HomeAssistant: remote not populating

In HomeAssistant, I have a Broadlink RM4 Pro. I have several commands that I've saved and those work in HomeAssistant. I am hoping to bring this remote into myServer so that I can send the same remote.send_command calls from myserver that I can from HomeAssistant. However, I'm not seeing the broadlink device populate in myserver. How can I add this device?

Nevermind, I was able to figure this out. Host:Discover didn't do anything in this case. I had to do RemoveDevices, then another discover.

Ok I have this added, however now I could use some help actually using it. This is currently listed as a Control device. In HomeAssistant, using Developer Tools, I am sending this:

Is there a way to make myServer send this?

Here is the HomeAssistant YAML if that helps:

service: remote.send_command
target:
device_id:
- 1bce0eab1bab833c89e0cfc52cbdfd39
data:
num_repeats: 1
delay_secs: 0.4
hold_secs: 0
command: Down
device: Projector Lift

I also have these added to a HomeAssistant script, so I will test and see if there's a way I can just call that instead. Update: Not seeing a way to trigger Home Assistant scripts either

SUCCESS! Ok this was a bit complicated, but here's what I got to work.

1. I added the RM4 Pro in HomeAssistant.
2. In HomeAssistant, I added the Remote commands I wanted
3. I created HomeAssistant scripts that executed the commands I wanted in the order I wanted
4. I created HomeAssistant Automations for each script that had a Webhook trigger
5. In myServer, I created Macros that looked like this:

Macro|
Run|curl~-X POST http://{myHomeAssistantIP}:8123/api/webhook/{myWebhookId}!
//!
// fini

Ok, so, the Broadlink device is an IR / RF hub?
And, historically you were able to control devices managed by Broadlink by sending commands via a HomeAssistant user interface?
And, with the integration, you figured out how for myServer to send to HomeAssistant to send to Broadlink?
How is the response time on command execution?

Do you expect to use the SmartRemote to send commands too?

Neat.  Nice discovery!

I added your script to the HAGateway driver documentation for others to find.  Thanx!
So now, RF devices are supported via SmartRemote / myServer.
