InfluxDB (up to 0.8.x) Persistence

This service allows you to persist and query states using the InfluxDB time series database. The persisted values can be queried from within openHAB. There also are nice tools on the web for visualizing InfluxDB time series, such as Grafana.

There are two Influxdb persistence bundles which support different InfluxDB versions. This service, named influxdb08, supports InfluxDB up to version 0.8.x, and the influxdb service supports InfluxDB 0.9 and newer.

Database Structure

The states of an item are persisted in time series with names equal to the name of the item. All values are stored in a field called “value” using integers or doubles, OnOffType and OpenClosedType values are stored using 0 or 1. The times for the entries are calculated by InfluxDB.

An example entry for an item with the name “AmbientLight” would look like this:

time sequence_number value
1402243200072 79370001 6


First of all you have to setup and run an InfluxDB server up to version 0.8.x. This is very easy and you will find good documentation on it on the InfluxDB web site.

Then database and the user must be created. This can be done using the InfluxDB admin web interface. If you want to use the defaults, then create a database called openhab and a user with write access on the database called openhab. Choose a password and remember it.


This service can be configured in the file services/influxdb08.cfg.

Property Default Required Description
url No database URL
user openhab No name of the database user, e.g. openhab
password   Yes password of the database user that you chose in Prerequisites above
db openhab No name of the database

All item- and event-related configuration is defined in the file persistence/influxdb08.persist.
