Internet of Things (IoT) & Embedded Systems Architecture
Home Assistant Core Optimization
Home Assistant runs local automation across hundreds of integrations, and performance depends on database choice, recorder settings, and integration efficiency. A hub that starts fast and stays responsive is mostly a matter of pruning history and avoiding polling storms. The same discipline applies to small business installations.
Príomhphointí
- Move the recorder database to Postgres or a tuned SQLite instance for larger installs.
- Exclude noisy entities from history and keep retention short.
- Prefer local push integrations over cloud polling where available.
- Watch startup time as a signal of integration health.
- Run on reliable storage, since SD cards fail under database writes.
- Keep backups off-device and test restores.
- Use automations with explicit triggers rather than frequent template polling.
- Update integrations in batches and watch logs for regressions.
Ceisteanna coitianta
Why is my Home Assistant slow?
Usually database growth, polling integrations, or underpowered storage.
Should I use SQLite or Postgres?
SQLite is fine for small installs. Postgres scales better with history and many entities.
How do I reduce history size?
Exclude noisy entities and shorten retention.
Is a Raspberry Pi enough?
For small setups yes, but use SSD storage and expect limits as integrations grow.
