Battery-powered ESP8266 beehive scale based on Homie
This is the low power battery version of :ref:`node-wifi-mqtt-homie`. The most recent version is available at `node-wifi-mqtt-homie-battery.ino`_. To run this sketch e.g. on the PCB Design from `ESP8266-BeeScale.fzz`_, you should remove and shortout the input polarity protection diode to avoid unnecessary voltage drop. Also you should remove any unnecessary power indicator LED to save a couple of mA. (e.g. on the ESP-07 the red power indicator LED). This will increase battery lifetime a lot.
