home_sensors

My personal project for collecting, processing, storing the sensor data I'm collecting in my home.

• celery/dockercompose/sqlalchemy

Celery Tasks

• Loading hubitat temp data into databases:
  • hubitat is configured to send data to my LAN server's /sensor flask route which calls receive_sensor_data()
  • load_sensor() celery task is called from the above route
• Pull / load public weather data:
  • Won't have anything to do with flask, just a timed (periodic) celery task

Docker Compose Notes

• must be in the directory where the docker-compose.yml file is for the following commands
• To rebuild the docker-compose containers: sudo docker-compose build
• To check if your docker compose is running, you run sudo docker-compose ps
• Spin up the docker-compose, sudo docker-compose up -d (-d puts it in the background). I also have a systemd service file that starts this up automatically in the event the server reboots.
• this is a great resource about configuring celery and rabbitmq

Hubitat notes

1. Using the Maker API app within hubitat, we can either push data to our LAN device at a dedicated IP, or I can poll endpoints continuously from my LAN device to my hubitat. I think it's a little cleaner to push the data instead of poll for it. That's the direction I'm taking for now.

Dev environment and deploying

It quickly became too much work to maintain my virtual box VM and keep that in-sync with the resources installed on my LAN server. So now I'm treating my LAN server as my development server.

When adding more functionality in the future:

1. make sure ./transfer_files_to_server.sh is pushing all the files my LAN server will need
2. update all of the .dockerfiles to make sure they all have the right files, dependencies, etc
3. run ./transfer_files_to_server.sh, ssh into the LAN server, navigate to the project directory, execute sudo docker-compose up -d

• omit the -d if you want to read the logs as data is passing through the system - useful for testing/debugging

Testing

To run tests (there's only a handful of tests for utils currently):

$ pytest -rA
