Adding battery level widget by device

[BabaIsYou]

Hi Smanar,

What do you thing about reusing some parts of this Domoticz plugin Battery level for Z-Wave to have the same option for Zigbee devices ?

As you already parse the whole zigbee devices could it be "easy" to create a battery level widget per Deconz device, (and not one per sensor of course if they share the same battery attribute) ?

Could be a nice integrated and optionnal (by configuration options) feature that could help to get notification per custom battery level and not for the same treshold for whole Domoticz.
