Support for Hyperion remotes.
|
|
|
|
Configuration:
|
|
|
|
To connect to [a Hyperion server](https://github.com/tvdzwan/hyperion) you
|
|
will need to add something like the following to your configuration.yaml file:
|
|
|
|
light:
|
|
platform: hyperion
|
|
host: 192.168.1.98
|
|
port: 19444
|
|
|
|
The JSON server port is 19444 by default.
