Device page

Every device supervised by Drexo has its own detail page at /<organisation>/devices/<id>. The page adapts automatically to the device type: an Itron water meter doesn't show the same blocks as a pool sensor or a connected TV.

This guide covers the water meter page (type: water_meter), the most common type today, then the page of a Shelly plug.

How to reach it

Three paths to the page:

• From the left rail: expand your organisation, then a zone, then click the meter's name.
• From Shared with me: click the card or the device name.
• From a dashboard: click any device widget to land on its full page.

The URL accepts a time-window parameter:

• ?range=1: last 24 h
• ?range=7: last 7 days (default)
• ?range=30: last 30 days
• ?range=90: last 90 days

What the page shows

1. Header

• Device serial number + internal name.
• A decoder badge naming the meter family (e.g. Itron Intelis wSource).
• Alarm chips for every currently-raised alarm.
• Three actions on the right:
  • Pin / Unpin from a personal dashboard.
  • Rename for my organisation: alias shared by every member of your organisation.
  • Rename for me: strictly personal alias, invisible to other users.

The organisation nickname, tags, zone placement and dashboard pinning can also be edited straight in the grid of the Data surface. The grid and the device page write to the same place: a change made on one side shows up on the other.

On a Map or 3D Map view of the Data surface, an Admin can also move the device's registry position directly on the map. A device whose displayed position comes from its own telemetry (fresher than the registry) stays readable but cannot be moved.

2. Stats strip

Four key figures across the chosen time window:

• Average per day: total consumption ÷ number of days.
• Total over the window.
• Hourly peak: the biggest single-hour consumption observed.
• Corrupt frames: count of frames received but undecodable. A healthy meter stays at zero; a rising value signals a reception or hardware issue.

3. Side-by-side charts

• Daily total: bars; one day = one bar. Quick read of high / low days.
• Hour-of-day profile: average per 0–23 h slot. Surfaces habits (morning peak, night trough, continuous 24/7 leak, etc.).

4. Hourly heatmap

A days × 24 hours grid where colour encodes the amount consumed per cell. Effective for:

• spotting a leak (non-black tint every night for hours);
• spotting a one-off anomaly (a dark cell isolated at 3 AM);
• seeing weekends and holidays at a glance.

5. Alarms

• Active alarms listed on top, with raised-at timestamps.
• History of resolved alarms below (last 100 by default).

See Alarms for the full list of alarm types and their severity.

6. Recent volume-index measurements

Table of the raw measurements the meter has reported, time-stamped. Useful for operators who need the exact value the device returned before any Drexo computation.

The page of a Shelly plug

A Shelly plug (type: shelly) has its own page. It is deliberately minimal for now: it confirms that measurements arrive and shows the last 24 hours of consumption, with no time-window picker.

What the page shows

The page fits in one card:

• At the top, the Shelly plug's name, then its live power: what it draws at the time of the measurement, in the unit it was sent in (W, watts). Hover the value, reach it with the keyboard or tap it to see the time of the measurement, in UTC, as announced by the bridge that reads the Shelly plug. The name sits on the left, the value on the right.
• Below, two charts, each in its own section, in this order: Puissance instantanée (10 min) (live power, 10 minutes), then Consommation totale (24h) (total consumption, 24 hours). Each chart labels on its vertical axis the maximum ("max") and the mean ("moy.") of what it draws, and nothing at all when it has nothing to draw. Each section has its own i button showing its legend. The total consumption one also gives the Shelly plug's own counter as it was sent (W.h, watt hours), with the time of that measurement. Drexo does not recompute the counter.

The four states

When all is well, the card shows no state. Otherwise a label sitting on the card's top-right corner says it in words, in its own colour:

• Up to date (nothing shown): the latest measurement reached Drexo less than two minutes ago, which is four measurements of the Shelly plug.
• Ancienne (old, slate-violet label): the latest measurement arrived longer ago than that. The value stays on screen, but it no longer says what the Shelly plug draws now. Age is judged on the time the measurement reached Drexo, not on the time announced by the bridge, whose clock can drift.
• Aucune mesure (no measurement, amber label): nothing has arrived for this Shelly plug, and a sentence under the name says so. When it has been registered for more than 30 days, the page only says that no measurement has arrived for at least 30 days: Drexo does not look further back.
• Lecture impossible (read failed, rose label): Drexo could not read the measurements. This is not a silent Shelly plug: the page shows no value at all, never a zero, and each chart's place shows a grey shape with no values and a soft shimmer (still if you reduce motion), under the sentence that explains it. If only one chart could not be read, the value and the other chart stay, and only its place changes.

The state is computed when the page opens: reload it to refresh. Only people with access to the Shelly plug see its page and its measurements.

Power over the last 10 minutes

The Puissance instantanée (10 min) section draws every power measurement of the last 10 minutes, in W (watts), as a smoothed line. The bridge reads the Shelly plug every 30 seconds, so about twenty points. If a Shelly plug is read more often than every 10 seconds, the line keeps the last measurement of each 10-second slice. The smoothing never goes past the measurements: between two points, the line stays between their two values.

• The line is cut wherever at least one measurement is missing, for example because the link dropped. That gap carries a small grey cross, and nothing is drawn in it, neither a zero nor a guessed value.
• Hover a point, tap it, or reach the chart with Tab and walk its points with the arrow keys (Home and End jump to either end): each point gives its time and value, each gap its bounds.

The counter over 24 hours

The Consommation totale (24h) section draws the Shelly plug's counter over the last 24 hours, up to the current hour, in kW.h (kilowatt hours): one point per hour, the last measurement of that hour. Hours are the ones the bridge announces for each measurement, in UTC, not the time the measurement reached Drexo. Since the counter does not start at zero, the vertical axis also labels its lowest value ("min").

• An hour with no measurement carries a small grey cross and cuts the line.
• A counter that started again from zero (the Shelly plug pulled out of the wall outlet and put back, for example) cuts the line too: what follows starts lower, with no stroke going down. A counter never goes backwards, so a drawn line never goes down.

Its points read like the power chart's: hover, tap, or Tab then the arrow keys. If the bridge changes unit during the day (W.h, then kW.h), each measurement is converted; a unit that does not convert to energy is reported and the line is not drawn.

Allow a day of the bridge running to see all 24 points: a Shelly plug installed this morning only has the hours since then. Both charts are computed when the page opens, like the state.

Ask the assistant

The Ask AI button at the top right opens the chat with the device's context pre-loaded. You can ask things like:

• "What's the average daily consumption over the last 7 days?"
• "Did any alarm fire last night?"
• "Does the hour-of-day profile suggest a leak?"

The assistant never makes up numbers: it calls the same data sources the page itself uses, and cites the public documentation when you ask about how the platform works.

Sharing the device

If you are an Admin of the organisation the device belongs to, a Share button appears in the header. See Sharing for the options (personal, organisation, public link).

Otherwise, when you receive a share, you can:

• open the page to consult the data,
• optionally place the device in a zone of your own organisation (when the person who shared allows it),
• or leave the personal share (Leave share button at the bottom of the page), which revokes your access.
