How to Update Your Smoke Gateway’s Firmware

Whenever your Smoke Gateway’s firmware needs to be updated, you’ll receive a notification in the ThermoWorks app. Here’s how the update is accomplished:

Smoke Gateway Power Button

1. Press your Smoke Gateway’s power button three times with a short, half-second delay between each press.

2. Once the firmware has updated, your Smoke Gateway’s LED will flash blue 5 times (one second apart) followed by a 15-second pause with no flashes.

3. Press Next in the ThermoWorks app when the LED is no longer flashing blue.

What to Do if the Update Doesn’t Work

If your Smoke Gateway doesn’t update the first time you try… don’t worry. The timing was likely off when you pressed the power button three times. Just try again using a slightly different time-delay between the button presses.

Note: You do not need to turn your Smoke Gateway off before retrying the firmware update!
