How to Control Your Raspberry Pi with Twilio SMS

This system allows users to remotely control their Raspberry Pi using SMS messages sent through the Twilio service. The process involves sending an SMS to a Twilio number, which triggers a webhook that calls a Python web application hosted on the Raspberry Pi. The web application receives the SMS content, evaluates it with a message handler, and performs an action on the Raspberry Pi GPIO pins based on the parsed command. A protocol is defined to understand the SMS format, where each action is associated with an object (e.g., "Light:switch:on"). The system can be extended by adding more controlled objects and implementing security measures such as filtering the SMS sender.
