Numato

Version: 2.0

Introduction

This module adds support for certain Numato relay modules, such as the 16 Channel USB Relay Module and the 32 Channel USB Relay Module.

Usage

Each configured device generates one binary node per relay. The node id is <device id>/<relay index>, with the relay index starting at 0. For the example configuration, this leads to RB/0, RB/1, etc.

Device configuration

This module follows the standard definition of devices. In addition to the standard properties of a device, it requires the following.

• address (string, required) – The address of the device, such as /dev/tty.usbmodem1101 or COM3. This is the serial number of the device, which can be found on the back of the device. This is a required field.
• model (string, required) – The device model; only relayboard is permitted.
• relay_count (integer, required) – The number of relays.

An example is shown below.

devices:
  - id: RB
    label: Relay board
    kind: relayboard
    address: /dev/tty.usbmodem1101
    relay_count: 32
