Scan this code with your HomeKit App on your iOS device to pair with Homebridge:

what should be the folder where the plugins are installed ? Do I need to move them ?

npm -v
2.15.5

node -v
v4.4.5

FOUND THE PROBLEM !!

i have copied the plugins to the folder where homebridge is searching for plugins

sudo cp -a /home/pi/node_modules/"plugin that installed" /usr/local/lib/node_modules

If your using systemd, and these instructions

It would go in the file /etc/default/homebridge, to the “HOMEBRIDGE_OPTS” line
