Installer on ELT — Work — Documentation

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.
Log in (with credentials from the office — see 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.

Login and language selection

The PWA needs four things to log in: server URL, database name, username, and an API key.

The office gives you these credentials. Open https://mobile.work.elt.systems on your phone and fill in:

Field	What it is	Example
Server URL	Pre-filled	`https://mobile.work.elt.systems`
Database	From the office	`kissa`
Username	Email or name	`firstname@elt.fi`
API Key	From the office — a long random string	`a1b2c3d4...`

**Don't use your Odoo password to log in to the PWA.** The PWA uses a separate API key. Your password only works for the desktop version (work.elt.systems).

“Remember me”#

Tick the “Remember me” box before logging in. After that:

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:

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.
