# Monoprice Whole House Audio Binding
This binding can be used to control a Monoprice MPR-SG6Z (10761), Monoprice Passive Matrix (39261) & Dayton Audio DAX66 whole house multi-zone amplifier system. All amplifier functions available through the serial port interface can be controlled by the binding. Up to 18 zones can be controlled when 3 amps 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 a serial port on the server side, you can use a USB to serial adapter.
You don't need to have your whole house amplifier device directly connected to your openHAB server. Some newer versions of the amplifier have a built-in ethernet port that supports serial over IP. Or you can connect it for example to a Raspberry Pi and use ser2net Linux tool (opens new window) to make the serial connection available on the 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 amplifier or serial over IP device | Host name or IP |
Port | port | Communication port (default 8080 for newer amps with built-in 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 amplifier 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 thedialout
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 8080 using ser2net Linux tool (opens new window):
8080:raw:0:/dev/ttyUSB0:9600 8DATABITS NONE 1STOPBIT LOCAL
