Home assistant add-on: elasticsearch server
I maintain this and other Home Assistant add-ons in my free time: keeping up with upstream changes, HA changes, and testing on real hardware takes a lot of time (and some money). I use around 5-10 of my >110 addons so regularly I install test machines (and purchase some test services such as vpn) that I don't use myself to troubleshoot and improve the addons
If this add-on saves you time or makes your setup easier, I would be very grateful for your support!

About
Elasticsearch is the distributed, RESTful search and analytics engine at the heart of the Elastic Stack. You can use Elasticsearch to store, search, and manage data for:
- Logs
- Metrics
- A search backend
- Application monitoring
- Endpoint security
- ... and more!
To learn more about Elasticsearch’s features and capabilities, see their product page .
Here, this addon is used to single node that can be called from other addons needing it.
Installation
The installation of this add-on is pretty straightforward and not different in comparison to installing any other add-on.

- Install this add-on.
- Click the
Savebutton to store your configuration. - Set the add-on options to your preferences
- Start the add-on.
- Check the logs of the add-on to see if everything went well.
Configuration
Elasticsearch runs as a single-node cluster accessible at http://homeassistant:9200. This addon has no web interface - it provides API endpoints for other applications.
API Endpoints
- HTTP API: Port 9200 for REST API calls
- Transport: Port 9300 for internal cluster communication
Options
No configuration options are available through the addon interface. Elasticsearch is pre-configured for single-node operation with:
- Memory allocation: 1GB heap (ES_JAVA_OPTS)
- Discovery type: single-node
- Memory lock: enabled
- Tini subreaper: enabled
Example Usage
Connect other applications to Elasticsearch using:
- URL:
http://homeassistant:9200 - No authentication required (local network only)
Integration Examples
