Goodmorning everyone. I need help. I do not sleep at night anymore … 
I have OH2 with persistence Influxdb and Grafana. Nothing works. The DB is not written and I also receive an error from Grafana. Ah, everything is on windows …
My file influxdb.cfg is this:
# The database URL, e.g. http://127.0.0.1:8086 or https://127.0.0.1:8084 .
url=http://127.0.0.1:8086
# The name of the database user, e.g. openhab.
# Defaults to: openhab
user=merk
# The password of the database user.
password=merk
# The name of the database, e.g. openhab.
# Defaults to: openhab
db=MarcoOpenhab
retentionPolicy=autogen
My file influxdb.persist is this:
Strategies {
everyMinute : "0 * * * * ?"
everyHour : "0 0 * * * ?"
everyDay : "0 0 0 * * ?"
}
Items {
TemperaturaOra_12715* : strategy = everyChange
}
The declaration of this item in file myhome.items is most simple as possible:
Number TemperaturaOra_12715 "12715 Temperatura Corrente"
Grafana reply :" InfluxDB Error: error parsing query: found ON, expected identifier at line 1, char 25 "
Openhab log is:
