Pulse Edge plugs straight into your Gallagher TW-1 weigh scale and HR4 SmartReader. Every weight, every EID tag — captured at the race, understood on the spot, and ready the moment you ask. Even with no signal.
No re-keying, no spreadsheets, no waiting for the office. Pulse Edge listens to your Gallagher devices over Bluetooth and turns raw reads into living records.
Pulse Edge is a rugged on-farm hub that sits between your Gallagher hardware and the Pulse cloud — doing the thinking right where the work happens.
You weigh on the TW-1 and scan the EID tag with the HR4 — exactly as you do today.
The Pi pairs over Bluetooth, reads each weight + tag, and buffers it in a crash-safe local database.
It matches tag→animal, calculates daily gain, flags outliers and builds draft lists — instantly, offline.
When there's signal it syncs to your Pulse account. Ask Pulse anything, by voice or WhatsApp.
A hardened Raspberry Pi 4 running the Pulse Edge agent — offline-first by design, so the farm never goes blind when the broadband does.
heartbeat → server every 60s
batch sync every 5 min · auto-retry on signal
AES-256-GCM encrypted credentials
This is exactly what happens on the stand. Press the button and watch a weigh + scan flow from the crate to a decision.
Pulse Edge doesn't just record the weight — it works out what it means for that animal, then surfaces it where you'll actually use it.
Captured once at the race, your Gallagher data flows into everything Pulse does for you.
Per animal, per group, per mob — tracked automatically so you spot the thrivers and the laggards early.
Draft by weight or gain into the TW-1's groups. Pulse suggests the cut-offs from your targets.
Movements, weights and tag reads logged to each animal's record — audit-ready, no paperwork.
Liveweight gain against feed and inputs — so you know the true margin on every head.
Sudden weight loss or a missed target triggers an alert before it becomes a problem.
"Show me steers under 0.8 kg/day." Answered from live race data — by voice or WhatsApp.
The weights and EID reads from your Gallagher TW-1 and HR4 don't just get recorded — every weigh, scan and movement is written as a tamper-evident, cryptographically chained record and anchored to a public ledger. So when a buyer, processor or auditor asks "is this real?", the answer is provable, not just promised.
Each weight on the TW-1 and EID tag on the HR4 is captured at the race — the raw, signed source event.
On Pulse Edge and Pulse, every weigh, scan and movement becomes a SHA-256 audit entry that links to the previous one via its previousHash — a chain you can't quietly edit.
Records are batched into a Merkle tree; the root is ECDSA-signed and anchored to the Hedera public ledger (testnet — pilot), timestamping the whole batch.
Anyone can verify an animal's full, untampered history at /api/verify/animal/<tagId> — replaying the hash chain against the anchored root.
Same Gallagher kit, same race-side workflow — now with a verifiable trail behind every number. Anti-fraud, audit-ready, farm-to-fork provenance, built in from the weigh crate up.
The cattle aren't always near the router. Pulse Edge keeps capturing and deciding offline, then catches up the moment it finds signal.
