Inspect running simulations and clear backed-up logs. Simulations auto-stop after 24h.
These tables grow every tick while a simulation runs. Clearing runs in batches in the background and can take a while for very large tables.
Device History
Per-tick sensor/tank readings used for charts. Usually the biggest table.
Event Log
Device start/stop/error events shown in the live log.
Alerts
Warning / error / info alerts raised during simulation.
