Replace the SENDER and RECIPIENT variables with strings of desired email accounts. They can be the same email for each variable.
The SENDER must be a gmail account with the current script. The Gmail class may be modified in the future to work with different providers.
This is a simple python2 script designed to detect when the Sustainable Atmospheres Research Lab's PurpleAir sensors stop uploading to their respective API.
The script scans PurpleAir's API every 15 minutes. If a sensor goes offline for more than 1 hour, an email is sent to the user. The offending sensor ID is also appended to a list of offline_sensors to prevent multiple emails being sent per day. This list is cleared every 24 hours, to remind the user if a sensor has been offline over consecutive days.
The email class was developed with gmail accounts in mind. It may not work with other SENDER addresses.
Getpass allows the user to privately enter the email SENDER password via commandline to avoid the security issues of a hardcoded password.
