Hi All,
Today we're going to look at sending SMS messages from your IoT devices using Wia and Twilio.

P.S. If you want to see your devices on iOS and Android, pre-register here for our beta.

Create Your Wia Account

If you haven't already got one, click here to sign up.

Setup a Space

Once logged in, setup a new Space for your devices. I'm going to call mine My Devices. When your Space is ready, you should see a screen like the one below.

Add an Output Node

  • Drag over an SMS output node from the Twilio section in the panel on the left.
  • Select the node, then on the panel on the right, do the following:
  • Choose your From phone number
  • Enter your To phone number (NOTE: enter the country code and have no spaces i.e. +14568893405).
  • Enter your Body message. I'm going to set mine as Temperature is ${event.data}. This takes the temperature data from the Event. we are going to send. You can see more variables by clicking the Show variables panel link.
  • Click Update to save your changes.
