DMX

Requirements

This plugin needs one of the supported DMX interfaces:

NanoDMX
DMXking it should work with other Enttec Pro compatible as well.

The communication with the interface is handled via serial interface. Thus Python serial driver is need as well. A requirements file is provided to easy the installation.

Configuration

plugin.yaml

dmx:
    plugin_name: dmx
    serialport: /dev/usbtty...
    # interface = nanodmx

With interface it can be chosen between nanodmx and enttec. By default nanodmx is used.

The serialport must match the real interface. On Linux it might be necessary to create a udev rule. For a NanoDMX device provided via /dev/usbtty-1-2.4 the following udev rule could match:

# /etc/udev/rules.d/80-smarthome.rules
SUBSYSTEMS=="usb",KERNEL=="ttyACM*",ATTRS{product}=="NanoDMX Interface",SYMLINK+="usbtty-%b"

Please consult the online help for Linux on how to properly create udev rules.

items.yaml

dmx_ch

With this attribute one or more DMX channels given as integer can be specified

Example

living_room:

    dimlight:
        type: num
        dmx_ch:
          - 10
          - 11

    dimlight_reading:
        type: num
        dmx_ch: 23

In a logic an expression like sh.living_room.dimlight(80) will send 80 to channels 10 and 11 to dim the living room light as sh.living_room.dimlightreading(50) will send 50 to channel 23 to dim the living room reading light.

Methods

send(channel, value)

Sends the value to the given dmx channel. The value may be in range from 0 to 255.

Example: sh.dmx.send(12, 255) will send the value 255 to channel 12
