# Inputs and outputs

- [Input triggering](https://navixy.com/docs/user/guide/events-and-notifications/inputs-and-outputs/input-triggering.md): Receive alerts when a discrete GPS device input changes state, such as a door sensor opening, ignition turning on, or an emergency button being pressed.
- [Output triggering](https://navixy.com/docs/user/guide/events-and-notifications/inputs-and-outputs/output-triggering.md): Monitor GPS device output state changes such as engine block activation or alarm engagement. Receive alerts whenever a configured output switches on or off.
- [Parameter in range](https://navixy.com/docs/user/guide/events-and-notifications/inputs-and-outputs/parameter-in-range.md): Alert when a GPS device sensor enters or exits a defined value range. Supports measurement sensors and virtual sensors, with a configurable accuracy buffer.
- [State field value](https://navixy.com/docs/user/guide/events-and-notifications/inputs-and-outputs/state-field-value.md): Get notified when a specific device state field reaches an expected value, such as a door opening, DTC code appearing, or a driver key being recognized.
