This is how Aeon Labs operates. They make good devices and they make them on many different zwave frequencies. But they also preannounce stuff which can then take years to come to market, if it all. They’ve had some “coming soon” devices for at least four years that I know of.
There are some alternatives, depending on whether you’re in the UK or the US. See the list of buttons and remotes that work with SmartThings – – some of them work well on a wall.
