My Home Assistant customisations

rotel_rsp1570

This is a media player custom component that can control a Rotel RSP-1570 processor

The component utilises the rsp1570serial library on PyPi for communications with the device

Configuration

Take a look at configuration.yaml and groups.yaml in the .homeassistant folder for usage examples.

Here is a basic example of the configuration.yaml entry needed:

media_player:
- platform: rotel_rsp1570
  device: /dev/ttyUSB0
  source_map:
    CATV: VIDEO 1
    NMT: VIDEO 2
    APPLE TV: VIDEO 3
    FIRE TV: VIDEO 4
    BLU RAY: VIDEO 5

Obviously the device parameter needs to match your own environment. Some examples might be:

• /dev/ttyUSB0 (Linux)
• COM3 (Windows)
• socket://192.168.0.100:50000 (if you are using a TCP/IP to serial converter)

The keys in source_map should ideally exactly match the source names for any inputs that have custom names.

The sample configuration file also demonstrates how to access the granular state of the device via template sensor and binary template sensor elements.

Note that the state of the media player component is set by messages received from the device.

• When you start Home Assistant it is assumed that the device is turned off. If that isn't the case then any device activity will be enough for the component to align with the device. If you click the POWER_ON button and the device is already on then that will be enough for the component to work it out.
• If the device state is changed externally (perhaps by the remote) then Home Assistant will keep in sync with it.

If you want to see a bit more about what's going on then add the following to configuration.yaml

logger:
  default: info
  logs:
    custom_components.rotel_rsp1570.media_player: debug

Infra Red Control

My Raspberry Pi has an IR Hat so I can use lirc to trigger Home Assistant automations.

I chose a random remote control from the lirc remotes database and then configured my Harmony Hub with the same device. Now I can use this fake remote to control Home Assistant as part of a Harmony activity.

Please see .lircrc and automations.yaml for my PoC configuration. Plus, you need to add the following into your configuration.yaml file:

lirc:
