Automating the TDAI-1120 Amp with Denon AV Receiver

General
1

After years of manually pressing the power button on my Lyngdorf TDAI-1120 amplifier, I finally found a solution to automate this process using Home Assistant (HA). The amplifier doesn’t have native HA integration, and purchasing a remote control from the manufacturer was not cost-effective. I explored various methods like power triggers and signal detection, but none worked until I stumbled upon the idea of using network commands.

Here’s how I achieved it:

  1. Adding Shell Commands: I added the following commands to my configuration.yaml file:
    yaml
    shell_command:
    tdai_on: ‘echo -ne “!SRC(6)\r” | nc 192.168.0.111 84’
    tdai_off: ‘echo -ne “!OFF\r” | nc 192.168.0.111 84’

This setup sends network commands to the amplifier. The IP address is reserved in my router’s DHCP settings for the TDAI-1120.

  1. Setting Up Automations: I created two automations—one for turning the amplifier on and another for turning it off. These automations trigger based on the state of my Denon AV receiver.

ON Automation:
yaml
alias: Turn on TDAI1120 with Denon
description: “”
triggers:

  • device_id: fc9d29d6ac95c80f010e1ace682b6c9e
    domain: media_player
    entity_id: 2864b9216395ee0a7d3f14f37c4374ff
    type: turned_on
    trigger: device
    conditions:
    actions:
  • action: shell_command.tdai_on
    metadata: {}
    data: {}
    mode: single

OFF Automation:
yaml
alias: TDAI1120 off when Denon off
description: “”
triggers:

  • device_id: fc9d29d6ac95c80f010e1ace682b6c9e
    domain: media_player
    entity_id: 2864b9216395ee0a7d3f14f37c4374ff
    type: turned_off
    trigger: device
    conditions:
    actions:
  • action: shell_command.tdai_off
    metadata: {}
    data: {}
    mode: single

This setup has transformed my home theater experience, eliminating the need for manual intervention. I hope this guide helps others facing similar challenges with their audio equipment!

Happy automating! :headphones:
