# Monoprice Whole House Audio Binding

This binding can be used to control the Monoprice MPR-SG6Z (10761) or Dayton Audio DAX66 whole house multi-zone amplifier. All controller functions available through the serial port interface can be controlled by the binding. Up to 18 zones can be controlled when 3 amplifiers are connected together (if not all zones on the amp are used they can be excluded via configuration). Activating the 'Page All Zones' feature can only be done through the +12v trigger input on the back of the amplifier.

The binding supports two different kinds of connections:

  • serial connection,
  • serial over IP connection

For users without serial connector on the server side, you can add a serial to USB adapter.

You don't need to have your Monoprice whole house amplifier device directly connected to your openHAB server. You can connect it for example to a Raspberry Pi and use ser2net Linux tool to make the serial connection available on LAN (serial over IP).

# Supported Things

There is exactly one supported thing type, which represents the amplifier controller. It has the amplifier id.

# Discovery

Discovery is not supported. You have to add all things manually.

# Binding Configuration

There are no overall binding configuration settings that need to be set. All settings are through thing configuration parameters.

# Thing Configuration

The thing has the following configuration parameters:

Parameter Label Parameter ID Description Accepted values
Serial Port serialPort Serial port to use for connecting to the Monoprice whole house amplifier device Serial port name
Address host Host name or IP address of the machine connected to the Monoprice whole house amplifier device (serial over IP) Host name or IP
Port port Communication port (serial over IP). TCP port number
Number of Zones numZones (Optional) Number of amplifier zones to utilize in the binding (up to 18 zones with 3 amplifiers connected together) 1-18; default 6
Polling Interval pollingInterval (Optional) Configures how often (in seconds) to poll the controller to check for zone updates 5-60; default 15
Ignore Zones ignoreZones (Optional) A comma seperated list of Zone numbers that will ignore the 'All Zone' (except All Off) commands ie: "1,6,10"
Initial All Volume initialAllVolume (Optional) When 'All' zones are activated, the volume will reset to this value to prevent excessive blaring of sound 😉 1-30; default 10
Source 1 Input Label inputLabel1 (Optional) Friendly name for the input source to be displayed in the UI (ie: Chromecast, Radio, CD, etc.) (default "Source 1") A free text name
Source 2 Input Label inputLabel2 (Optional) Friendly name for the input source to be displayed in the UI (ie: Chromecast, Radio, CD, etc.) (default "Source 2") A free text name
Source 3 Input Label inputLabel3 (Optional) Friendly name for the input source to be displayed in the UI (ie: Chromecast, Radio, CD, etc.) (default "Source 3") A free text name
Source 4 Input Label inputLabel4 (Optional) Friendly name for the input source to be displayed in the UI (ie: Chromecast, Radio, CD, etc.) (default "Source 4") A free text name
Source 5 Input Label inputLabel5 (Optional) Friendly name for the input source to be displayed in the UI (ie: Chromecast, Radio, CD, etc.) (default "Source 5") A free text name
Source 6 Input Label inputLabel6 (Optional) Friendly name for the input source to be displayed in the UI (ie: Chromecast, Radio, CD, etc.) (default "Source 6") A free text name

Some notes:

  • On Linux, you may get an error stating the serial port cannot be opened when the MonopriceAudio binding tries to load.
  • You can get around this by adding the openhab user to the dialout group like this: usermod -a -G dialout openhab.
  • Also on Linux you may have issues with the USB if using two serial USB devices e.g. MonopriceAudio and RFXcom.
  • See the general documentation about serial port configuration for more on symlinking the USB ports.
  • Here is an example of ser2net.conf you can use to share your serial port /dev/ttyUSB0 on IP port 4444 using ser2net Linux tool (take care, the baud rate is specific to the Monoprice amplifier):
4444:raw:0:/dev/ttyUSB0:9600 8DATABITS NONE 1STOPBIT LOCAL

# Channels

The following channels are available:

Channel ID Item Type Description
all#allpower Switch Turn all zones on or off simultaneously (those specified by the ignoreZones config option will not turn on)
all#allsource Number Select the input source for all zones simultaneously (1-6) (except ignoreZones)
all#allvolume Dimmer Control the volume for all zones simultaneously (0-100%) [translates to 0-38] (except ignoreZones)
all#allmute Switch Mute or unmute all zones simultaneously (except ignoreZones)
zoneN#power (where N= 1-18) Switch Turn the power for a zone on or off
zoneN#source (where N= 1-18) Number Select the input source for a zone (1-6)
zoneN#volume (where N= 1-18) Dimmer Control the volume for a zone (0-100%) [translates to 0-38]
zoneN#mute (where N= 1-18) Switch Mute or unmute a zone
zoneN#treble (where N= 1-18) Number Adjust the treble control for a zone (-7 to 7) -7=none, 0=flat, 7=full
zoneN#bass (where N= 1-18) Number Adjust the bass control for a zone (-7 to 7) -7=none, 0=flat, 7=full
zoneN#balance (where N= 1-18) Number Adjust the balance control for a zone (-10 to 10) -10=left, 0=center, 10=right
zoneN#dnd (where N= 1-18) Switch Turn on or off the Do Not Disturb for the zone (for when the controller's external page trigger is activated)
zoneN#page (where N= 1-18) Contact Indicates if the page input is activated for the zone
zoneN#keypad (where N= 1-18) Contact Indicates if the physical keypad is attached to a zone
