Adafruit WiFi Action Key for Home Assistant / ESPHome

Published: March 2, 2023 / Last Modified: March 2, 2023 / Leave a Comment / Adafruit, Gadgets, Hardware, Home Assistant, RISC-V

I’ve covered making a wireless Adafruit IoT button that can run any action within Home Assistant when you press the button using automations. These are great because they also have a RGB LED built in that you can use to show the status of something being controlled by the button.

For example if you used it to control your garage door you could make the button red when your garage door is open and green when it’s shut. This way just by looking at the button you know what the state of the garage door is.

Today I am going to cover something really similar: a single WiFi action key using gear from Adafruit as well as a RISC-V ESP32-C3 module. These also have individual RGB LEDs for each key just like the IoT button giving them the same advantages. Let’s begin!

QT Py + Grove SEN54 - Deployment (Closeup)

I’ve previously covered creating a Home Assistant air quality monitor system using a XAIO ESP32-C3 module and ESPHome / Home Assistant to create a 7-in-1 air quality monitor sensor. My previous article though did require a little bit of soldering to get it going.

Today I’m going to show you my latest sensor build which has completely eliminated the soldering. It’s plug and play using ESPHome and Home Assistant. I did this using the Adafruit QT Py module which has a built-in connector for connecting to a I2C (Stemma QT) device like the Grove SEN54 environmental sensor. In addition to eliminating any soldering this also saved me money by not having to buy an expansion board.

Today I’ll show you the updated build for my air quality sensor setup I’ll be using throughout my home. Let’s get started!

Minoston Z-wave Smart Plugs w/ Home Assistant Review

Published: February 28, 2023 / Last Modified: March 15, 2023 / 4 Comments / Gadgets, Hardware, Home Assistant, Reviews

I’ve been covering integrating my entire home into Home Assistant here on the site. I want to have the capability to monitor everything going on in my home and control it with an open-source system such as Home Assistant.

Although I have a strong WiFi network in my home there are some areas where using a wireless technology that is more energy efficient (such as Z-wave and Zigbee) makes a lot more sense. These especially include devices that need to run on a battery or are in awkward areas with poor WiFi coverage.

I decided to try the Minoston Z-wave mini plug to see how it integrated with my Home Assistant setup as it was very commonly recommended online. In this review we’ll take a look at this device and see if it’s worth using. Let’s begin!

Zooz 700 series door/window sensor - Review

I’ve been upgrading all of the devices in my home to work with Home Assistant and eliminate subscriptions to proprietary services. One of the last remaining subscription services I have in my home is the Ring door and window sensors. The Ring ones have honestly been fine but the subscription is not free. Since I know these sensors will be installed in my home for 10+ years it will save me money to switch to something else that has no subscription.

That is why I was excited to see that Zooz has released a new series of Z-Wave door and window sensors that are completely self-managed by either a Z-Wave hub or Home Assistant running as a Z-Wave hub. The advantage of Z-Wave and Zigbee devices is they use much less power than WiFi so it’s a much better suited technology for devices that run on battery power (such as wireless door and window sensors).

In this review I’ll cover the Zooz 700 Z-Wave door and window sensors and cover the upsides and downsides of the system. Let’s get started!

Genie Garage Door Opener Aladdin Smart Home Upgrade

Published: February 24, 2023 / Last Modified: March 15, 2023 / 5 Comments / Gadgets, Hardware, Home Assistant

I’ve been investigating ways to make my garage doors on my home “smart”. My overall goal is to implement them into Home Assistant. I’ve been investigating various options to do this including do-it-yourself with ESP modules (which I’ve used for a lot of other parts of my home automation).

My home is only about 3 years old and came preinstalled with a “dumb” Genie garage door system that does not have smart capabilities. I decided to investigate the official upgrade option offered by the company via their Aladdin smart home upgrade kit as it only cost about $60.

In this guide I’ll cover installing the upgrade kit for Genie garage doors and how well it performed. I’ll also cover implementing it within Home Assistant. Let’s get started!

Adafruit 7 Segment Display + Rotary Encoder + QT Py

I’ve been doing a lot of coverage of ESP32-related chips lately on the site. One thing that is a bit painful with them though is that they usually require a lot of soldering. That’s why I find the Adafruit QT Py series of ESP32 chips so exciting. They eliminate the soldering!

Unfortunately once I got all of my parts and tried to get started I ran into several issues that are not covered at all (or very poorly covered) by the official documentation and guides available. None of the things I’m going to cover were particularly difficult once you know what they are and how to address them. I did however lose days or closer to a week of time messing with this as I had to figure it all out from piecing together scraps here and there from forum posts.

In this guide I’ll show you how to get Arduino working with the Adafruit QT Py boards using Stemma and how to avoid all the pitfalls that I lost a lot of time on getting started. Let’s begin!

Home Assistant Tiny WiFi Button Guide ft. Adafruit QT Py

Published: February 16, 2023 / Last Modified: March 5, 2023 / 2 Comments / Adafruit, Gadgets, Hardware, Home Assistant, RISC-V

I’ve been documenting my journey building out my smart home powered by Home Assistant here on the site. Home Assistant is an open-source system designed to let you easily manage and automate everything in your home.

That’s when I saw that Adafruit’s QT Py series of boards had a tiny IoT button available for it I immediately thought of Home Assistant. The button could be used to automate anything in your home you’d like. You could program it to turn off / turn on lights, open/close the garage door for you, turn on and off certain appliances or anything else you could imagine being able to do with a wireless-enabled button.

In this guide I’ll show you how to build and program a wireless button with Home Assistant. Let’s get started!

Home Assistant Grove All-in-one Environmental Sensor Guide

Published: February 15, 2023 / Last Modified: March 15, 2023 / 8 Comments / Gadgets, Hardware, Home Assistant, Seeed Studios

I’ve been building out various sensor arrays for use with Home Assistant in my home using ESP32 modules and ESPHome and it has been working really well. One challenge though is that you have a limited number of connections (even when using expansion boards). This can be dealt with a few different ways but buying a whole bunch of individual sensor boards one at a time and connecting them can get messy to say the least.

Fortunately Seeed Studios has a unit powered by Sensirion that has 7 environmental sensors all in one: the SEN54! This includes measurements for particles of PM1.0/2.5/4/10, temperature and humidity and VOC (volatile organic compounds). All in one unit with a single connection.

In this guide I’ll show what adding a sensor like this to Home Assistant looks like using ESPHome and a ESP32-C3 module. Let’s get started!

Adafruit Re-programmable USB-C PD Cable Review

I have been ordering a lot of gear from Adafruit lately to help build my Home Assistant sensor array for my home (as well as other projects I have going here on the site). I was very confused today when something showed up I didn’t recognize (and wasn’t even aware really existed).

It turns out to be a cable that you plug into a USB-C power adapter that supports PD (power delivery) and output a voltage you program in via a DC barrel jack. In other words this cable lets you turn a USB-PD capable power adapter into a programmable DC jack adapter that could theoretically work with almost anything!

This is a $19.50 cable I’m certain that I didn’t buy that I will return to Adafruit if they would like. Not before we review it first though. Let’s get started!

Pine64 SOQuartz Blade Review

Published: February 9, 2023 / Last Modified: April 22, 2026 / 41 Comments / Benchmarking, Hardware, Reviews

I’ve previously reviewed the Pine64 SOQuartz here on the site and found that if you used Armbian it was a feasible alternative to the CM4. The compatibility with other IO boards varies wildly though. We’ve definitely seen mixed experiences using the CM4 Blade when using the SOQuartz for example.

I was curious if I got a hold of one of the official Pine64 SOQuartz Blade boards if the experience would be better. Today we will review the Pine64 SOQuartz Blade IO board and see how well things are working at time of writing.
