Connect a 1-Wire device

1-Wire sensors (e.g. DS18B20 temperature probes) share a single data pin on the gateway.

Protocol: 1-wire · Requires: a gateway

Connection fields:

Field Meaning
pin GPIO pin the 1-Wire bus is wired to
sampleIntervalMs How often to read (ms)

Steps

  1. Wire the sensor's data line to the chosen pin (with the required pull-up).
  2. Add a device with protocol 1-wire, pick the gateway, and set the pin + sample interval.
  3. Add a tag per reading.

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.
Why a device gets suspended
Repeated rate-limit violations suspend a device temporarily — here's the cycle.
Editing, moving, and deleting a device
Change a device's name, connection settings, gateway, or remove it.
