Connect an I²C device

I²C sensors share two lines (SDA/SCL) on the gateway.

Protocol: i2c · Requires: a gateway

Connection fields:

Field Meaning
sdaPin / sclPin I²C data and clock pins
clockHz Bus clock (e.g. 100000, 400000)
sampleIntervalMs Read interval (ms)

Steps

  1. Wire SDA/SCL (with pull-ups) to the gateway pins.
  2. Add a device with protocol i2c, pick the gateway, and set the pins + clock.
  3. Add a tag per measurement the sensor exposes.

i2c/fault events usually mean a wrong address, missing pull-ups, or a clock too fast for the wiring.

Device parameters (tags) explained
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.
