 Use an IR blaster to send a command to turn the device on using these discrete codes:
 
- - Zone 1: Protocol: NEC1 Device: 16 Function: 123
- - Zone 2: Protocol: NEC1 Device: 23 Function: 123
+ - 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](https://github.com/elupus/irgen) tool like: 
+
+```shell
+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.
