Keep Umami. Erdi reads the API on a schedule and plots visitors, pageviews and visit duration under your events.
Visitors, pageviews and average session duration as daily series in the Traffic group. Cloud and a self-hosted instance both work — the host defaults to cloud.umami.is. There is no lag window.
An Umami API key, stored encrypted, plus the website ID. Erdi does not install a tracking script. This is a pull connector, not a webhook from Umami.
Realtime visitors, breakdowns by referrer or path, and session recordings. Those stay in Umami. Erdi only needs the daily line under the markers.
Set it up under Settings → Sources in your project.
