Smart device over existing toggle switch

I want to leave my existing toggle switch in place and place a smart device over it to turn it on and off.

Is there such a thing ? And compatible with the Vera?

Use any single or double z-wave relay for this application.

I prefer not to touch any wiring. Simply place the device over the toggle switch (other than a switch it) to turn it on and off.

if you are looking for a mechanical solution, then they are called fingerbots I think

There are so many good ZWave on/off in wall switches you really should consider them. Much cleaner install in the end. You preserve full stand alone switch capability plus you get ZWave controlability. Wiring is fairly simple for an on/off switch.

And compatible with the Vera?
