Noodle Project

The Noodle Project is a pet snake environment controller. The project does things like act as a thermostat for heating elements and record environment humidity and temperature.

The latest (seemingly) stable build is in the dev branch.

Just a note: CMake is a real drain on my life.

The device currently publishes data frequently. This is desirable for something like real time reporting. Two minutes seems like an appropriate interval for this project.

TODO

Monitor OneWire for changes to connected sensors
- use inotify on a new thread to check for changes in the mount dir https://www.thegeekstuff.com/2010/04/inotify-c-program-example/
Shut off heat sources if the temperature reading fails.
Shut off heat sources if the program is not running. Supply power to relay from device? Will the relay auto-trip?
Status report of software version, device id, connected widgets

Build

For testing, use run.sh.

Local testing

#!/usr/bin/env bash

mkdir -p build
cd build
cmake -DCMAKE_BUILD_TYPE=debug -DDAEMON=OFF ../
make
./noodle

Daemon testing

Local testing should be fine for most instances. Daemon testing just makes sure the installation goes well and the services is configured properly.

#!/usr/bin/env bash

mkdir -p build
cd build
cmake -DCMAKE_BUILD_TYPE=debug -DDAEMON=ON ../
make
sudo make install
sudo systemctl start noodle

Release

./build.sh
