How to debug ZWAVE events in hass.buss?

Hi,

I need to somehow debug what is happening in communication between my ZWAVE danfoss thermostat and the controller to capture events and use them later.

I imported constants like this:

from homeassistant.components.zwave.const import (
    EVENT_SCENE_ACTIVATED, DATA_DEVICES, EVENT_NETWORK_COMPLETE, EVENT_NODE_EVENT,
    SERVICE_REFRESH_NODE_VALUE, DATA_NETWORK, COMMAND_CLASS_INDICATOR, EVENT_NETWORK_READY,
    EVENT_NETWORK_COMPLETE_SOME_DEAD)

then in python custom_components script I am set up listener:

hass.bus.listen(EVENT_NODE_EVENT, event_listener)

and printing like this:

def event_listener(event):
        _LOGGER.error('Captured event %s' % event)

however problem is that log does not show any ZWAVE event even when I trigger some action that are sucessfuly completed and thermostat value is set to Danfoss.

Any ideas why this is not working ?

Thanks
