Room Monitoring Node

Python script to run a temperature/humidity sensor and write the results to a index.html, which is server by a http server on port 8000. Designed to be easily extendable with more sensors, user interfaces, etc.

Install requirements

Install system packages (most should already be installed)

sudo apt install -y git python3-dev i2c-tools python3-pil python3-pip python3-setuptools python3-rpi.gpio

Set up your virtual environment

python3 -m venv .venv

Activate your virtual environment

. .venv/bin/activate

Install requirements

pip install -r requirements.txt

Run the node

Run the node by running startNode.py

python3 startNode.py

Using C-c will kill the node and clean up the activated threads.

Access results

Results are currently visible by accessing http://<IP>:8000

Setup service (systemd)

Note that this may expose more files than you would like to. This is not secure(!!!) and will be changed in the near future.

Adjust monitorNode.service.example with the paths to your repository for ExecStart and ExecStop

i.e.

[Unit]
Description=Run Monitoring Node
After=multi-user.target

[Service]
Type=idle
ExecStart=/PATH/TO/YOUR/REPO/runAsService.sh
ExecStop=/PATH/TO/YOUR/REPO/stopService.sh

[Install]
WantedBy=multi-user.target

Then copy this file to /lib/systemd/system/monitorNode.service

sudo cp ./monitorNode.service.example /lib/systemd/system/monitorNode.service

To start the service, run

sudo systemctl start monitorNode.service

Enable the service

sudo systemctl enable monitorNode.service

Stop the service
