YRXV1800-MQTT

Control your Yamaha RX-V1800 via MQTT

A python3 application that enables remote control of a Yamaha RX-V1800 A/V amplifier via MQTT. The script can run on a Raspberry Pi or any similar device, which is connected to a RX-V1800 amplivier via a RS232 serial connection. YRXV1800-MQTT connects to your exisiting MQTT broker, subscribes for command topics and publishes state changes, whenever any amplifier entity state is changed (e.g., one of the amplifier's buttons is pressed). To simplify the setup, the application also supports MQTT auto discovery for HomeAssistant.

The script was tested on a Raspberry Pi running Raspian. Currently, not all RX-V1800 entities can be read or set. Use it on your own risk! The tool is provided as-is, with no guarantee that the RS232 commands work or don't damage your device.

Requirements

• Yamaha RX-V1800 A/V-Reciever
• Raspberry Pi (or similar) with RS232 interface or USB<->RS232 converter
• Python3
• Python3 library pyyaml, asyncio, pyserial-asyncio, and paho-mqtt (will be installed by this tool on startup)

Usage

Easy:

1. Clone this repository
2. Edit the config.yaml file according to your needs
3. Run python3 controller.py

As service using systemd:

1. Same as Easy, but don't run manually.
2. Edit file systemd/yrxv1800-mqtt.service and change working directory and file path of controller.py to your needs (defaults to /srv/yrxv1800-mqtt/controller.py)
3. Link and enable systemd config:

sudo ln -s /srv/yrxv1800-mqtt/systemd/yrxv1800-mqtt.service /etc/systemd/system/yrxv1800-mqtt.service
sudo systemctl daemon-reload
sudo systemctl enable yrxv1800-mqtt.service
sudo systemctl start yrxv1800-mqtt.service

4. Verify service status sudo systemctl status yrxv1800-mqtt.service

Integration into HomeAssistant

MQTT enables easy integration in any HomeAssistant instance, which makes automation and remote control even smarter. Simply configure MQTT in HomeAssistant and enable MQTT auto discovery.

Note: Minimum HomeAssistant Version 2021.6 required!
