Homebridge crashes during launch with homebridge hdmi installed

[ceinem]

not sure what the error is, but after installing this addon and LibCeC and editing the config.json file, I can't get homebridge to launch. The weird thing is that there are no error messages. Homebridge launches perfectly as normal, loads all the accessories, and then simply quits. Once the plugin is removed, everything works fine again.

I had the same problem. I setup homebridge to run as a service with systemd as the homebridge user. I tracked it down to cec-client not being able to run because the homebridge user wasn't part of the video group. I followed the directions here and ran usermod -a -G video homebridge. Now homebridge starts up.

usermod: user 'homebridge' does not exist
