Convert to v2.0.0

If you want to update to v2.0.0 or higher you'll need to adjust your configuration. The reason for that is the conversion from an accessory plugin to a platform plugin.

Example config before v2.0.0:

{
    "accessory": "BenQ-Projector",
    "name": "BenQ w1070",
    "model": "W1070",
    "adapter": "/dev/ttyUSB0",
    "inputs": [
        { "input": "hdmi", "label": "Apple TV" },
        { "input": "RGB", "label": "Computer" },
        { "input": "ypbr", "label": "Component" },
        { "input": "hdmi2", "label": "Raspberry Pi" },
        { "input": "vid", "label": "Composite" },
        { "input": "svid", "label": "S-Video" }
    ],
    "baudrate": 9600
}

The same config, that works with the v2.0.0:

{
    "platform": "BenQ-Projector",
    "devices": [
        {
            "name": "BenQ w1070",
            "model": "W1070",
            "adapter": "/dev/ttyUSB0",
            "inputs": [
                { "input": "hdmi", "label": "Apple TV" },
                { "input": "RGB", "label": "Computer" },
                { "input": "ypbr", "label": "Component" },
                { "input": "hdmi2", "label": "Raspberry Pi" },
                { "input": "vid", "label": "Composite" },
                { "input": "svid", "label": "S-Video" }
            ],
            "baudrate": 9600
        }
    ]
}

In addition to the config changes, you'll need to move the plugin config from the "accessories": [...] to "platforms": [...] section of your HomeBridge instance.

Known issues

• None.

Changelog

v2.1.1

• Fix reference to current serial-io package version.

v2.1.0

v2.0.1

• Update serial-io dependency.

v2.0.0 BREAKING CHANGE

• Converted plugin to a HomeBridge Platform due to HomeKit limitations. In order to use multiple TVs in HomeKit, they need to be exposed as spearate external accessories. This feature is only available to platform plugins.

v1.1.0

• Switch from the borrowed Transport.js to serial-io package for serial communication. Should increase long term speed and stability.

v1.0.6

• Upgrade dependencies (thanks @alehaa)
• Add ability to configure baudrate (thanks @sir-bedevere)
• Add config schema for homebridge-config-ui-x support

v1.0.5:

• Stability improvements and iOS 13 fix by adding services in the correct order (thanks @AlexanderBabel).

v1.0.4:

• Fixed typo in debug logging that could cause accessory to become unresponsive.

v1.0.3:

• Fixed stability issues by reintroducing some things originally removed from Transport.js. Partially fix and partially hide performance issues by doing callbacks sooner and freeing up HomeKit sooner.

v1.0.2:

• Fixed user defined input list.

v1.0.1:

• Fixed a bug referencing package version as accessory firmware version.

v1.0:

• Initial release.
