Arcam FMJ Receivers

The arcam_fmj integration allows you to control Arcam FMJ Receivers from Home Assistant.

Supported devices:

  • AVR 380
  • AVR 450
  • AVR 750
  • Likely other AVRs


Menu: Configuration -> Integrations.

Click on the + sign to add an integration and click on Arcam FMJ. Follow the configuration flow, after finishing, the receivers will be available.

Power state

Arcam FMJ receivers turn off their network port when in standby, the component will try to reconnect to the receiver every 5 seconds. This mean powering on the first zone is not possible over the builtin network connection. Two options for complete power control exists: IR or Serial gateway.

IR command

Use an IR blaster to send a command to turn the device on using these discrete codes:

  • Zone 1: Protocol: RC5 Device: 16 Function: 123
  • Zone 2: Protocol: RC5 Device: 23 Function: 123

Turn on sometime requires two IR codes to be sent. You can generate the raw, broadlink or other IR format string using irgen tool like:

irgen -i rc5 -d 16 0 123 -o broadlink_base64 -r 2

To trigger this IR command add an automation on the event arcam.turn_on filtering on the entity_id of the media_player zone entity. This can be added using device automations or manually using normal automations.

Serial Port to network gateway

Use a network to a serial port gateway to connect to the serial port of the receiver. The serial port is always available and can power on the device. This is the most reliable communication method as well.
