In this tutorial I show you how you can use your Raspberry Pi to send a text message to your cellphone using Twilio. Sending text messages is useful if you want updates from your home automation system. In the context of the project I’m working on in the previous tutorial (and the next one), I will use this texting service to send myself a greeting message whenever I come home from work.
This is done using Twilio. I’m not affiliated with them, and there are other options out there. However it’s easy to get started with Twilio and the Raspberry Pi, so I thought I would show that. If you want to use another service or have your own GSM module and subscribe to provider, you will need to look elsewhere.
