Hi Rob_in,
Thanks again for your response.
"So you had ioBroker, Grafana & InfluxDB working, right?" - Yes this is correct
"Then you threw that away and used a LoxBerry image?" - Yes, I erased the SD card and put Loxberry on instead.
"Then you installed ioBroker over the top of your LoxBerry? In which case... what's the story with InfluxDB? Does that come pre-installed on the LoxBerry image you used?" Yes I installed ioBroker on to the Loxberry, then I installed the plugin Influx/node/Grafana so no, it did not come preinstalled with the Loxberry image.
I have also installed the docker plug in which i understand is also necessary. The username/passwords for influx I am trying to use are the ones provided by the infl/nod/graf plug in on the Loxberry - "dbadmin" for both listening on port 8086 and I am assuming "loxberry" as the host? Anyone here done the same thing?
This is a big learning curve for me which is the object of the exercise so any thoughts/help/explanation is much appreciated!
