battery sender

Branch Description

This is the zero branch where development of the battery sender happens

Future Work

This program may read command line data for setting the loglevel before the configuration file is read.

Description

This daemon sends battery data onto the HAL network.

MQTT Publishing

Each battery reading is published onto the network under the run topic.

Each time the reporter/checkup_req is received, cached data is published under the checkup topic
