Low Battery information at start in Eve
Hi dude, when the homebridge instance with this plugin restart, for example, when you add a new hygrothermograph to the config.json, in the Eve App you can see a couple of minutes the "Low Battery" icon associated to the accesossrie. In the Home App don´t show the Battery Information at all, if you wait 2 minutes (or something like that) the info appears again.
Maybe you can cache Battery information using Homebridge persistence capabilities, the first Battery info that the accessory shows is the cached one, meanwhile the plugin do whatever do ;) for take the correct value (battery levels don't change quickly, i think that it's ok show a cached info when the plugin brings to life after a restart).

Regards
