Error after installing "homebridge-smartthings"
Without `homebridge-smartthings`, I could launch homebridge and register it with home app iOS, however there is no device found after adding the accessory.

So I was thinking if it has anything to do with `homebridge-smartthings` installation. So if I install it, I got this error when running `homebridge`:
