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
Having fun with hyperlocal data
Alex S. writes about using the Pimoroni wireless sensors to send all kinds of hyperlocal data to the internet. – lagomor.ph

6 Smart Home Finds from CES 2023 (that aren’t about the Matter standard)
This year’s CES event came and went with a lot of talk about the new Matter standard. The Verge recaps a few products on the show floor that weren’t focused on Matter. – TheVerge
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
Here at Adafruit, we sell all of these amazing components, but we couldn’t find a good way to interact with them over the Internet. So, we decided to create our own IoT platform, and that’s Adafruit IO. It’s built from the ground up to be easy to use and platform agnostic (connect any development board or device!).
Adafruit publishes a wide range of writing and video content, including interviews and reporting on the maker market and the wider technology world. Our standards page is intended as a guide to best practices that Adafruit uses, as well as an outline of the ethical standards Adafruit aspires to. While Adafruit is not an independent journalistic institution, Adafruit strives to be a fair, informative, and positive voice within the community – check it out here: adafruit.com/editorialstandards
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
