This stylish switch from TKBHome is designed to switch 2 independent sets of lights or loads of up to 6A each, as this is the first TKB wall switch to have dual relays - so both the left and right paddles contain separate relays/loads.
The switch is designed to be a direct replacement for an existing double light switch and is a simple way to add Z-Wave control to your lighting circuits.
The switch is equipped with a neat LED indicator to help you locate it in a dark room (can be turned off via Z-Wave parameters)
The key thing to note, for UK consumers, is that this switch requires a neutral at the switch (3 wire system) which is less common in older UK wiring set-ups. If in doubt, please check with an electrician before purchasing.
The switch has the latest Z-Wave Plus chip, meaning it improves communication with your other Z-Wave devices and as it's a mains powered device it will act as a Z-Wave repeater to strengthen your network.
This switch should work with all major Z-Wave gateways and controllers. TKBHome have verified support for:

Not bad (but not zwave compliant?)

Using this device with an Aeotech Z-stick, I found that if I remote operated the switch a couple of times in quick succession, or attempted to remote operate both switches (i.e. setting a scene) I'd get ~10 second delays.
I've spent a few days investigating this. The issue is that when the switch receives a "Binary Switch Set" command, it immediately returns a "Binary Switch Report", before this report is requested by the controller. This seems to result in crossed wires, and a timeout error.
I fixed this in my case by telling the controller that the switch does *not* respond to BinarySwitch_Get. The controller still receives the state of the switch when it is flipped (remotely or locally), and it seems to work fine now.
