What’s new
Version 4.27.0 · Updated October 23, 2026
This update brings new charging and battery controls, fixes for Smart Schedule, and clearer guidance throughout the app. • Set charging power and battery charge/discharge limits. • Use Smart Schedule with fixes for tasks that previously did not take effect. • Follow clearer device setup, connection, and firmware update instructions. • Updated wording and icons, plus bug fixes. Update your device firmware too: To use Battery Limits, Smart Schedule, and charging power settings correctly, use Sierro app 4.27.0 or later and firmware CL261017 or later. After updating the app, open Device Settings → Firmware Update and install the latest firmware available for your device. Updating the app does not automatically update device firmware. Note: After updating, the displayed battery level may temporarily show 30–39% before returning to normal. This is expected.
