Battery-powered ESP8266 beehive scale based on Homie#


Please continue reading this document on our documentation space, all inline links will be working there.


This is the low-power version of ESP8266 beehive scale based on Homie, in order to run the device on batteries.

The most recent version is available at node-homie-lowpower.ino. To run this sketch e.g. on the PCB Design from ESP8266-BeeScale.fzz, you should remove and short-out 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. For example, on the ESP-07 the red power indicator LED. This will increase battery life-time a lot.
