A NodeJS server and Python scripts to set up a SMS-capable WiFi relay.

A combination of the old RPiCafeLogging (formerly RPiCafe) repo and the ATF-Sonoff-Server

Designed on a Raspberry Pi 3 Model B

If you haven't already, a Google account should be created specically for your Raspberry Pi. Then set up Google Voice for the account at voice.google.com.

Afterwards, visit https://accounts.google.com/DisplayUnlockCaptcha and allow access to third-party applications without the need for Captcha verification.

• THE FILES WILL HOLD YOUR ROUTER'S PASSWORD IN PLAIN TEXT.
• THE SCRIPTS WILL HOLD YOUR GOOGLE PASSWORD IN PLAIN TEXT. This is why a separate account is suggested.
• SOME OF THE NODE MODULES MAY NOT BE AS SAFE AS THEY SHOULD BE. PLEASE BE CAREFUL.

1. Clone the repository onto a Raspberry Pi.

2. Once the repository is cloned, type "./update.sh" into a terminal to run the update and install scripts.

3. Start the NodeJS server using the sonoff.server.js file.

4. Connect the Sonoff device to the server -- instructions at https://github.com/mdopp/simple-sonoff-server.

I have written about my experience setting up the server and more on my website. You can read about it here: https://austin.fritzemeier.info/projects.html#RPiSMS

The install.sh does ask if some of these are installed (marked with *), others may need to be manually installed.

This project was inspired by sleepless nights, impending due dates and limited financial resources.

The Initial Plan: A Raspberry Pi would control a relay connected to a coffee machine. The Pi would receive SMS messages containing key words determining whether to toggle the relay immediately or schedule it to execute later.

Cron runs a python script every second to check the Google Voice SMS inbox for keywords within text messages from the specified sender. Cron will also log into coffeecron.log in case any errors arise.

Currently, the keywords are "coffee", "cancel" and "schedule coffee TIME" where TIME is when the script should run, specified in military time (0000 - 2359).

If the correct keywords are found, the script will execute the command, log the event in a text file and send an SMS message back to the sender stating that the operation has been completed.

Similarly, if an incorrect keyword is attempted, the script will log said phrase in the text file and send a message to the user's specified number.

These scripts may be adjusted to the user's liking, such as changing the keywords or the specified scripts to be run. It may be possible to run shell commands on the Pi directly from SMS with simple modifications.
