Collect data from various sensors (see gan) and use rrdtool to generate graphs.

My own home monitoring setup involves one instance of stasi running directly on a Raspberri Pi, which syncs data from multiple Raspberry Pi Zero devices that collect data using gan.

The ideal way is to start from a gan instance, as built by gan-gen.

1. Clone the stasi repo
2. Create the config file
3. sudo apt install python3-rrdtool nginx
4. Run the commands manually for the first time - both to make sure it works, and because it will take a long time to sync if you have a lot of data
   • mkdir /home/gan/stasi-data/
   • /home/gan/stasi/scripts/sync.sh
   • python3 /home/gan/stasi/scripts/rrd_import.py /home/gan/stasi-data/
   • /home/gan/stasi/scripts/graph.sh
5. Set up a cron job to do this periodically
   • sudo touch /var/log/cron.log && chmod a+w /var/log/cron.log
   • crontab -e
   • * * * * * /home/gan/stasi/scripts/sync.sh >> /var/log/cron.log 2>&1 && python3 /home/gan/stasi/scripts/rrd_import.py /home/gan/stasi-data/ >> /var/log/cron.log 2>&1 && /home/gan/stasi/scripts/graph.sh >> /var/log/cron.log 2>&1 && echo DONE at date >> /var/log/cron.log

I use this system for my own home monitoring setup and it works fine, but it might not work for everyone nor is it easy enough to install for everyone.
