Instructions for Raspberry Pi Zero W

Initial setup

sudo apt update && sudo apt upgrade
sudo apt install python3-pip
mkdir -p ~/.local/bin

Install Docker

curl -fsSL https://get.docker.com -o get-docker.sh
chmod +x  get-docker.sh
sudo ./get-docker.sh
sudo usermod -aG docker pi

Logout, then log back in.

Test using an ARM32 v6 Alpine image

docker run -it --rm arm32v6/alpine:latest /bin/sh

/ # cat /etc/os-release

Install docker compose

pip3 install docker-compose
docker-compose --version

Get InfluxDB and Chronograf

A docker-compose.yml exists for InfluxDB and Chronograf with ARM32V6 images.

Run it

    cd measurements
    docker-compose up -d

Wait up to 5 minutes for Influx and Chronograf to come up!

Backup db:

docker exec -it influxdb influxd backup -portable /backups/

Restore db:

docker exec -it influxdb influxd restore -portable /backups/

Then browse to http://raspberrypi/ for the Chronograf interface

Set up dependencies

Some missing dependencies first.

# Enviro lib
cd enviroplus
sudo ./install.sh
cd ..

# Influx lib
pip3 install influxdb

Run the main sensors script

Via crontab:

@reboot sleep 60 && cd /home/pi/enviro-influx-chronograf/measurements && python3 everything.py &

Manually:

cd measurements
python3 everything.py

Run the pihole stats collection script

Via crontab:

30 * * * * cd /home/pi/enviro-influx-chronograf/measurements && python3 piholestats.py > piholestats.log 2>&1

Manually:

cd measurements
python3 piholestats.py

Run the backup scripts

Via crontab:

00 * * * * cd /home/pi/enviro-influx-chronograf/measurements && bash backup.sh > backup.log 2>&1

Manually:

cd measurements
./backup.sh
