This driver should work: [DRIVER] Zooz Smart Plugs Advanced (ZEN04, ZEN05, ZEN14, ZEN15, ZEN20, ZEN25)
Use the STANDARD driver, it is setup to handle multiple endpoints like with the ZEN14 outdoor double plug. When you run the Configure command It should create two child devices where you can control each plug individually.
The ZEN25 has power metering on both endpoints so its more specialized, so do not use that driver.
I also have in the plans to add a plugs driver to my universal set which will be able to scan your device for settings along with all the features of the Zooz plugs driver. Looks like that just became a priority! So stay tuned over here for updates (mark thread as watched if you want): [DRIVER] Universal Z-Wave Drivers (Switch/Dimmer)
Yay for new z-wave devices!!!
PS - Ignore the warning about having an unknown device, it will not cause any harm it is just letting people know why there are no settings exposed, for when they inevitably select the wrong driver for a Zooz product.
