When the Signal Disappears, the Job Still Has to Move. How Do You Build a Smart Meter Field Service Platform That Works Offline
Engineers were installing regulated assets in locations where connectivity could not be guaranteed. Emvigo built an offline-first field-service ecosystem that kept jobs, assets, commissioning and data moving.
Project Overview
Smart Meter Installation Doesn't Stop When the Network Does
A UK energy technology provider supporting smart meter installations needed field engineers to execute jobs reliably across properties where mobile connectivity could be poor or unavailable. The platform also had to track regulated assets throughout their lifecycle and coordinate commissioning across multiple DCC adapters.
The challenge extended beyond connectivity. Jobs involved dynamic worksheets, complex asset states, barcode and Bluetooth scanning, conditional business rules, and strict requirements around saving job data before completion. Office teams also needed visibility into jobs, engineers, vans, assets, and outcomes without relying on manual refreshes.
Emvigo came in as a development and QA partner, delivering a two-part field-service ecosystem: an Android mobile application for engineers and a Django-based web portal for administrators. The result was a resilient, offline-first platform built around real field conditions.

The Challenge
The Field Was Unpredictable. The Platform Had to Be Anything But.
Smart meter installation combines physical fieldwork with regulated asset management, complex commissioning workflows and backend dependencies. The platform needed to remain reliable across unreliable networks, multiple Android devices, and several operational edge cases.
Customer Perspective
- Engineers needed to capture job information, scan assets, and trigger commissioning even with limited or no connectivity.
- Different job types required dynamic worksheets and workflows without forcing engineers through irrelevant steps.
- Asset scanning needs to work reliably across camera and Bluetooth devices without false “not found” results.
- New jobs, cancellations, and asset transfers need to reach engineers without constant manual refreshing.
Business & Operational Problems
- Multiple DCC adapters returned different formats, errors, and orchestration requirements, complicating a consistent commissioning workflow.
- Regulated assets moved through numerous states, with business rules determining when transfers, audits, and other actions were permitted.
- Job completion required backend reconciliation to ensure worksheet responses were persisted before the job could be closed.
- Heavy local state and device limitations created crash risks across the range of Android hardware used by field engineers.
Running field operations where poor connectivity, regulated assets, and complex workflows cannot be allowed to interrupt the job?

Product Strategy
Emvigo's Strategic Role: Designing for the Field First, Not the Office Network
Emvigo approached the platform around the conditions engineers actually face: unreliable connectivity, device constraints, asset-scanning requirements and jobs that cannot simply be restarted when something goes wrong.
The architecture separated field execution from administrative control while keeping both connected through synchronisation, notifications, and shared operational data. An offline-first approach allowed work to continue locally, with queued data synchronising when connectivity returned.
A disciplined QA and release process then ensured each iteration was tested against defined Android devices and operational workflows before release.
01
Offline-First Field Execution
Jobs, answers and asset activity can continue locally when connectivity drops, with queued data synchronising once the network returns.
02
Reliable DCC Orchestration
A common commissioning layer translates requests across Ensek, Seaglass and uSmart, while handling responses, retries and correlation tracking.
03
Rule-Based Asset Control
Asset movements and operational actions follow defined business rules, ensuring the right actions are available at the right stage.
04
Data Integrity at Job Close
Completion includes backend comparison and reconciliation, so captured worksheet data is not silently lost before a job is closed.
05
QA-Led Device Reliability
Documented testing and an Android compatibility matrix helped validate releases across the devices used by engineers in the field.
Our Solution
Two Interfaces. One Field-Service Ecosystem. Built to Keep Work Moving.
Emvigo delivered an offline-first smart meter field service platform connecting engineers in the field with administrators managing jobs, assets and operational reporting.
Offline-First Engineer Mobile App
A React Native Android application supporting job execution, dynamic worksheets, asset scanning and DCC commissioning. Local sync queues preserve work when connectivity is unavailable.
Dynamic Jobs and Worksheets
The platform supports DFE, OFD/OFE/OFG, collection orders and van audits, with job-specific questionnaires and controlled complete or abort workflows.
DCC Commissioning Integration
An orchestration layer standardises interactions across Ensek, Seaglass and uSmart, handling pre-checks, response mapping, retries and DCC UUID tracking.
Full Asset Lifecycle Management
Assets move through defined states from ASN Received and On Van through Installed, Removed, Returned, and Handover, with history maintained throughout the lifecycle.
Bulk Transfers and Van Audits
Engineers can move multiple assets between vans in a single flow, while rule-governed van audits support stock reconciliation and validation.
Admin Portal and Live Notifications
The Django portal provides job, engineer, van, and asset management, reporting, and CSV export, while push and web notifications alert teams to new jobs, cancellations, and transfers.
Business Outcomes
Offline-First Fieldwork. Three DCC Adapters. Full Asset Visibility From Van to Installation
Reliable Field Execution Without Signal
The offline-first architecture keeps engineers productive in low- and no-signal locations, synchronising queued work when connectivity returns.
One Commissioning Workflow Across Three DCC Adapters
The integration layer provides a consistent commissioning experience across Ensek, Seaglass, and uSmart despite differences in responses, errors, and orchestration.
Bulk Asset Movement Replaces One-by-One Processing
Van-to-van transfers allow multiple assets to be moved in one workflow, reducing the need to process each asset individually during transfers and audits.
Job Data Reconciled Before Closure
Job Data Reconciled Before Closure The job completion process compares backend data and patches missing answers before closing, reducing the risk of incomplete worksheet information being lost.
