Why is RFX’s signal superior to Bluetooth?

Bluetooth uses a 2.4 GHz frequency, leading to higher attenuation through obstacles. RFX’s 433 MHz technology penetrates barriers like metal and walls more effectively, ensuring a reliable connection everywhere.

Can RFX MEAT transmit from inside metal cookers?

Our wireless probes operate effectively inside smokers, grills, sous vide setups, and even inside pressure cookers. Ensure the probe is correctly positioned up to its immersion line for optimal performance — and avoid the microwave!

Is RFX GATEWAY waterproof for outdoor use?

Yes! It’s rated IP66 for water resistance, making it safe to use outdoors without additional protection.

Can you use the ThermoWorks app without Wi-Fi access?

Capture temperature data anywhere via the app, as long as your RFX GATEWAY is Wi-Fi connected and your phone has internet access, either through Wi-Fi or data.

Can I add extra probes later?

Yes! Each RFX GATEWAY handles 50+ probes. To add more to your account, launch the app, connect your new probe, and get cooking.
