Assets Explorer

Learn how to use Assets Explorer in Perspio to review asset signals from connected devices. This guide explains Current State vs History, selecting assets or groups, adding/removing signals, using Grid and Chart views, setting time ranges, and exporting results to CSV or Excel.

Overview

The Explorer → Assets tool lets you query and review asset signals sourced from the devices connected to those assets. It is designed for operational troubleshooting, validation, and analysis—so you can confirm what Perspio is receiving (and when), before you act on it in reports, workflows, or customer communications.

Explorer → Assets is important because it helps you:

  • Validate the latest known state of an asset (Current State)

  • Investigate how a signal changed over time (History)

  • Troubleshoot device reporting issues (missing data, stale values, unexpected spikes)

  • Confirm the correct signals exist before using them in Workflows Conditions and Actions

Current State vs History: what’s the difference?

Current State

Current State shows a snapshot of the most recent value Perspio has for each selected signal, per selected asset.
Use it to quickly answer: “What is the value right now (or last known)?”

History

History shows time-based records for selected signals, allowing you to review changes across a selected time range (e.g., last X days).
Use it to answer: “When did it change, how often, and what pattern does it follow?”

Where to find it

  1. Open Explorer from the left navigation.

  2. Select Assets.

Once inside Explorer → Assets, you will work across two main areas:

  • Left panel: mode selection, asset selection, signal selection, and query controls

  • Main panel: results table and chart, plus export controls

Screen layout and controls

Left panel: search configuration

The left panel contains all controls needed to build your query:

1) Search Mode

A toggle at the top allows you to select:

  • Current State

  • History

 

2) Assets selector

The Assets section lets you choose which assets you want to query.

Controls

  • Asset dropdown: select an asset (example shown: “[133] GO9: Odi’s VW”).

  • Selected asset chips: appear beneath the dropdown; each chip includes an X to remove the asset from the query.

Usability

  • Keep the selection tight when troubleshooting (1–3 assets) so results are easier to interpret.

  • Add more assets when comparing behaviour across multiple assets.

Note: In the expanded selector, you can toggle between Assets and Groups and use the search field to quickly locate the right target.

3) Signals list

The Signals (Asset Details and Telemetry) section defines what fields you want to retrieve for the selected assets.

Controls

  • Each selected signal appears as a row (examples shown: Asset Name, Perspio Id, Active, Engine Coolant Temp).

  • Each signal row includes an X control to remove that signal.

  • + Add Signal button to include additional signals in the query.

Usability

  • Start with identity signals (Asset Name, IDs) so you can always confirm the record context.

  • Add only the telemetry/config signals needed for the investigation (this keeps tables and charts readable).

4) Query controls (bottom)

At the bottom of the panel you typically have two action buttons:

  • Reset button (red, undo icon): clears the current configuration and returns the panel to a baseline state.

  • Search / Run button (blue, magnifying glass icon): executes the query using the current selections.

Main panel: results and export

The main panel displays results for your selected assets and signals.

1) Search assets (results filter)

At the top of the results area, there is a Search assets field.
Use it to filter the displayed results quickly when you have multiple assets or many signals.

2) Results table (Current State)

In Current State, results are shown as a table with columns such as:

  • Asset ID

  • Signal

  • Current Value

This view is best for quick validation of the latest value Perspio has recorded.

3) Export controls

On the top-right of the results area:

  • Export button: opens export format options.

  • Settings (gear) button: typically used for view/table preferences (tenant-dependent).

Using Current State mode

What Current State is best for

  • Confirming whether a signal is currently present and populated

  • Checking “last known” values quickly (without time-series noise)

  • Validating identity fields (asset name/IDs)

  • Verifying if telemetry appears stale (if values do not change when you expect them to)

How to run a Current State query

  1. Set Search Mode to Current State.

  2. Select one or more assets.

  3. Add the signals you want to inspect.

  4. Select the Search / Run button.

  5. Review the results table and export if needed.

Using History mode

What History is best for

  • Understanding how a signal changed over time

  • Identifying patterns (oscillation, spikes, dropouts)

  • Proving “what happened when” during investigations

  • Validating whether a workflow condition would have triggered based on historical behaviour

History mode controls (left panel)

When you switch to History, additional controls become available:

1) View: Grid vs Chart

  • Grid: shows time-stamped records in a table format.

  • Chart: shows a time-series visual trend line.

2) Date Format

A dropdown that controls how time is represented (example shown: Last).

3) Days

A numeric selector (spinner) used to define how many days of history to retrieve (example shown: 12).

 

History: Grid view

Grid view is a table that includes a Timestamp column, enabling precise audit-style reviews.

Common columns include:

  • Asset ID

  • Timestamp

  • Signal

  • Current Value (value at that timestamp)

Usability

  • Best for investigations where you need exact times (incident timelines, compliance checks).

  • Useful for copying/exporting rows for evidence or analysis.

History: Chart view

Chart view visualises the selected signal over time. It is ideal for spotting:

  • trends

  • step changes

  • outliers/spikes

  • recurring cycles

Common controls visible in the chart view:

  • A legend identifying the asset series

  • A time-range slider at the top of the chart to narrow the visible window

If you are charting multiple assets or signals, keep selections minimal to maintain readability.

Exporting results

Export is available from the top-right of the results area and supports:

  • CSV

  • Excel

When to export

  • Sharing results with stakeholders

  • Attaching evidence to support tickets or investigations

  • Analysing data externally (pivoting, charting, correlation checks)

Tip: Use History → Grid before exporting when you need time-stamped evidence.

Best practices

  • Start with Current State to confirm the signal exists and is populated.

  • Move to History to investigate behaviour and timing.

  • Use Groups selection when you need a scalable way to analyse multiple related assets.

  • Keep signals focused: identity + the minimum telemetry needed to answer the question.

  • Export only once the results are filtered and correct to avoid rework.

Troubleshooting

No results or missing values

  • Confirm the correct asset is selected.

  • Confirm the signal is available for that asset type/device integration.

  • In History, increase Days to ensure your time window includes the event.

Values look stale in Current State

  • Check whether the device is actively reporting.

  • Use History to confirm when the last changes occurred.

Chart looks misleading

  • Switch to Grid to verify exact timestamps and values.

  • Narrow the range using the time slider for better resolution.
