osem_notify 🔆🌡📡📈 ⚠ 📲

Cross platform command line application to run health checks against sensor stations registered on openSenseMap.org.

This tool lets you automatically check if senseBoxes are still runnning correctly, and when that's not the case, notifies you. Currently, email notifications are implemented, but other transports can be added easily. Implemented health checks are described below, and new ones can be added just as easily (given some knowledge of programming).

The tool has multiple modes of operation:

• osem_notify check boxes: run one-off checks on boxes
• osem_notify watch boxes: check boxes continuously.

Run osem_notify help or check the manual in the docs/ directory for more details.

get it

Download a build from the releases page. You can run the application by running ./osem_notify* in a terminal in your downloads directory.

On unix platforms you may need to make it executable, and can add it to your $PATH for convenience, so it is always callable via osem_notify:

chmod +x osem_notify*
sudo mv osem_notify* /usr/bin/osem_notify

configure it

The tool works out of the box for basic functionality, but must be configured to set up notifications. Configuration can be done via a YAML file located at ~/.osem_notify.yml or through environment variables. Run osem_notify help config for details and an example configuration.
