You only need a drill and a screwdriver to install Nobi. Simply replace the existing pendant lamp with Nobi, as you would any other lamp. The only other thing you need to do is fix a little block behind the light switch so that Nobi remains connected to the electricity at all times. This allows you to switch the light on and off, just like you would ordinarily, without shutting off the fall detection feature.
To make the Nobi lamp functional, you need electricity and a working WiFi connection.
