Scene activated - Grafana overview

Hi, I am struggling to find out when I activated scenes in home assistant. Every night I manually activate a scene and wanted to make a graph in grafana to see when I did so (time table).

But I cannot find any way to do this. Is the activation time even recorded somehwere?

Scenes have no state nor history, so are not recorded in influxDB (which I assume is the grafana backend), either.

Yes influxdb. Ok thanks for replying. I will include a helper from now on. Should be helpfull to have an activate history on scenes (for me).
