Low Battery Notification
With the recent version 2.27, battery information has been added for zigbee devices and DW2 sensor.

I have currently hard coded the threshold to 25%, ie, if a battery level drops below this, then HomeKit will display a low battery status.

So I wanted some opinions on this value of 25%:

* Do you think it's too high? Would a value of eg 10% be better?
* Would you prefer the option to define this % value yourself via the config?
