Stop 0 — Connecting All plans
Before the journey: your existing indicator becomes the source of the number.
The weighbridge itself stays as it is. The system reads your existing indicator over its serial port (RS-232), and every reading is recorded under the name of the scale it came from.
- Each scale is registered by name and branch in your account, and every reading carries the name of the scale that published it.
- No readings are accepted from a scale until WeighHub has approved it; the number of approved scales is what a plan limits.
- Each publishing device has its own device token; no logged-in user can write into the reading feed.
- Windows agent: installed on the weighbridge PC, it reads the serial port and publishes the reading.
- ESP32 device: a small device we ship ready, wired straight to the indicator, that publishes the reading with no PC in between.
Works with most indicators that have a data output. If yours only shows the number on its display, replacing the indicator alone is far cheaper than replacing the bridge — and we tell you that before any contract.

| Windows agent | ESP32 device | |
|---|---|---|
| What it needs | A Windows PC at the weighbridge and a serial cable (RS-232) from the indicator. | An ESP32 device we ship ready, a cable from the indicator to it, power, and WiFi in the scale room. |
| How it works | Reads the data frame from the port and publishes the reading about once a second. | Reads the serial port directly and publishes the reading about once a second, with no PC. |
| When it fails | The weighing screen shows "bridge offline" and no stale reading is captured. The reading stays on the local PC because the link is local, and quick weighings are sent when the connection returns. | The weighing screen shows "bridge offline" until readings return. There is no PC in between, so the reading waits for the connection. |
| Authentication | A device token per approved scale. | A device token per approved scale. |
