I would prefer 100 series and 1400 days data retention for my home made arduino meteo station. I am interested to see the home climate changes over seasons.
We are working on managed VictoriaMetrics, which will have free tier suitable for your needs. In the mean time you can try storing measurements from your meteo station in a single-node VictoriaMetrics, which can run in resource constrained environments such as Raspberry PI. It supports various data ingestion protocols (CSV, Prometheus, InfluxDB, Graphite, OpenTSDB, JSON), so it is likely you'll find the best one for your case [1].
On a read side VictoriaMetrics is compatible with Prometheus datasource for Grafana [2].
