The recorder component needs an SQL database to store history. Which influxDB is not. If you want more performance with this try MariaDB.
See this guide on how to reduce your DB size: How to reduce your database size and extend the life of your SD card
You can store data in influxDB but the home assistant more info pop-ups are not able to use this (you still need the recorder DB). You have to supply your own Grafana graphs. I do this for very ‘chatty’ sensors and sensors I want to keep long term data for (2 years).
Yes this is correct.
This is not correct and I’d be interested to see where you got the idea it was. The history integration is for displaying data from the recorder DB. Like the logbook integration, which also uses the recorder database but displays in a different format.
If you still want to set up influxDB, watch Frenk’s tutorial on setting up influxDB and Grafana:
