I did this but I still don't see anything in HomeKit.
some other ideas thanks
If for some reason the device is not displayed in HomeKit app try this procedure:
Go to ./homebridge/persist.
Remove AccessoryInfo.xxx file which contain Your device data: {"displayName":"Envoy"}.
Next remove IdentifierCashe.xxx file with same name as AccessoryInfo.xxx.
Restart Homebridge and try add it to the Home app again.
