Can program double triple or more taps to run scenes or events, and can also sync multiple switches (wirelessly and on different circuits) to control the same lighting, or use cheaper (wired) remote switches that lack status lights, but are functionally identical.
I have single press resume previous light level, double up goes to 100% double down goes to preset dim level, triple up or down turns on/off the entire room/area of house.
Hold and release to manual dim.
That said, they do fit my bill really well and I'm almost certainly going to switch to them eventually.
You can add a zwave controller that translates ip commands from a home server to zwave commands, but it can be wired or wifi (or usb).
You can also directly program zwave "scenes", which work directly between the z wave devices without needing a controller. Like a direct remote control.
Edit: Regardless of what I meant, I think you proved I should look more into these. Thanks!
My point was that it's not like most iot devices that try to find an open internet connection to phone home. They're 100% as isolated as you want them to be.
And with a huge confession that this isn't that big of a deal.
Would also be cool if they were more "push toggle" style so that if I have two sets of switches on the same lights, I don't have to accept that four switches all in different "positions" are different states. (That is, Up Down Up Up, but all off.)
All of that said, most of that does not need any sort of "smart" additions. Basic circuitry has come a long way.
