“Works great. Easy to connect with the Smartthings hub. There is no problem with connectivity, even that I didn't connect to the main source but works only on batteries. At the beginning I had some problems with the "device handler", when I added it to the ST, the device was shown as: generic z-wave and the list of devices didn't even show the fibaro walli controler, there were others but exactly this model was not there (but it was a few weeks ago). But fortunately it works now and I am personally satisfied. And good news if you want to replace ordinary (not smart) wall switch, they fit perfectly and when installed they look like ordinary switches. (ok maybe some screw holes are not as they should be but there is no problem to screw them as they should be).”
“Easy to set up and use. Provides two buttons each of which can be pressed once, twice or three times or held down and released giving a total of 10 different actions/scenes. Can also be used to control a shutter or blind although I haven’t tried this. Has an internal battery and can be used with an external power supply if desired. Screw mounted (which I prefer to having sticky pads).”
