IO-PLUS ONLY: Adafruit IO's SMS Action requires your Adafruit IO account to have an active subscription to Adafruit IO PLUS. Adafruit IO PLUS ("IO+") is our PAID Adafruit IO plan. Visit for more info.

First head over to your Adafruit account page. Enter your phone number in the box and click continue and verify.

You should now receive a verification code at the mobile number you entered. Enter this code into the box labeled verification code. Press submit.

You should see a blue box that says Successfully validated phone number and your phone number in the box under mobile number.

If this is all correct you can continue to the next part of the guide.

From any page in Adafruit IO, click the link labeled Actions, then click New Action and select the Reactive Action option.

Fill out the options for this action. Make sure to choose the right feed and set the Limit Every option to a reasonable number so you aren't getting texts every 30 seconds.

We also changed the body so that it would tell us that the battery was fully charged instead of only the percentage.

When the battery is fully charged, you should receive a text message from Adafruit IO!
