Dyson pure cool platform plugin not showing fan in homekit
Hi,

I am trying to setup my dyson fan in HomeKit via hoobs.  I am using the Dyson purecool platform.  I have put in the required details, but nothing shows up.  I have only added a few devices in Hoobs, but they all shown up.  In the log section it stats ‘ [DysonPureCoolPlatform] Got devices from config’. Can’t see any error messages. 

**Expected behavoir**
Fan should be showing up in HomeKit 

**Plugin name**
Dyson purecool platform
