Did you follow this section of the tutorial?:

Finally add a persistence job so openHAB sends your item states to InfluxDB. Add all items or item groups you want to persist including fitting strategies to /etc/openhab2/persitence/influxdb.persist :

Strategies {
    everyMinute : "0 * * * * ?"
    everyHour   : "0 0 * * * ?"
    everyDay    : "0 0 0 * * ?"
}

Items {
    gHeatAct*, gHeatSet*, gHeatValve*   : strategy = everyChange, everyHour
    Presence_Phone                      : strategy = everyChange
}

Regarding strategies: a meaningful usage of these is dependent on the nature of your items and how often they are changed . everyChange is a good strategy with most items (like the power consumption of a washing machine), you might however additionally add a every... for items, that might not be changed for longer times (for example the preset temperature of a room). This is especially important, as Grafana will (by default) only draw graphs for times it has data for. If the preset temperature didn’t change for three hours, there will be no graph for the last three hours :wink:
