Great info! I took your findings and put together an AppDaemon app.
import appdaemon.plugins.hass.hassapi as hass
#
#
# SETUP
# https://community.home-assistant.io/t/ge-14294-and-jasco-equivilant-zwave-dimmer-double-tap-event-on-associaton-group-3-need-config-help/29469/17
#
# Forward double-tap events to your controller. In the Z-Wave configuration panel of HA:
# Select the node for the light switch you want to enable double-tap on.
# Under Node group associations select Group 3.
# Under Node to control select your Z-Wave USB stick (or whatever Z-Wave controller you use).
# Hit Add to Group
#
#
# Args:
# entities:
# - entity: Zwave entity to monitor for double tap.
# events:
# - tap_up: List of actions to fire on double tap up.
# - action_entity: Entity to perform action on. Ex: light.living_room_light
# action: Action to perform. 'on' or 'off'
# - tap_down: List of actions to fire on double tap down.
# - action_entity: Entity to perform action on. Ex: light.living_room_light
# action: Action to perform. 'on' or 'off'
#
# NOTE: the triggering entity does not turn on by default and will need to be added as an action_entity if you would like it to.
#

In its current state this supports domains that work with the turn_on/turn_off service.
UPDATE: Support for stepping fan speed.
Requires utils.py with the following functions:
class utils(hass.Hass):
def initialize(self):
self.log("initialized utils")
def increment_fan_speed(self, fan_speed):
"""
Increment fan speed one step.
"""
return {
'off': 'low',
'low': 'medium',
'medium': 'high'
}.get(fan_speed, 'high')
def decrement_fan_speed(self, fan_speed):
"""
Decrement fan speed one step.
"""
return {
'high': 'medium',
'medium': 'low',
'low': 'off'
}.get(fan_speed, 'off')
and an updated apps.yaml entry:
