### What issue do you have? Please be as thorough and explicit as possible.
The plugin won't update device list when fetching the home setup. My old deleted device (Kitchen light) is still "found" and any new ones are not. I can see the correct devices in the ewe app but not in homebridge.


### Details of your setup.
* Do you use (1) Homebridge UI-X (2) Homebridge CLI or (3) HOOBS? 
homebridge-config-ui-x v4.50.2


* Which version of Homebridge/HOOBS do you have?
Homebridge v1.5.1 (HAP v0.10.4)


* Which platform do you run Homebridge/HOOBS on (e.g. Raspberry Pi/Windows/HOOBS Box)? Please also mention your version of Node.js/NPM if known.
RPi, node v16.16.0



* Which version of this plugin (homebridge-ewelink) do you have? Has the issue started since upgrading from a previous version?
homebridge-ewelink v10.3.0


* Which eWeLink devices do you have that are causing issues? Please include product models if applicable.
