I did a reinstall as mentioned in the post. Homebridge starts and i see all the switches.

But when i switch nothing happens. Need to look into this issue. Any suggestions welcome.
Thanks for your help...

Thanks, i followed the instructions and node -v and npm -v both work. But when running homebridge i get this result: Any ideas? pi@raspberrypi:~$ homebridge /usr/lib/node_modules/homebridge/node_modules/hap-nodejs/node_modules/mdns/lib/dns_sd.js:35 throw ex; ^ Error: Module version mismatch ...

I just installed Domoticz from the SD card image "domoticz-raspberrypi-sdcard-4834.7z"
Domoticz runs smooth, but as i want to run homebridge i get a segmentation fault. Also on running npm -v or node -v.

Any help welcome. Thanks...
