The default InfluxDB configuration doesn’t enforce authentication. If you have installed InfluxDB on the same host where Home Assistant is running and haven’t made any configuration changes, add the following to your
# Example configuration.yaml entry influxdb:
You will still need to create a database named
home_assistant via InfluxDB’s web interface or command line. For instructions how to create a database check the InfluxDB documentation relevant to the version you have installed.
- host (Optional): IP address of your database host, e.g. 192.168.1.10. Defaults to
- port (Optional): Port to use. Defaults to 8086.
- username (Optional): The username of the database user. The user needs read/write privileges on the database.
- password (Optional): The password for the database user account.
- database (Optional): Name of the database to use. Defaults to
home_assistant. The database must already exist.
- ssl (Optional): Use https instead of http to connect. Defaults to false.
- verify_ssl (Optional): Verify SSL certificate for https request. Defaults to false.
- default_measurement (Optional): Measurement name to use when an entity doesn’t have a unit. Defaults to entity id.
- override_measurement (Optional): Measurement name to use instead of unit or default measurement. This will store all data points in a single measurement.
- exclude (Optional): Configure which components should be excluded from recording to InfluxDB.
- entities (Optional): The list of entity ids to be excluded from recording to InfluxDB.
- domains (Optional): The list of domains to be excluded from recording to InfluxDB.
- include (Optional): Configure which components should be included in recordings to InfluxDB. If set, all other entities will not be recorded to InfluxDB. Values set by the blacklist option will prevail.
- entities (Optional): The list of entity ids to be included from recordings to InfluxDB.
- domains (Optional): The list of domains to be included from recordings to InfluxDB.
- tags (Optional): Tags to mark the data.
Starting with 0.36 the InfluxDB component has a new schema to store values in the InfluxDB databases.
- There will no longer be any tags/fields named
- All numeric fields (int/float/bool) will be stored as float inside InfluxDB database.
- All string fields corresponding to state attributes will be renamed as
FIELDNAMEis the state attribute, to avoid type conflicts.
- All string fields corresponding to a state will be renamed as
- Fields named
valuewill always be stored as float.
- Fields named
statewill always be stored as string.
If you need to migrate your database, you may require to run the
influxdb_migrator script. Run the script after upgrade to 0.36 but before the first regular start of
hass version 0.36.
These are the steps the script will perform:
- Create a new database (called
DBNAME__old) to store old data.
- Copy data from
DBNAMEdatabase is now considered as the new database.
- For each measurement of
- Read all points from the current measurement (in groups of 1000 points by default) and convert them.
- Send group of points to
- Delete the
DBNAME__olddatabase if needed.
Example to run the script:
$ hass --script influxdb_migrator \ -H IP_INFLUXDB_HOST -u INFLUXDB_USERNAME -p INFLUXDB_PASSWORD \ -d INFLUXDB_DB_NAME
required arguments: -d dbname, --dbname dbname InfluxDB database name optional arguments: -h, --help show this help message and exit -H host, --host host InfluxDB host address -P port, --port port InfluxDB host port -u username, --username username InfluxDB username -p password, --password password InfluxDB password -s step, --step step How many points to migrate at the same time -o override_measurement, --override-measurement override_measurement Store all your points in the same measurement -D, --delete Delete old database
- If you run the script with only the
-hoption, you will get a help printout with a short explanation of the different options.
- The host option defaults to
- The port option defaults to
- You should be able to omit username and password if InfluxDB authentication is disabled, which it is by default.
- The step option defaults to
If you want to import all the recorded data from your recorder database you can use the data import script.
It will read all your state_change events from the database and add them as data-points to the InfluxDB.
You can specify the source database either by pointing the
--config option to the config directory which includes the default sqlite database or by giving a sqlalchemy connection URI with
The writing to InfluxDB is done in batches that can be changed with
You can control, which data is imported by using the commandline options
Both get a comma separated list of either entity-ids or domain names that are excluded from the import.
To test what gets imported you can use the
--simulate option, which disables the actual write to the InfluxDB instance.
This only writes the statistics how much points would be imported from which entity.
Example to run the script:
$ hass --script influxdb_import --config CONFIG_DIR \ -H IP_INFLUXDB_HOST -u INFLUXDB_USERNAME -p INFLUXDB_PASSWORD \ --dbname INFLUXDB_DB_NAME --exclude_domains automation,configurator
required arguments: -d dbname, --dbname dbname InfluxDB database name optional arguments: -h, --help show this help message and exit -c path_to_config_dir, --config path_to_config_dir Directory that contains the Home Assistant configuration --uri URI Connect to URI and import (if other than default sqlite) eg: mysql://localhost/homeassistant -H host, --host host InfluxDB host address -P port, --port port InfluxDB host port -u username, --username username InfluxDB username -p password, --password password InfluxDB password -s step, --step step How many points to import at the same time -t tags, --tags tags Comma separated list of tags (key:value) for all points -D default_measurement, --default-measurement default_measurement Store all your points in the same measurement -o override_measurement, --override-measurement override_measurement Store all your points in the same measurement -e exclude_entities, --exclude_entities exclude_entities Comma separated list of excluded entities -E exclude_domains, --exclude_domains exclude_domains Comma separated list of excluded domains -S, --simulate Do not write points but simulate preprocessing and print statistics
