Openwrt oriented shell script for Xiami Miflora plant sensor.
Pure shell script, no pythons required.
Meant to run as a daily cronjob,
fetches (historic) data from Xiaomi Miflora sensor.
uses gatttool for talke BLE to the sensor and rrdtool(1) to store readings and create graphs
still needs clean-up, but usable nonetheless ;-)
Mainly checking momentary values instead of historic values: no bulk read is possibly anyway, so no (power) benefit in reading the history.
The script (gatttool) assumes the BT-dongle to be 'up'.
do /usr/bin/hciconfig hci0 up before calling miflora-rrd
(or just add that line to /etc/rc.local)
