Connect a UART / serial device

Read a serial stream from a gateway's UART pins.

Protocol: uart · Requires: a gateway

Connection fields:

Field Meaning
txPin / rxPin Gateway serial pins
baudRate Serial speed (must match the device)
dataBits / stopBits Frame format (usually 8 / 1)
parity none, even, or odd
sampleIntervalMs Read interval (ms)

Steps

  1. Cross-wire TX↔RX between the device and gateway and match the baud/parity.
  2. Add a device with protocol uart, pick the gateway, and enter the fields.
  3. Add tags for the values you parse.

uart/fault events usually mean a baud or framing mismatch.

Tags are the named measurements a device reports — what widgets bind to.
How device online/offline status works
A device is online if we've seen a message in the last 90 seconds.
Alert thresholds (and the yellow dot)
Set a high/low range on a tag; the device dot turns yellow when a reading goes out of range.
