Adapter creating data points as Type Button, not as indicator.state

[Th301]

I installed the fakeroku adapter in my io-Broker. Setting it up worked normal, I would say.
My Harmony-Hub found the device and I could add it to the activities.

In io-Broker, the adapter created below the folder "keys" the possible keys to use. The problem is, that they are creates as the type "Button" and not as "indicator.state" like I saw it in forums. Now, I can not really use this as a trigger for blockly. Is this a bug or wanted behavior? What can I do to only see "true" when the button is pushed and "false" if not?
