New Feature: SMS Inbound Messaging
Hello IO community! We’ve released a new Power-Up to Adafruit IO that should be fun to use and is included with existing IO+ subscriptions (see below for location details).
Inbound Messaging Service
The inbound messaging feature allows you to send a message to IO directly from a text on your phone.
For example, you can send a message to update the Lamp feed with the value of ‘off’ by sending
lamp, off
, and IO will respond with an “OK” if the operation was successful. Similarly, you can send a message oflamp
to receive the current value of the Lamp feed.We also support sending location data, such as
feed, value, latitude, longitued, elevation
.The rate limit for this feature is the same rate limit that is in place for the SMS Actions, and currently allows up to 25 messages per day.
You can set this up in your account via the Messaging Power-Up
Locations support to start
Similar to our SMS Actions update, we’re currently supporting USA and Canada.
The reasons for this are mostly around the high variability of the cost of SMS messaging. Our plan is to gradually add more locations.
As always, if you have any suggestions or bugs to report about this update, please let us know in the forums.

Adafruit IoT Monthly: Boxing Glove Tracker, Disconnecting Smart Appliances, and more!
IoT Projects
Buying, Programming, and Testing Capacitance Soil Moisture Sensors
A video of a maker’s exploration into capacitive-type soil moisture sensors. These sensors are frequently used by DIY soil monitoring projects (including some the Author of this newsletter has published). In the video, Modest Maker explains why “I don’t think you can just put these sensors in the ground and walk away”. - YouTube

Another Sensor Hub
An ESP32-based environmental sensor hub with a multi-use physical interface. - GitHub
VOC Monitor for a Print Shop
Clint Wolf built a monitor for their print shop because “print shops are concerned about indoor humidity as it can affect the transfer of, and drying characteristics, of ink and the media it is being applied to”. They cited another concern of working in a print shop is the air quality the staff is exposed to during the day. - Adafruit Blog
Room Temperature Circuit Sculpture
A sculpture made from brass rods, an Arduino, a temperature sensor, and a block of walnut. Editor’s note: While this project is not connected to the internet, it’s a really beautiful example of circuit art and I wanted to include it. - HackADay.io

Connecting a complicated boiler system to Home Assistant
Gray Malk’s home has an unconventional heating system. There’s a heating zone for the upstairs (using radiators) and then another for downstairs (using underfloor heating). Due to this, they found none of the off-the-shelf solutions would work, except for a £300 option. In the blog, they detail how they rolled their own custom solution. -Gray Malk

Adafruit IoT Monthly: 2022 in Recap!
Editor’s Note
Hello readers! I hope you are warm and cozy, and reading this issue in the new year. This is the last newsletter I’ll be writing in 2022. This issue will read a little differently. Below, I’ll be listing my favorite things posted in the Adafruit IoT Monthly during 2022.
If you’re one of the 1,000+ new subscribers in 2022 - welcome! My name is Brent and I’m an engineer at Adafruit Industries who works on all sorts of things, including this newsletter. The IoT Monthly was previously known as the Adafruit.io newsletter and only contained news and projects about our Adafruit.io IoT Platform. In 2019, we expanded this newsletter to the broader topic of the Internet of Things. Unlike Adafruit’s other newsletters which are sent on a frequent basis, this newsletter is distributed only once a month, giving me time to gather information from across the ‘net and giving you time to breathe.
This past year, I’ve been working with the team on Adafruit’s IoT offerings. Specifically, I’ve been working on enhancing and improving Adafruit.io and WipperSnapper, our (beta) no-code IoT firmware. In a year, we’ve seen thousands of people try this platform out for the first time. We’ve added support for more I2C sensors, OneWire sensors, PWM outputs (such as buzzers, and switches), and even servos.
The WipperSnapper firmware is now more stable and we’ve redesigned the onboarding process to help folks create their connected electronics project even faster. We’ve also added platform support for the ESP32-C3, ESP8266, and Raspberry Pi RP2040. And there’s still more to come in 2023, including power-saving sleep modes, displays, new transport types, offline logging, more projects, increased board support, and increased component support.
Thank (over 5,000+ of) you for subscribing to this newsletter. Next month’s issue will return to regular programming.
Cheers,
p.s.: If you have any feedback about this newsletter, or want to submit something you’re working on, send an email to iotnews@adafruit.com.
