So I've been waiting patiently for something equivalent to Home Assistant but for QS and you pop up often. You're probably most expert to say what progress is being made for an integrated QS platform whereby you plop in a new integration and, even if there are a few manual steps (exporting, running a local software tool, etc.) you easily can import, slice on, and chart your data in a time series DB (similar to how with InfluxDB and Grafana you can do with Home Assistant). There were a few open source tools out there on GitHub but the ones I found were dated or didn't seem to have much love or enough of an audience to support them.
OH! I just saw you are the author of HPI which I have starred - it certainly was as close as I found but I pined for more evaluating it about half a year ago. How is progress? What other wise words can you lend?
