While at higher elevations, attempting to cook with Joule at higher temperatures may result in that Joule either will not start, reaching that temperature takes a long time, or the target temperature is never reached. In general, it's recommended to insulate the cook setup as best as possible to reduce heat dissipation for high temp cooks, especially at higher elevations.
Joule also has a built-in atmospheric pressure sensor designed to safeguard the maximum allowable temperature to prevent your water from reaching boiling point. So, as the boiling point of water drops, so does the maximum temperature Joule can operate.
In addition, when cooking with Joule at elevation, you may also need to manually modify the temperature and timing of your cooks to account for this.
