temperatured

Application for measuring the temperature of a Raspberry Pi, and sending email alerts when temperature is over 70ºC.

Temperature is going to be measured using the command vcgencmd measure_temp, available by default in Raspberry Pi OS.

The application will be run as a systemd timer.

Is the application ready to use?

Yes, just compile it and set the following environment variables:

• TD_EMAIL_TO: Email address that is going to receive the alert.
• TD_EMAIL_FROM: Email address that is going to send the alert.
• TD_EMAIL_SUBJECT: Subject of the email alert.
• TD_EMAIL_TEXT: Body of the email alert.
• TD_SMTP_SERVER: Address of the SMTP server.
• TD_SMTP_DOMAIN: Fully qualified domain name corresponding to the email server.
• TD_SMTP_USER: SMTP server username.
• TD_SMTP_PASS: SMTP server password.

Or customize the code to meet your needs.

Cross-compilation from Fedora 32

For cross-compilation install:

cargo install cross

And execute:

cross rustc --target=armv7-unknown-linux-gnueabihf --release

Why the name temperatured?

The application has been named temperatured because it was originally created to be executed as a systemd timer.
