No accessory created
Hello, 
I tried to use this plugin in Homebridge, but no accessory created.
I check and every information of the device is visible in the log, I can see : 
Adding: Temperature Humidity Sensor (wsdcg / xxxxxxxxxxxxxx)
Adding: Multi-mode Gateway (wg2 / xxxxxxxxxxxxxx)

But after trying to restart Homebridge, no accessory is created on the accessory dashboard.

Could you help me ? 
Other information available on demand

Thank you by advance

Best regards
