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

Dracula Sucks Indoor Light to Power IoT Devices

Given the hungry power needs of the rapidly expanding realm of the Internet of Things, clever solutions are needed to generate and conserve energy consumed by these devices. One such solution is Dracula. No, not the blood-sucking Transylvanian count, the ambient indoor light-sucking technology.. - Adafruit Blog

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,

Brent

TurtleSense Disguises a Sensor Package as a Loggerhead Egg

Researchers hid an accelerometer in a fake turtle egg [a ping pong ball] to send data via SMS. With this data, people will be able to understand more about the nesting/hatching process and deploy effective protection for the turtles. - Adafruit Learning System

No-Code IoT Pool Monitor

You can build your own IoT Pool Monitor (without code!) using Adafruit IO and WipperSnapper. This can help you keep track of water temperatures by logging and plotting data to a dashboard! All of the electronics are housed in a clear sealed enclosure that is also water resistant. - Adafruit Learning System

Pico W HTTP Server with CircuitPython

Set up an HTTP (web) server with a Pico W running CircuitPython. HTTP servers are handy for creating custom web interfaces to monitor and control IoT projects. - Adafruit Learning System

BLE Soil Sensor

b-parasite is an open-source Bluetooth Low Energy (BLE) soil moisture and ambient temperature/humidity/light sensor. - GitHub

Home Buttons

An open-source device for locally controlling your smart home. While this is a purchasable project, the technical overview on the build log is informative for anyone looking to build a smart panel. - Hackaday.io

Circadian Lighting a Home

Light messes with Tyler’s head, so they built a way to auto-adjust the lights in their home according to circadian lighting. This is a self-hosted solution, replacing something which would be commercially offered by a vendor such as Philips. - tylercipriani.com

Turbidity Sensor

An open-source, low-cost, in-situ turbidity sensor for river network monitoring. Results and data from this sensor were published in Scientific Reports. - GitHub

Starting today, November 15th, 2022, all new Power-Ups in IO for the weather service will be using Apple’s WeatherKit weather service.

Dark Sky has been deprecated and will be shut down on March 31st, 2023. All existing weather integrations will continue to work until that time.

We recommend that prior to that deadline you migrate your existing weather integrations to the new WeatherKit weather service.

The steps to create the integration are the same, and we will automatically default to the new service for you.

If you need help migrating your client code, Apple has a Transitioning from Dark Sky section that provides field mapping data from Dark Sky to WeatherKit.

As always, if you have any suggestions or bugs to report about this update, please let us know in the forums.
