Key Takeaways
- A grain-elevator SMS is a scale-house event: dump ticket, moisture, and dockage — not a “truck late” line-haul ping.
- Scale-house SIM and farm-dispatch SIM stay split. One radio mixing both is how a STOP kills the next harvest window.
- Free is 1 device, 300 SMS lifetime, and 300 contacts. Developer is 25,000 SMS per year. Platform price is devices plus send volume.
- Grower-portal OTP stays off the elevator chassis.
- Idempotency is ticket-id plus dump-window — houses reprint after a moisture retest.
Summary
Scenario 1011 is dual-SIM routing for grain-elevator dump tickets — wheat, corn, soy — not oversize blades, not city vans, not cold-chain, not port gates, not barge tows. A pit queue slipped. Only the scale house and that grower’s truck should hear “hold at lane 3.” Service pricing is devices plus SMS send volume. You bring the phones and operator credit. Free is 1 device, 300 SMS lifetime, and 300 contacts.
Starter allows 2 devices: scale dual-SIM plus a spare chassis. Uncapped platform volume is not unlimited carrier SMS. Confirm routing fields in Developer Center.

A dump ticket is not a line-haul ETA
Ticket copy names the pit and the grade. Line-haul “ETA +40” belongs on a different purpose. Mixing them means a grower STOPs after one marketing blast and never hears the moisture hold.
Multi-device and dual SIM, transactional SMS.
If dispatch texts every farm on the county because “the elevator is busy,” you will get a complaint. Route to ticket-id parties only.
Elevator routing matrix
| Event | SIM | Failure |
|---|---|---|
| Moisture hold | Scale house | Line-haul template reused |
| Pit swap | Farm radio | County dump copied |
| Ticket reprint | House, once | Two “new ticket” texts |
| Portal OTP | Auth pool | OTP on the elevator radio |
Scale house vs farm radio
Persist ticket-id plus dump-window. Signed callbacks. Webhooks, DLR. MCP wraps REST only.
Grade holds and STOP
Promo “lock next year’s basis” needs STOP on a merch ledger. USDA grain grades is not a reason to SMS the whole county directory.
Devices, volume, and airtime
Harvest nights spike. We meter devices and platform sends. You pay the operator. Free (1/300/300) is one dry-run ticket.
Harvest operations
Charge both chassis before the first dump. Setup, Downloads, pricing.
Decision guide
Ship when scale and farm SIMs are split. Delay if one SIM does moisture and basis ads. Not a CodeCanyon elevator pack.
Elevator checklist
- Ticket-window idempotency.
- Farm copy off county purpose.
- OTP off elevator SIMs.
- Reprint sends once.
- Developer Center fields confirmed.
