Learn RF not working
I have multiple Broadlink RM devices and the UDP doesn't seem to be working on my network so I have to use the learn-code function.  I'm trying to grab the RF codes off of my Broadcom RM3 Pro Plus.  Below is my config code.  

```
                {
                    "accessory": "Broadlink RM Learner",
                    "name": "Learn RF",
                    "type": "learn-code",
                    "scanFrequency": true,
                    "host": "192.168.7.188"
                },
```
It comes back with  showing that it found a frequency but it never prints out the results.

```
 [Broadlink RM] [ACTION] Hold down the button that sends the RF frequency.
 [Broadlink RM] [INFO] Scan RF (found frequency - 1 of 2)
 [Broadlink RM] [INFO] Scan RF (stopped - 20s timeout)
 [Broadlink RM] [INFO] Scan RF (stopped)
```
I've heard that you need to switch on the learn IR but when I have this custom learn-button it doesn't seem to provide the default buttons.  Is there a way to work around this?
