Parser mode

Parse MQTT 'message' data

Note, this function was intoduced in MQTTSubscribe version 3.0.

This reads data from a file and attempts to parse it into WeeWX format.

This functionality is useful for people that do not have acces to the live MQTT feed, such as MQTTSubscribe developers.

Environment setup

If running as a driver,

RUN_MODE=driver

If running as a service,

RUN_MODE=service

For pip and git installs - activate the environment

source ~/weewx-venv/bin/activate

WEEWX_REPO=~/weewx
WEEWX_ROOT=~/weewx-data
