Dependencies

This repository also provides a Makefile, but it does not work currently. So the only option to compile and upload is via the Arduino IDE:

Install ESP8266 Arduino Board Support from Boards Manager
Select you board and upload port
Compile and upload. (push the reset button just before the upload starts to wake the chip from deep sleep.)

Settings

All configuration is currently done with preprocessor constants in the code itself.

NODENAME: User friendly name of the node (used for the influxDB measurements)
BOARD: Board type (see line 17 ff.) for the right battery settings
DB_HOSTNAME: Host/ domain name of your influxDB (port is fixed to 8086)
DB_PASSWD: HTTP BasicAuth string used to sign in

Battery Lifespan

ESP12: About 6 months
