Install Influx 1.7. on Raspian Stretch 

As I have the latest zwave version 3.0 running, which only is supported by Raspian Strecth, the default InfluxDB that gets installed is version 1.0.2 and not the latest (1.7.x as of 8/2019). In order to get the correct version on your Raspberry, do the following
1. Add „deb stretch stable“ to „/etc/apt/sources.list.d/influxdb.list“ 2. sudo apt-get update 3. sudo apt-get install influxdb 4. systemctl unmask influxdb.service 5. Enable Influx on boot: sudo systemctl enable influxdb 6. sudo systemctl start influxdb
