Does events: all node need an input?

Third party integrations Node-RED
1

I’ve started to create automations using HA NodeRed integration. I start with an events: all node and update the event data with something unique to capture - i.e. for a Tradfri remote control I use

{
    "device_ieee": "d0:cf:.....:b3:66"
}

I can then check the passed payload to see what buttons are pressed. All good.

As I have several old Tradfri remotes, I’m creating one sub flow to manage them but then I hit a snag - how to inject the device_ieee: into the events: all node?

Should the events: all node have an input to inject these values so that we can more readily use this in sub flows - or am I missing something?

Use a switch node after the events all node, with an empty event data, and use a JSONata expression in the switch node.

{
  "device_ieee":  $env("device_id")
}

Thanks’ @Kermit -
whilst working on this I realised that events: all doesn’t make sense to include in a sub flow. I eventually went with the following:

This keeps the filtering the event bus, but adds the specific info to the payload.

The sub flow combines all the variable parts of the remote button press event into a command string and then use switch to issue the media player commands.
