Sudo homebridge doesn't work

[Will711990]

Hi,

I need your help !!
I wanna configure my Dash Button... so I installed homebridge-dash.
When I right Homebridge, I work nicely but I can't use my Dash Button, because I need of user's rights.

And when I write sudo homebridge it tells me there is a mistake in my config.json file. But there isn't because it works without sudo !!!

I'm on PRi 3 and I can't find solution and I don't understand...
Do you have a solution because I don't understand : Run Homebridge with elevated privileges...

thank you !

I strugled with same problem. Homebridge worked perfectly with other plugins like - wemo - ifttt. After adding plugin homebridge-dash its suddenly hangs on. I realized that there is problem with privileges. The thing that helped me is -

edit file homebridge.service

sudo nano /etc/systemd/system/homebridge.service

Change User=pi to User=root

[Unit]
Description=Node.js HomeKit Server
After=syslog.target

[Service]
Type=simple
User=pi
EnvironmentFile=/etc/default/homebridge
ExecStart=/usr/lib/node_modules/homebridge/bin/homebridge $HOMEBRIDGE_OPTS
RestartSec=10
KillMode=process

[Install]
WantedBy=multi-user.target

I hope it helps you!
