2 Broadlink RM3 Pro Plus, only 1 learn/scan button in Home app
So i'm seeing both devices show up in the logs: 

```
[2018-4-3 17:44:35] [Broadlink RM] [INFO] Discovered Broadlink RM3 Pro Plus (279d) at ip_address (mac_address)
[2018-4-3 17:44:35] [Broadlink RM] [INFO] Discovered Broadlink RM3 Pro Plus (279d) at ip_address (mac_address)
[2018-4-3 17:44:36] [Broadlink RM
```

BUT when I go in to the home app and look at the homebridge, and I see "accessories" I only see the one. 

The new one I just added can't receive/learn signals. 

It would be nice to have both remotes show up. Also it would be nice to be able to "name" them so the `hosts` key could be `livingroom` instead of an ip address.
