026-09-02 - A https://fccid.io/2AI67-S2T
FCC grant for ThermoWorks (grantee 2AI67) model S2T, the Smoke X2 transmitter: 902.5-927 MHz spread-spectrum Digital Transmission System under Part 15C, 1.4 mW output — a proprietary point-to-point RF link, not WiFi or Bluetooth. Sibling control: the same grantee (2AI67) separately holds WiFi/Bluetooth grants for its connected products (Signals, BLUEDOT 'Bluetooth thermometer'), confirming ThermoWorks files distinct grants when a product actually carries a cloud-capable radio, and Smoke X2's grant is for local-only RF instead. — accessed 2026-09-02
