VisionDesign rev A, 28 Oct 2026: smart stock trough that runs the water point (9 calls, 7 alone, 2 assist), call lights, tone, ATECC608 and tamper switch inside the valve cover; 21 camera and sensor views checked in the CAD; not built

FarmOne

IEMI's one product for a farm's water point: the stock trough itself, made smart

The 600 L stock trough already on the fence line, at the same size and on the same supply, calls a cut supply, a stuck float, a leak and ice, counts visits and litres for both paddocks, times a calving, flags an animal down, a dog at the water and fouled water, and warns of frost and heat stress, all on solar with LTE-M.

Who buys it: Beef, dairy-youngstock, sheep and mixed farmers and graziers with 3 to 30 troughs, who drive a water run every day today; sold through farm stores and trough dealers.
Why it pays: $1,490 + $9/month per trough instead of about $1,594 + $135/year for TroughTally with WinterWatch and its gateway, a CalveClock hub with a PenEye and bell, and a plain 600 L trough bought separately (est.).
Target price: $1,490 per trough (replaces the trough) + $9/month water point app with LTE-M (target)
First-minute wow: 06:52, the farmer is away at market: the fence-line trough sees the level falling with no water coming in while the mob drinks, goes red, and texts that the supply is cut with about three hours of water left.

What the research found

And how this design answers it

Rev A (28 Oct 2026): the farms flagship is the stock water trough itself. Valve cover: Raspberry Pi Zero 2 W brain, two Camera Module 3 Wide and two MLX90640 heat cameras in the water-side face (one pair per paddock), DAE AS200U-75P meter on the inlet riser, VL53L1X on the float, DS18B20, SHT45, MAX9814, Walter LTE-M and GNSS, ATECC608, D2F-01, piezo, two NeoPixel call lights, a 6 W panel flush in the top and four 18650 cells
Makes the water point's calls itself: supply cut, stuck float or leak, ice, stock not coming to water, calving clock, a dog or fox at the water, frost and heat stress alone; an animal down and fouled water go to the farmer; unsure means 'check'
Legal at the water point: the float valve and its air gap kept (Water Fittings Regulations, Guidance Note 9, BS 3445), the welfare rules on fresh, clean, unfrozen water met, 1,610 x 1,180 x 840 mm and no overhang checked in the CAD
Folds TroughTally, CalvingPen and CalveClock; crop jobs in the orchard, the pivot and the sprayer stay with their own products

Use case

A 120-cow suckler herd on 14 paddocks with 9 troughs

FarmerStockmanVet

01Trigger: a cut pipe, a stuck float, ice at dawn, a gate left open, a heifer calving, a dog among the calves
02Detect: meter, float sensor, probe, cameras, heat cameras, air sensor and mic inside the valve cover
03Act: the trough's own red, amber, blue or white call light on that paddock's side with a tone; SMS over LTE-M
04Log: one signed log per trough, shared with the vet or auditor by QR code

Outcome: No daily water run, water problems found in minutes, calvings timed, and both paddocks watched from one trough

How it works

Architecture

01
Sense: a water meter, a float sensor, a water probe, two cameras, two heat cameras, an air sensor and a mic inside the valve cover
02
Decide: water rules on the always-on Walter board; animal, calving and dog models on the Pi Zero 2 W; 'check' below the line
03
Act: the trough's own call lights and a tone
04
Tell: one signed log to the water point app over LTE-M

Open risks we are working on

Dirt, spit and splash on the water-side windows; the windows sit 60 mm over the rim and need a wipe on the water run (field test)
A 6 W panel in a northern winter may give only a few days of cloud cover; the Pi wakes only when stock are at the water
LTE-M coverage on remote farms varies; calls are stored and sent when coverage returns
Pose and calving models need field data from many breeds and coats
BS 3445 test of the cover, radio and IP67 are still to be done
