Entity "homematic.wireless" - what's it for?

Configuration
1

I have my homematic devices bound to HASS using Homegear as a CCU replacement. The configuration is quite simple:

homematic:
   hosts:
       wireless:
         ip: 127.0.0.1
         primary: true

That obviously created an entity “homematic.wireless” showing up in my UI. Anybody knows what’s it good for? Here are the state attributes:

{
  "friendly_name": "wireless",
  "icon": "mdi:gradient"
}

I think you need this device to read and write variables. https://community.home-assistant.io/t/homematic-modul-read-write-system-variables/3577/6

Since I’m part of the team which developed the HomeMatic component for HASS:
@mrMuppet is right, it’s used to access the system variables of the CCU / Homegear. Furthermore it also has an attribute for the “Systemmeldungen”. So when there’s been a communication error or the case of a shutter contact has been opened (sabotage detection), then HASS can read that with a Template Sensor. Although in this case just the sum, not the individual messages. But at least this is enough to get you notified is something is wrong with your system.

Okay, thanks for the explanation.
