# Retrieve latest sensor readings for multiple trackers

Call batch\_list with a list of tracker IDs to retrieve latest sensor readings. Get all trackers first, then filter for those with data

## Question

Is it possible to get a list of tracker IDs that have sensor data?

## Answer

You can retrieve latest readings using:

`tracker/sensor/readings/batch_list`

Note: this method works with a **list of tracker IDs that you provide** — it doesn't automatically return "all trackers that have sensor data".

To build a list of trackers that have readings:

1. Get the list of all trackers in the account.
2. Call `batch_list` for that list.
3. Filter out trackers with no readings.

# 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 by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://navixy.com/docs/qna/apis/retrieve-latest-sensor-readings-for-multiple-trackers.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
