Hi
Has anyone managed to get openhab 1.8.1 persistence influxdb 1.8.1 to work with influxdb 0.10.1.
I can get openhab to connect to the database and write measurements but no tag keys or tag values.
Cheers
Tony
As I tripped over this a few days ago, openHAB does not set any tags (even in influxdb 0.9.x) but stores the data and you can query the data with SELECT * FROM ‘itemname’; I didn’t set up grafana yet, but I think grafana will work that way.
EDIT: tested with grafana 2.6.0 and influxdb 0.9.6 -> works as expected. I will test the current influxdb version later, now time for a cup of coffee 
What is the best way to set this up under armhf? I tried a few tutorials but those are often not working…
for influxdb and grafana you should use the official instructions to install the software - https://influxdata.com/ and http://grafana.org/ - for Influx, the latest stable version would be https://s3.amazonaws.com/influxdb/influxdb_0.10.1-1_arm.deb (simply download and dpkg -i for debian-like distro)
for Grafana (I did not test this as I use amd64) there is a installscript, which seems to fit for Raspbian: curl -s https://packagecloud.io/install/repositories/grafana/stable/script.deb.sh | sudo bash should do the trick.
Bear in mind, that grafana will install it’s own webserver, listening at port 3000 as default.
I tried the following command SELECT * FROM ‘itemname’; and no data was shown. Is there anyway of seeing what openhab is writing is writing?
SHOW MEASUREMENTS is the command to see the list of persisted Data 
When I do the show measurements command I can see the list below, but no data within any of them.
cpu_temp
router_total_memory
router_used_memory
Here are the logs from openhab with influxdb trace level logging
2016-03-02 11:17:29.035 [TRACE] [i.i.InfluxDBPersistenceService] - Tried to get item from item class class org.openhab.core.library.items.NumberItem, state is 16240

Anyone know why it is not storing the value in influxdb? @Udo_Hartmann
Openhab can connect to influx and has added the measurements but there is no data within the measurements.
Here is my config

I experience the same with OpenHAB 1.8.3 using InfluxDB 1.0
It gives me 500 responses:
