This binding connects Roku streaming media players and Roku TVs to openHAB.
The Roku device must support the Roku ECP protocol REST API.
In order for the binding to control the Roku, the following setting:
**Settings-> System-> Advanced system settings-> Control by mobile apps**
must be configured as `Enabled` or `Permissive`.
## Supported Things
There are two supported thing types, which represent either a standalone Roku device or a Roku TV.
