Connect an M-Bus device

Read wired M-Bus utility meters via a gateway's M-Bus interface.

Protocol: mbus · Requires: a gateway

Connection fields:

Field Meaning
txPin / rxPin Gateway pins to the M-Bus level converter
baudRate 300, 2400, or 9600
primaryAddress The meter's M-Bus primary address
sampleIntervalMs How often to read (ms)

Steps

  1. Wire the meter through an M-Bus master/level converter to the gateway.
  2. Add a device with protocol mbus, select the gateway, and set the address + baud rate.
  3. Map meter values to tags.

mbus/fault events point to addressing or baud-rate problems.

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.
