Installing the PWA on your phone

Mon, 01 Jan 0001 00:00:00 +0000

Installing the PWA on your phone#

The ELT Field Service app (PWA, Progressive Web App) runs in a browser, but you should install it to your phone’s home screen: it then launches like a normal app, hides the browser’s address bar, and push notifications + background sync work more reliably.

Android (Chrome)#

Adding to the home screen#

Open https://mobile.work.elt.systems in Chrome.
Register this device with the enrollment code from the office — see Device setup and login.
Open Chrome’s three-dot menu (⋮) and pick “Install app” (or “Add to Home screen”).
Confirm — the icon appears on your home screen as ELT FSM.
Launch it from there → it looks like a real app, no browser chrome.

Enabling push notifications#

Notifications are not on by default — you activate them once. After that you’ll get a notification each time you’re assigned a task or an assistant-installer request comes in.

Device setup and login

Mon, 01 Jan 0001 00:00:00 +0000

The PWA uses biometric login — fingerprint or face recognition. You never type a password or an API key. Your phone is paired to you once using a code from the office, and after that you open the app with a single biometric unlock.

**The old method has been removed.** Logging in used to require a server URL, database, username and API key (plus a PIN). That's gone — the only way now is biometric device registration, which is both safer and faster.

How it works in short#

The office or your foreman creates a 9-character enrollment code for you on the desktop (valid for 15 minutes).
On your phone you open https://mobile.work.elt.systems → Register this device → enter the code or scan the QR.
The phone asks for your fingerprint / face (or device lock code) → the device is paired.
From then on, logging in is a single biometric unlock. No password, no API key.

1. Registering the device (once per phone)#

You only do this once for a new phone.

Working with tasks

Mon, 01 Jan 0001 00:00:00 +0000

Working with tasks#

A task — Field Service Order — is one unit of work: one customer, one site, one visit. The installer sees their tasks in the PWA.

Task states#

State	Meaning
Planned	Office has created the task, work hasn’t started
In progress	You’ve started the work — clock running
Done	You marked the task complete, foreman approves for invoicing
Cancelled	Won’t happen (e.g. customer not on site)

Using the task list#

The PWA home view shows:

Logging hours

Mon, 01 Jan 0001 00:00:00 +0000

Logging hours#

You can add hours from two places: per task or via the general Hours view. The result is the same; the choice is about ergonomics.

Per-task hour entry#

When you’re in a task:

Open the Hours tab.
"+ Add hours" button.
In the modal:
- Date — calendar picker. You can collapse the calendar if you don’t need it.
- Hours — e.g. 1.5 or 1:30. Both decimal and colon work.
- Custom task dropdown — optional, if you want to specify which sub-task (“Electrical”, “Travel”, “Break”).
- Description — optional note.
Save → the line appears in the list and syncs to the server (or queues if you’re offline).

General Hours view#

When you want to see all your hours for the day/week/month in one list:

Drive time and route tracking

Mon, 01 Jan 0001 00:00:00 +0000

Drive time and route tracking#

Drive time is logged separately from work time. The reason is working-hours law: drive time doesn’t count as actual working time, but it does affect pay (in some collective agreements drive-time pay can be e.g. half of the work rate). The split also gives a clean audit trail for yearly working-hours tracking.

Start drive / End drive#

In the task view, below the work buttons, there’s a 🚗 Start drive button.

Logging expenses

Mon, 01 Jan 0001 00:00:00 +0000

Logging expenses#

Expenses are all work-related costs not yet billed to the customer: mileage, per diems, materials (if you bought something on site from a reseller), and other (parking, waste fees, toll/ferry fees).

Typical expense categories#

Category	What it is	Tax-free limit
Mileage	Use of your own vehicle	Set yearly by the tax authority
Per diem (partial / full)	Working more than 6 h away from home	Set yearly by the tax authority
Meal allowance	Lunch on a trip	Set yearly by the tax authority
Material	Item bought on site	Per the receipt
Toll fee	Tunnel, ferry, parking	Per the receipt
Other	Anything else work-related	Per the receipt

**The office defines the exact reimbursement classes and amounts** annually, following the tax authority's rules. The PWA's expense- category dropdown shows the currently valid options.

Adding an expense to a task#

When you’re in a task:

Registering equipment

Mon, 01 Jan 0001 00:00:00 +0000

Registering equipment#

When you install a new device at a customer site (heat pump, ceiling heater, AC unit, lighting sensor, …), you should register it in the customer’s equipment list. This pays off in:

Warranty handling — when a fault comes up in 2 years, any installer can see which device, from which supplier, when installed.
Service history — for each device, all tasks involving it are shown.
Contract customers — the office reports the equipment in the registry.

Registering from a product line#

The easiest path: you’ve already added a product line to the task (e.g. a Nibe F-series heat pump). From there:

Adding photos to tasks

Mon, 01 Jan 0001 00:00:00 +0000

Adding photos to tasks#

Photos are the primary way to document work. They protect both the installer (“I did exactly this”) and the customer (“this is how it was before”). You can add unlimited photos — the old 10-photo limit is gone.

When to take a photo#

Before starting — overall site, the old device, wiring you’re about to remove.
During the work — phases if something turns out differently than expected (e.g. “behind the electrical panel was not what I expected”).
When done — the final result. Customers want this as a record.
Defective parts you replaced — sometimes the supplier wants a photo for warranty processing.
Wiring diagrams / device internals — helps a future installer who comes to the same site.

Adding a photo to a task#

When you’re in a task:

Offline mode

Mon, 01 Jan 0001 00:00:00 +0000

Offline mode#

The PWA is designed to work in the field without internet: basements, parking garages, remote sites, “5G not here yet” country roads.

What works offline#

✅ Browsing tasks — last-fetched tasks and their details are cached.

✅ Logging hours — the modal works normally, the saved line queues.

✅ Logging expenses — same as hours, including receipt photos stored locally.

✅ Adding photos — camera opens, photo stores locally, queues for upload.

Notifications (push)

Mon, 01 Jan 0001 00:00:00 +0000

Notifications (push)#

Push notifications are the fastest way to know that you’ve been assigned a new task or that the foreman needs help. They arrive in the phone’s notification bar even when the PWA is closed or the phone is locked.

What notifications you’ll see#

Situation	Notification
New task assigned to you	“Assigned to task: FO023 — Electrical work”
Assistant request	“Help requested: Kalle / FO024”
Approval received (hours / expenses)	“Your hours for week 21 approved”
Other foreman message	Subject as the title

Tap the notification → the PWA opens directly on the right task.

Completing work and the work report

Mon, 01 Jan 0001 00:00:00 +0000

Completing work and the work report#

When the job is done you mark the task complete, optionally take the customer’s signature, and the system builds a work report PDF (hours, drive time, km, photos, route map, costs and signatures).

First, once: your own signature#

Draw your own signature once in settings — it is automatically stamped onto every work report under “EL‑Tekniikka / Installer”.

Settings → the “Signature” section.
Tap "✍️ Create signature".
Turn the phone landscape (or tap the ⟳ button) — the signing pad needs landscape orientation.
Draw your signature on the white area and tap “Save”.

The signature is saved on the server. You can replace it any time ("Sign again") or remove it ("Delete"). Saving requires internet once.

Completing the task (“Done”)#

First make sure hours, drive, products and photos are entered. Add photos from the Photos tab before marking the task done — see Adding photos.
On the task screen tap "✓ Done" → the summary screen “Work complete” opens.
Review the summary: Work hours, Drive time, Breaks, Products and the preliminary cost estimate.
Edit the “Task & summary” text into a customer‑friendly form (saves automatically). This text appears on the work report and the invoice.
Customer signature (optional): tap "✍️ Sign the task", let the customer sign → the signing time is shown. You can delete it or sign again.
Tap "✓ Confirm" → the confirmation prompt “Mark the task as done?” → “Confirm”.

**After confirming you can no longer edit the task yourself** — the timer stops, materials are recorded as consumed, and the task moves to billing‑ready. Undoing it needs a foreman. So add photos and check the details **before** confirming (or within 7 days — see [Documents and completed tasks](../dokumentit/)).

Confirmation requires internet, because the summary is saved on the server.

Documents and completed tasks

Mon, 01 Jan 0001 00:00:00 +0000

Documents and completed tasks#

Two related things: the PDF documents attached to a task, and the 7‑day finishing window for recently completed tasks.

Documents (PDFs on a task)#

A task can have PDF files attached — for example work instructions, floor plans, or the finished work report.

Opening: open the task → tap the tab selector at the top (defaults to “General”) → choose "📄 Documents".

PDFs attached by the office appear in the list with an “office” badge. You can open them but not delete them.
Add your own PDF: tap "📄 Add PDF" → pick a PDF file (max 25 MB) → add a caption if you like (“Optional caption, e.g. Floor plan 1st floor”) → “Save”.
Open a PDF: tap the row → the file opens in your phone’s PDF viewer.
Delete: only PDFs you uploaded yourself (trash icon). You can’t delete ones the office attached.

Documents attached by the office sync with the task (visible offline too). Adding a new file requires an internet connection.

Completed tasks (7‑day finishing window)#

Opening: menu (☰) → “Completed tasks”.
