Shelly 2.5 - several questions
Hi @alexryd,
Thanks for this great plugin!
Just finished my first Shelly installation and Homebridge setup.

1. After changing the config.json the plugin does not seem to use the new values until a Homebridge restart.

2. My shelly 2.5 is used as an in wall light switch. The plugin creates 2 accessories with 1 switch services. Both accessories report the same "serial number" to HomeKit.
It would be great to have 1 accessory with 2 switch services (at least a config option). Of course if you connect 2 different things to the Shelly 2.5 the 2 accessories are better.

It would be great if the serial number would be unique. I am the developer of the app "Controller for HomeKit" and the next version of the backup functionality will use accessory serial numbers to find accessories during restore. Because it's not unique, users have to assign them manually then.

3. The services has power state and consumption. Is it possible to notify changes in the consumption? This will result in more reliable UI refreshes in HomeKit apps.

Thanks a lot!
