Report Builder

Build PDF reports from your sensor data, delivered on schedule

The Datacake Report Builder turns device data into finished documents. Drag KPIs, charts and tables onto a page, choose the devices, set a schedule, and every recipient gets the report by email: as a PDF, an interactive web view or both.

  • Drag-and-drop editor with KPI, chart and table widgets
  • Daily, weekly or monthly schedules with email delivery
  • PDF document, interactive web view or both
  • Ready-made templates for cold chain and energy reports

From monitoring data to a document people actually read

Dashboards are for the people who run the system. Everyone else (customers, managers, auditors, building owners) wants a document in their inbox. The Report Builder produces that document from the same device data: you design the layout once, and the schedule takes care of the rest.

Widgets

KPIs, charts and tables from any device field

A report is a page of widgets. Pick one from the library, drop it on the canvas and choose the field, the aggregation and whether it covers a single device or the whole fleet. The built-in preview shows the layout while you work.

  • KPI: average, minimum, maximum or sum over the report period
  • Time-series chart as line, area or bar
  • Time-series table at the resolution you choose
  • Fleet Consumption: start and end meter readings per device
Device Loop

Device Loop

Design one section, repeat it for every device

Put a heading, a KPI summary, a chart and a table inside a Device Loop and the Report Builder generates that block once per device. Rooms, fridges, meters or machines all get the same consistent layout without building the section again and again.

  • Up to 100 devices per loop
  • Device header with name, serial number and location
  • New devices with a matching tag are included automatically
Device hierarchy configuration with two tag-based levels and a preview of the grouped devices

Device Hierarchy

Group devices by building, floor and room

Larger installations rarely read well as one flat device list. Define hierarchy levels from the tags your devices already carry, and supported widgets group and roll up their values per level. A preview shows how many devices match before you apply the change.

  • Levels such as Building, Floor and Room, defined by tags
  • Optional levels keep devices without a matching tag
  • Preview lists unmatched devices before anything is saved
Report schedule settings with weekly frequency, time of day, previous-week time range, resolution and time zone

Schedule & Period

Daily, weekly or monthly, in your time zone

Each report runs on its own recurring schedule and covers the period you define, for example the previous week. The resolution controls how the data is grouped: fine intervals for detailed tables, daily values for a condensed overview.

  • Frequency, time of day and time zone per report
  • Resolution from 15 minutes to one day
  • Start of week on Monday or Sunday
Output settings with PDF document and interactive web view selected and a locale for language and number formats

Output & Delivery

PDF, interactive web view or both

Generate a PDF to download, print and file, a browser-based interactive version, or both. Recipients get an email with a link as soon as the report is ready, optionally with the PDF attached. Reports that leave your organization can be protected with a password.

  • Email delivery with a recipient list per report
  • Optional PDF attachment and password protection
  • Locale sets language, date and number formats

Custom Branding

Reports that carry your brand identity

White-label customers can deliver reports under their own brand instead of Datacake's, so the document your customers receive looks like it comes from your own platform.

Start from a template or a blank page

Cold Chain Monitoring

Temperature and humidity compliance across your cold chain: status table per device or group, excursion list and reviewer sign-off.

Explore the cold chain template

Energy Consumption

Energy usage trends and consumption analytics, including per-device consumption with start and end meter readings.

From Scratch

Start with a blank canvas and add your own widgets. Works for any numeric field: temperature, CO2, noise, fill levels, energy and more.

Every generated report in one archive

Each run appears under Generated Reports with its status, the PDF and web view, the creation date and the expiry date. Search by report name or ID to find the document an auditor or customer is asking about.

Report Builder capabilities

Tag-Based Device Selection

Select devices directly or filter them by name and tags, combined with AND or OR. Tag a new device and it joins the next report.

Data Gap Handling

Decide per report how missing measurements are treated: fill forward, interpolate or leave empty. Leaving gaps empty keeps compliance reports to what was actually measured.

Print-Ready Pages

A4 or Letter, portrait or landscape, with forced page breaks wherever a new section should start on a fresh page.

Language & Regional Formats

The locale of a report controls its language and how dates, times and numbers are written in the PDF, the web view and the email.

Password Protection

Require a password to open report links and downloads when reports contain sensitive data or are shared outside your organization.

Workspace-Scoped

Reports are configured per workspace and only contain devices from that workspace, which keeps customer data separated in multi-tenant setups.
