Light switches that only send signal to Smart things

[Rockrabbit (Isaac Katzav)]

Hi I am looking to install light switch that only send signal to Smart things so it can control another lights as slave.
I know about the master slave set but only have neutral where the master is. So technically looking to put a slave where the current slave is but with no wires. Batteries operated?

Is there a product like that?

If not any simple push buttons you recommend.

Assuming you’re in the US The one most like a regular wall switch is the battery operated Cooper 9540, but there are a number of possibilities.

FAQ: Full list of buttons and remotes confirmed to work with SmartThings [Not all devices listed work with the 2020 Platform]

I’d like to know which buttons and remotes are currently supported or might be supported in the future. Ideally, I’d like to find something similar to the following: http://www.evolvecontrols.com/devices/control-devices/glass-series Though alternatively just a simple nice-looking button which actually works unlike this Aeon according to Amazon reviews: http://www.amazon.com/Touch-Panel-Button-Switch-AL-001/dp/B00GL6B4GG/ref=sr_1_3?s=hi&ie=UTF8&qid=1421468320&sr=1-3&keywords=aeon+button There is an Aeon Key Fob as well, but it doesn’t seem to be very durable or stylish: What else is available?
