Your store never sleeps.
Neither does M4.

M4 watches every fridge, freezer and cool room, 24/7. Real-time alarms reach the right person straight away, an AI analyst spots the patterns alarms can't, and you can see your whole store, live, in 3D.

The problem

After hours, nobody's watching. That's when stock is lost.

A display that warms overnight, a freezer that won't hold, a sensor in the wrong place. By morning it's waste, risk and a scramble for evidence.

Overnight

Problems start when the store is empty

Defrosts run long and doors get left ajar. Nobody sees it until opening, when the stock is already gone.

Noise

Too many alarms, so people stop listening

Hundreds of nuisance alarms a week train teams to ignore the one that matters.

Blind spots

Thresholds miss slow problems

A cabinet that freezes for a day, or one that sits at the top of its range every night, never trips a simple limit.

Real-time alarms

The right person knows, straight away.

When a reading leaves its limits for longer than you allow, M4 opens an alarm and works down your escalation ladder: people, roles and timing you set. One tap acknowledges it, and the escalation pauses.

  • Escalation ladders by person or role
  • One-tap acknowledge, full timeline
  • Not-reporting watchdog for silent sensors
  • Opening hours, holidays and maintenance mode

Less noise

Tune your alarms against last week, before you save.

Pick how sensitive each profile should be and M4 replays the last seven days on the spot, so you can see exactly how many alarms the new setting would have raised.

  • Backtest every change on real readings
  • Sensible presets: Sooner, or Fewer alarms
  • Separate rules for chilled, frozen and prep

M4 AI analyst

Alarms catch the moment. M4 catches the pattern.

Every week, M4's AI analyst reads each unit's readings, compares it with its neighbours and writes up what's worth your attention in plain English, with a next step. Every number is recounted from the readings before you ever see it.

See everything

Your whole store, live, in 3D.

Draw your floor plan once and every reading lands where it belongs. Heat maps respect your walls, alarms pulse where they happen, and one click lifts the plan into a live 3D view of every fridge and room.

  • Live heat maps that never cross a wall
  • 40 realistic equipment types in 3D
  • Draw your own floor plan, no CAD needed

Set & forget

Bring your own sensors. Scan, place, done.

M4 works with the sensors you already have. Scan a sensor's QR label with any phone to claim it, drop it on the plan, and M4 handles the rest, including backfilling logged history after an outage, so there are no gaps.

  • BYOD: bring your own sensors
  • Scan & go with any phone camera
  • Battery and signal health for every device

The film

70 seconds. One night. The real product.

Everything you see is M4 running on real store data. Sound on.

How it works

Live in days, not months.

  1. 01

    Scan your sensors

    Point a phone at each sensor's QR label to claim it. Bring your own sensors, or start with ours.

  2. 02

    Draw your store

    Sketch rooms and equipment on the floor plan, or line them up over a photo of your plan.

  3. 03

    Set the rules

    Choose alarm profiles for chilled, frozen and prep, and backtest them against last week before you save.

  4. 04

    Sleep easy

    M4 watches 24/7, alarms the right person, and the AI analyst reports what's worth a look each week.

Your store never sleeps.
Neither does M4.

See M4 on your own store. We'll map your fridges, freezers and rooms and show you what it would have caught last week.
