smart-home-nodejs: fail to change device mode or toggle

Hi, I am trying to add fan with ‘mode’ trait, but I can not change its ‘mode’ or ‘toggle’ from the simulator. For example, when I input “set my living room fan fan speed to level three”, the simulator always respond “Sorry, this action is not available in simulation”. when I input “set my living room fan oscillation on”, the simulator still respond “Sorry, this action is not available in simulation”.

But I can successfully power on/off my fan.

Here is my sync response for a fan device

            "type":"action.devices.types.DRYER",  // There is no devices type fan, so I use DRYER type instead...
