In April of last year, the Home Assistant Core database underwent a major transformation. This upgrade resulted in a significant reduction in database size, cutting it by 10-35% for most users, and considerably improved data load speeds on the Home Assistant Dashboard. With the 2022.6 release, Home Assistant Core is set to enhance these improvements further, promising an even leaner and faster database.

Significant Database Reduction

The latest update is expected to reduce the database size by an additional 25-40% for most installations. This reduction will occur gradually, as new data is recorded and old data is purged, rather than instantaneously. The substantial reduction is achieved by storing only references instead of entire event data, provided the same data already exists in the database.

Prolonging the Life of Your SD Card

The update also reduces disk writes, which is especially beneficial for those running Home Assistant OS on a Raspberry Pi. This reduction in disk writes can potentially extend the lifespan of your SD cards. Additionally, you will notice that the history of an entity and the logbook will load faster.

Home Assistant Core 2022.6 Overview

In conclusion, Home Assistant 2022.6 focuses on critical behind-the-scenes tweaks that enhance the overall user experience. These improvements are comparable to upgrading the processor and memory of your daily driver. While you might not see the changes, you will certainly feel the difference. Best of all, these updates come at no extra cost, making your Home Assistant experience smoother and more enjoyable.
