The update focuses on everyday usability: smoother navigation, more reliable updating, better lighting and ventilation controls, and more consistent humidity behavior.

Saunum has released a new software update for its Leil control system, focused on day-to-day usability. For owners already using Leil, it brings smoother navigation, more reliable updates, and better in-session control over fan and climate behavior.
The update also improves the update process itself. Control software only helps if it is easy to keep current, and Saunum says this release reduces friction in that maintenance cycle while refining lighting and ventilation menus.
Fan access while the screen is locked
Users can now run the fan even when the screen is locked, which removes a step when adjusting air circulation mid-session.
AutoLeil gets more stable session control
Saunum says the update improves AutoLeil precision and stability, with more consistent humidity behavior based on user settings. AutoLeil is Saunum’s automatic water-dosing accessory, designed to feed water to heater stones through the control system and help maintain a steadier sauna climate.
For broader context on Saunum’s current direction, see our earlier coverage of the Saunum Air Perfect US launch and the recent consolidation of the North American heater lineup, which retired the Air 10 in favor of the Air L for larger rooms.
How to install the update
Saunum says Leil owners can install this release directly from the remote panel. Both the control panel and power board need updates; the order does not matter. Exact steps can vary by installed software version.
The release is software only, with no new hardware. For official product and support resources, visit Saunum and Saunum US.
For a different control arrangement in a working venue, Adventuremine’s founder describes its underground sauna installation, including a local fan switch used by the ritual master.
