Influxdb isn't working: "No extension service registered for influxdb"

Hi,

I have recently installed Influxdb and grafana with the inbuilt option in openhab (openhabian-config -> optional components -> influxDB+Grafana) on my raspberry pi 3 with openhab version 2.3.0-1.

I could not find any errors in the openhab log, so I decided to do the installation again. When the installation was finished, an error showed up in the openhab log:

2019-02-03 00:22:21.789 [ERROR] [nternal.extensions.ExtensionResource] - Exception while installing extension: No extension service registered for influxdb

It looks like everything is there to get it to work, but probably something is missing… What do I have to do to get this working?

influxdb.cfg

    user=openhab
    password=welcome
    db=openhab_db
    retentionPolicy=autogen
    url=http://192.168.1.49:8086

influxdb.persist

    Strategies {
        everyHour : "0 0 * * * ?"
        everyDay  : "0 0 0 * * ?"
        everyMinute  : "0 0 0 0 * ?"
        default = everyChange
    }

    Items {
        hueMotionSensorTemperature  : strategy = everyChange, everyMinute
        hueMotionSensorTemperature2  : strategy = everyChange, everyMinute
    }

Have you tried restarting OH?

sudo systemctl stop openhab2

sudo systemctl start openhab2

I have started the whole raspberry multiple times. Just restarted openhab only. No error message, but also no log rows of sending data to the influxdb.
It looks like the error message only apears at the installation of influxdb.

Try changing the influxdb.persist file this and see what happens.

Strategies {
    everyMinute : "0 * * * * ?"
    everyHour   : "0 0 * * * ?"
    everyDay    : "0 0 0 * * ?"
}
Items {
    hueMotionSensorTemperature      : strategy = everyChange, everyHour
    hueMotionSensorTemperature2    : strategy = everyChange, everyHour
}

Changed the influxdb.persist. Openhab says it is refreshing the file, but after some temperature changes, no logging rows or measurments to select in a grafana dashboard.
