ööreiimi

Ööreiimi is an Estonian term describing a night-oriented operating regime or configuration that applies during nighttime hours. The word is formed from öö (night) and režiim (mode), with öörežiimi functioning as the genitive form used in phrases like “ööreiimi seadistused.” In practice, the concept refers to a set of parameters that switch or adjust devices, services, or systems to a calmer, lower-intensity state at night.

In consumer electronics and software, ööreiimi commonly includes features such as reduced screen brightness and blue-light filtering, throttling of nonessential background processes, scheduled data synchronization, and Do Not Disturb or silent operation. The aim is to conserve energy, minimize notifications, and reduce disruption during typical sleep hours. For networked systems and smart-home ecosystems, night regimes may entail scheduled maintenance windows, limited data collection, and energy-saving modes.

Activation can be time-based (automatic switching at predefined hours) or tied to astronomical times (sunset/sunrise). Users may often override or customize parameters to fit personal routines. Considerations for implementation include potential effects on timely updates, backups, or alerts, as well as accessibility and usability concerns for people who rely on certain notifications or higher accessibility brightness levels.

There is no single universal standard for ööreiimi; the term is used variably across devices and ecosystems. It serves as a descriptive label for the broader concept of night-time operating modes designed to reduce energy use and disturbance.
