    i have just installed it in the uk, with 2 wire system and it works through the app, but the switching method doesn't work. i'm an electrician and know it is wired 100% correct.

    i have 230v coming in but when testing at the "com" im only getting 130v. shouldn't this be 230v? and would that explain why the switching isn't working

    I installed this IN THE FIXTURE and then I leave the wall switch turned on (unless I forget). In the fixture I have a 3-wire install with no issues. Can be a bit tight, and because of all the metal I try to have the antenna sticking out…but barely noticeable. Works great. If I forget and turn the switch off, as soon as I turn it back on it remembers where it is supposed to be after a moment.

    How exactly does the dimmer work in combination with the wall switch – can the switch turn the light on and then the light be turned off by z wave? In other words, can z wave turn the light off by overriding the manual switch in the on position?
