# AmpliPi Binding
This binding supports the multi-room audio system AmpliPi (opens new window) from MicroNova (opens new window).
# Supported Things
The AmpliPi itself is modeled as a Bridge of type controller.
Every available zone as well as group is managed as an individual Thing of type zone resp. group.
# Discovery
The AmpliPi announces itself through mDNS, so that the bindings is able to find it automatically.
As soon as the AmpliPi is online, its zones and groups are automatically retrieved and added as Things to the Inbox.
# Thing Configuration
The controller Bridge has two configuration parameters:
| Parameter | Required | Description |
|---|---|---|
| hostname | yes | The hostname or IP address of the AmpliPi on the network |
| refreshInterval | no | The time to wait between two polling requests for receiving state updates. Defaults to 10 seconds. |
Both the zone and group Things only require a single configuration parameter id, which corresponds to their id on the AmpliPi.
# Channels
These are the channels of the controller Bridge:
| Channel | Type | Description |
|---|---|---|
| preset | Number | Allows setting a pre-configured preset. The available options are dynamically read from the AmpliPi. |
| input1 | String | The selected input of source 1 |
| input2 | String | The selected input of source 2 |
| input3 | String | The selected input of source 3 |
| input4 | String | The selected input of source 4 |
The zone and group Things have the following channels:
| Channel | Type | Description |
|---|---|---|
| volume | Dimmer | The volume of the zone/group |
| mute | Switch | Mutes the zone/group |
| source | Number | The source (1-4) that this zone/group is playing |
# Audio Sink
For every AmpliPi controller, an audio sink is registered with the id of the thing. This audio sink accepts urls and audio files to be played. It uses the AmpliPi's PA feature for announcements on all available zones. If no volume value is passed, the current volume of each zone is used, otherwise the provided volume is temporarily set on all zones for the announcement.
