There is no service for VARIABLE:undefined
Hi,

I'm trying to add a systems variable to homebridge my configuration looks like this:

"platforms": [
    {
      "platform": "HomeMatic",
      "name": "Homatic CCU",
      "ccu_ip": "x.x.x.x",
...
     "variables":["Anwesenheit"]
}]}

When I'm starting homebridge I'm getting a message

[Homatic CCU] There is no service for VARIABLE:undefined

and I can't see the variable in Eve or Home app. (I'm expecting it to show up as switch). Homematic Plugin Version is 0.0.56

Any clues?

Thx
Chris
