# Specific portlets

Specific portlets that are used for models of three device manufacturers:

* Engine event behavior for ATrack.
* Guard mode for Yatut.
* Harsh behavior for Suntech.

## engine\_control\_atrack

Special settings to set the engine event behavior for ATrack.

```json
{
  "power_voltage_high_level": 13800,
  "on_duration_seconds": 120,
  "power_voltage_low_level": 12800,
  "off_duration_seconds": 300
}
```

* `power_voltage_high_level` - int. Voltage in 0.001 volts for detecting engine ON state. Min=0, max=30000,\
  default=13800 mV.
* `on_duration_seconds` - int. Duration in seconds that must elapse before the engine state change accepted.\
  Min=0, max=600, default=1 second.
* `power_voltage_low_level` - int. Voltage in 0.001 volts for detecting engine OFF state. Min=0, max=30000,\
  default=12800 mV.
* `off_duration_seconds` - duration in seconds that must elapse before the engine state change accepted.\
  Min=0, max=600, default=5 seconds.

## guard\_mode\_yatut

Guard special settings for "Я ТУТ ПОИСК".

```json
{
  "motion_sensor_mode": "double_period",
  "motion_sensor_first_period": "23:00-07:00",
  "motion_sensor_second_period": "10:00-17:00",
  "motion_sensor_amplitude": 10,
  "motion_sensor_duration": 30,
  "motion_sensor_ignore_time": 50,
  "motion_sensor_double_check": false,
  "perimeter_mode": "once_triggering",
  "perimeter_diameter": 1
}
```

* `motion_sensor_mode` - [enum](/docs/navixy-api/user-api/backend-api.md#data-types). Can be "off" | "permanent" | "single\_period" | "double\_period". Default="off".
* `motion_sensor_first_period` - string time. Format=`HH:mm-HH:mm`, default="23:00-07:00" Required\
  for `motion_sensor_mode` in single\_period/double\_period.
* `motion_sensor_second_period` - string time. Format=`HH:mm-HH:mm`, default="10:00-17:00" Required\
  for `motion_sensor_mode` in double\_period.
* `motion_sensor_amplitude` - int. Min=1, max=255, default=5 Required for `motion_sensor_mode` != off.
* `motion_sensor_duration` - int. Min=1, max=255, default=5 seconds. Required for `motion_sensor_mode` != off.
* `motion_sensor_ignore_time` - int. Min=5, max=99, default=5 minutes. Required for `motion_sensor_mode` != off.
* `motion_sensor_double_check` - boolean. Default=`false`. Required for `motion_sensor_mode` != off.
* `perimeter_mode` - [enum](/docs/navixy-api/user-api/backend-api.md#data-types). Can be "off" | "once\_triggering" | "permanent" | "point\_displacement". Default="off".
* `perimeter_diameter` - int. Min=1, max=999, default=1 kilometer. Required for `perimeter_mode` != off.

## harsh\_behavior\_suntech

Harsh driving settings for Suntech.

```json
{
  "mode": "enable",
  "max_acceleration_force": 1.5,
  "max_braking_force": 0.05,
  "max_cornering_force": 3,
  "type": "harsh_behavior_suntech"
}
```

* `mode` - string. Can be "enable" | "disable".
* `max_acceleration_force` - double. Can be 0.05 – 3.0 g.
* `max_braking_force` - double. Can be 0.05 – 3.0 g.
* `max_cornering_force` - double. Can be 0.05 – 3.0 g.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://navixy.com/docs/navixy-api/user-api/backend-api/resources/tracking/tracker/settings/special/portlets.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
