Triggers decide when home automation runs — fire on sensor thresholds, schedules, button presses, or incoming webhooks to start an action.

Executors are the action nodes in a home automation workflow — send alerts, run scripts, call webhooks, and control devices when a trigger fires.

Filter out dropouts and invalid readings by ignoring any sensor value below a minimum you set before it's stored.

Throttle noisy or chatty sensors — rate-limit readings so a value is only logged once per set time interval.

Smooth noisy sensor data by ignoring small changes — only log a new reading when the value moves more than a set amount.
