I am working on a flow that takes data from MQTT (mostly rtl_433 sensors) and converts the inputs to meaningful data that then is output to an Influx database. The tutorials I've read have gotten me started and after a couple questions here, I have most of the basic functionality to at least store appropriate data.
My next goal is to figure out retention policies such that I store the high fidelity data for a short time and then down sample to hourly averages for long term storage. I am currently working on the RPi onboard SD while learning, but I believe a better approach would be to have the high fidelity data stored on a USB flash drive and the long term data stored on my RAID server.
I have been reviewing a few tutorials, but not having experience managing databases, I'm not sure if I am on the right track. The following tutorial seems excellent when discussing setting up RP on the Influxdb side:
I don't know if what I am describing requires a separate database set up on the Windows server or if it can be handled by the RPi alone via SAMBA or similar. If someone could post a tutorial link or a high level recommendation on how to set things up I can continue my research.
I'm only 1 week in on NR, InfluxDB, and Grafana. These tools are absolutely amazing though!
