This page tracks what's changed on the Shell Campus The Hague EV charger dashboard, plus a quick overview of what it currently does.

What this dashboard does

• Shows the live number of available chargers at the location, refreshed automatically.
• A visual bar showing chargers available as a share of the total.
• A 12-hour history chart of availability, so you can see whether it's trending up or down.
• An optional browser notification you can turn on to be alerted the moment a charger frees up.
• Small indicators showing how many people are viewing the dashboard (👁) and how many have switched on charger-availability alerts (🔔).

Changelog

Charger count on your home-screen app icon

August 3, 2026

• When you've added the dashboard to your phone or tablet home screen and open it like an app, you can now switch on a badge that shows the number of available chargers directly on the app icon — so you can glance at your home screen without opening it. The toggle only appears when the dashboard is running as a home-screen app on a phone or tablet that supports icon badges (such as iOS/iPadOS); it stays hidden in a normal browser tab and on desktop. On iOS you'll be asked to allow notifications the first time you enable it, as that's what the system ties icon badges to.
• Note: the badge reflects the count from the last time the app was open, and refreshes while it's open. It does not update on its own in the background while the app is closed (that would need push updates, which aren't enabled).
• When added to the home screen, the app is now named “EV C16” so it's easy to tell apart from other charging locations.

Fixed content getting cut off when zoomed in

July 30, 2026

• When the browser was zoomed in, the dashboard was centred to the screen height and the top or bottom could be clipped (for example the alert toggle dropped off the bottom). The page now grows and scrolls when the content is taller than the window, so nothing is cut off.

Higher-resolution history chart

July 29, 2026

• The 12-hour availability chart can now be sampled on a fixed schedule (independent of who is viewing), so it records readings steadily instead of only when someone happens to open the dashboard. The result is a higher-resolution, smoother line with small realistic steps, rather than a few big flat plateaus with sudden jumps.

Corrected the available count (removed a double-subtraction)

July 28, 2026

• The reserved (VIP) and out-of-service chargers were being removed twice — once by name (their serial number) and once by an older rough compensation left over from before the by-name removal worked. That made the available number read a few too low (for example 7 where 11 of the 17 the Shell app lists are actually publicly usable). The leftover compensation is removed, so the count now reflects the publicly usable chargers.

Steadier readings (no false spikes)

July 27, 2026

• Occasionally the upstream data feed returns a single odd reading — for example many chargers briefly reported as busy at once. Such one-off glitches are now held back and only shown once the next reading confirms them, so the available count and its 12-hour chart no longer show sudden false drops. Genuine, gradual changes are unaffected.

Smoother trend arrow

July 27, 2026

• The up/down trend arrow next to the available count now fades out gradually over about five minutes once the number stops changing, and returns to full strength on the next change.

Home-screen icon and clearer chart

July 27, 2026

• Added an app icon so you can add the dashboard to your phone or tablet home screen (iOS/iPadOS and Android) and open it like an app.
• The 12-hour availability chart now has faint vertical time markers every few hours, making it easier to see when things changed.

Live alert indicator

July 24, 2026

• Added a bell indicator (🔔) next to the viewer count showing how many people currently have charger-availability alerts switched on. Hover over either indicator to see what it means.

More accurate and reliable charger count

July 24, 2026

• Chargers that should be left out of the count (reserved bays and one out-of-service unit) are now correctly excluded, so the available number better reflects what you can actually use.
• The dashboard now makes sure it's reading data for this exact location. If our location is ever temporarily missing from the data feed, it shows the last known figures (or "no data") instead of accidentally showing a different nearby charging point.

Self-hosted assets

July 24, 2026

• The Shell logo is now hosted here directly instead of being loaded from an external site.

Landing page and easier navigation

July 23, 2026

• Added a proper landing page at the root of the site, with a small animated illustration.
• Added this changelog page.
• The "Back" link now returns to whichever page you actually came from.

History chart, viewer count, and mobile fixes

July 21, 2026

• Added the 12-hour availability history chart.
• Added the "people currently viewing" indicator.
• Fixed a display issue that cut off content on iPhone-width screens, and removed the "POC" ribbon.

More reliable refreshing

July 14, 2026

• Made sure the automatic refresh always fetches a fresh reading rather than a cached one from an intermediate network layer.

Cookie notice

July 13, 2026

• Added a cookie notice covering both analytics and the functional cookie used for the viewer count.

Automatic deployment

July 10, 2026

• Changes to this project now deploy automatically.
• Fixed the trend arrow briefly flashing on first load.

First version

July 8, 2026

• Initial release: live charger availability with automatic refresh and an optional browser notification when a charger frees up.
