 export Pacer data to InfluxDB
 
-based on https://github.com/korjavin/sqlite2influxdb
-
+  * original code from https://github.com/korjavin/sqlite2influxdb and https://github.com/influxdata/influxdb-python
+  * sqlite database is /data/data/cc.pacer.androidapp/databases/MDData.db on an Android device, may need root privileges to get it
+  * collects steps, distance, active time and calories
+  * for now InfluxDB database needs to be created first
+  * incremental feed: just insert missing points
+  * grafana dashboard export in json format is included, adjust datasource name
