Hi all,
I will migrate from pi3 to a proxmox server and was wondering how data is persisted and what options I have. At the moment I have an openDTU client which pushes data every 20s for 4 solar panels.
This together with my Shelly3EM generates nice solar production and usage graphs (shelly is updating like every second).
How is this data handled? I’d like to keep it at least for a year.
It would be okay to to only keep days production or usage for older data so no need for the full resolution, is this handled somehow?
I read somewhere that I can add InfluxDB but I first would like to understand what this would change. Also if I opt for InfluxDB is it advised as separate VM within my proxmox server or as an addon for my HA vm? Also HA has an internal DB aswell where comes this into play…
State and event data is stored for 10 days by default. See:
LTS (long term statistics) is down-sampled to hourly max, min, average and kept indefinitely. Only entities with a state class have LTS.
Using InfluxDB to store data is independent from home assistant. You can set your own retention policies and usually Grafana is used to visualise the data. Speedrun setup:
