For your business · Something you have to check every day, that bites when you forget

Things that watch, so you don't have to

A spreadsheet changed, a gate left open, a person in the shed after hours, a machine gone quiet: one text, to the right person, when it matters.

The chore

Every business has a thing that has to be checked. A shared spreadsheet somebody else controls. A gate. A fridge. A machine that’s supposed to be running. A back door at 2am. You check it when you remember, and the day you forget is the day it matters.

What runs now

A watcher sits on the thing and knows what “normal” looks like. When it changes, you get one message, with what changed, and nothing else. No daily “all fine” noise, no app to open, no dashboard to remember.

Some watchers I’ve already built and run:

  1. 2:14 amWorkshopPerson detected inside after hours. Siren on, calling you now.
  2. 5:40 pmRoller doorOpen for 5 minutes with nobody around.
  3. 8:02 amPay sheetRow 14 changed while you were locked out: 11.5 hrs became 8 hrs. Old copy saved.
  4. 9:15 amBackupLast night's backup did not run. Disk was full.
  • A spreadsheet that drives your pay, controlled by someone else. Pulled on a schedule, compared line by line with the last copy, and any change texted to you, with special attention to changes made while you couldn’t see it.
  • A roller door left open. Five minutes with nobody around, one text.
  • The workshop after hours. A camera that knows the difference between a person and a cat. Person gets a siren and a phone call; cat gets nothing.
  • A machine, a service, a backup. When it stops, one message. Not fifteen.

What changed

The forgetting stopped mattering. And the messages are rare enough that when one arrives, you read it.

What it took

Depends entirely on the thing being watched: a camera, a door sensor, a login to the spreadsheet, or nothing at all if it’s already a computer. That’s what the scoping conversation is for.
