pimatic-denon-avr

Pimatic plugin to monitor & control a Denon AV Receiver over a network connection.

Status of Implementation

Since the first release the following features have been implemented:

• support for power switching, mute, volume control, input selection, and status display
• support for zone control (up to three zones depending on receiver model)
• auto-discovery for pimatic 0.9
• HTTP transport as an alternative to using telnet for recent AVR models
• action to select input source, devices for power switching, volume mute, volume control are "switch" or "dimmer" devices types and support the respective action operations

Additional features can be added easily and I am happy to do this on demand.

Notable Changes

Since version 0.9.1 changing the master volume automatically switched on the AVR. Unfortunately, it turned out that this causes an disruption of video processing with some receivers. Therefore, as of version v0.9.4 changing the master volume will no longer switch the AVR.

Since version 0.9.7 the minimum interval time for updates has been lowered to 2 seconds. Note, however, shorter update cycles may result in higher load an memory consumption on the pimatic host. It may also degrade the performance of AVR's control system which provides the web & mobile applications access.

Plugin Configuration

Note, the control protocol is set to TELNET by default. The telnet control is limited to one control application connection at a time, as the AVR only accepts a single transport connection. Use the HTTP control protocol instead if you have a '11, '12, '13, or X series AVR or a newer model released since 2014.

{
      "plugin": "denon-avr",
      "host": "avr.fritz.box",
}

The plugin has the following configuration properties:

Property	Default	Type	Description
host	-	String	Hostname or IP address of the AVR
port	23 or 80	Number	AVR control port - only required for testing
protocol	"TELNET"	Enum	The protocol to be used, one of "HTTP" or "TELNET"
debug	false	Boolean	Debug mode. Writes debug messages to the pimatic log, if set to true

Device Configuration

The following devices can be used. Each device will query the AVR for the status updates at regular time intervals. The default is 60 seconds. Note, the AVR will only accept a single connection to the control port. Shorter intervals may keep the connection open forever and may block other applications, e.g. remote control applications for the smart phone. If another application occupies the control port forever the status cannot be updated and commands will result in 'timeout' errors.

You may realize some strange behaviour like switches or sliders flipping back to their previous position. This is due to the behaviour of the AVR control system. When the AVR is in STANDBY it does not allow changing settings like volume, mute, input and will reply with its currently status parameters.

If the power on command is sent to the AVR, it will take up to 2 seconds for the AVR control system to transition to the power on state and to accept changing settings. Thus, subsequent commands will be deferred by 2 seconds. You may realize this, for example, if you change the volume immediately after switching power on, it will take 2 seconds for the volume attribute to update. In rare cases, if the power on procedure takes longer, the slider may flip back to its previous position.

DenonAvrPresenceSensor

The Presence Sensor presents the power status of the receiver and provides information about the master volume and selected input source.

The following predicates and actions are supported:

• {device} is present|absent

DenonAvrPowerSwitch

The Power Switch can be used to switch the AVR on or off (standby) mode. Depending on your AVR configuration you may not be able to switch it on again. See the AVR manual for details.

The following predicates and actions are supported:

• {device} is turned on|off
• switch {device} on|off
• toggle {device}

DenonAvrZoneSwitch

The Zone Switch can be used to switch a zone of the AVR on or off if multiple zones are supported and setup for the receiver. See the AVR manual for details.

{
      "id": "avr-2",
      "name": "AVR Zone 2",
      "class": "DenonAvrZoneSwitch"
      "zone": "ZONE2"
}

The device has the following configuration properties:

zone	"MAIN"	Enum	The zone to be switched on and off, one of "MAIN", "ZONE2", or "ZONE3"
interval	60	Number	The time interval in seconds (minimum 2) at which the zone switch state of the AVR will be read

The following predicates and actions are supported:

• {device} is turned on|off

DenonAvrMuteSwitch

The Mute Switch can be used to mute or un-mute the master volume.

DenonAvrMasterVolume

The Master Volume can be used to change the absolute master volume. This device can only be used with AVRs which support absolute volume control on a scale from 0-98. As some AVRs already stop at a lower maximum volume the maxAbsoluteVolume property is provided (see properties table below).

{
      "id": "avr-4",

volumeLimit	0	Number	If greater than 0, enforce a volume limiter for the maximum volume level
maxAbsoluteVolume	99	Number	Maximum absolute volume which can be set. Some receivers already stop at a lower value than 99

The following predicates and actions are supported:

      "class": "DenonAvrInputSelector"
      "buttons": [
