As a “clean start”, I have installed HomeAssistant as a VirtualBox client. Then InfluxDB and finally Grafana.
I think InfluxDB is reading/storing my ESPHome sensor correctly because I can use the InfluxDB “Explore” to view it. However, I seem to have trouble getting the Add Data Source to complete. When I select “Save & Test” it reports “Invalid URL”. I note from various tutorials that the URL may be “http://a0d7b954-influxdb:8086” but I can not edit the Garfana URL field?
I note somewhere, that only a Grafana Admin can create a Data Source. Is this a likely reason?
