Title: Works great as one-way switch
Review: Works phantastic as a 1-way switch. But there are some minor issues when replacing a 3-way switch: There is an older and a newer version of the switch, but unfortunately the installation instructions were not updated and are not complete (when it comes to replacing a 3-way switch). Luckily the manufacturer's customer service quickly provided me with the instructions. However, I still couldn't get it to work the way it is supposed to (as many others according to some other internet forum). In my case the remaining conventional 3-way switch cannot trigger the light to come on which is fine as the sensor field is so big that it is no longer needed. If your 2 conventional 3-way switches are far apart from each other you can replace both by a Pir sensor switch.
Is the review positive or negative?
