WiFi RGB LED Strip Music Visualization

WiFi RGB LED Strip Music Visualization

Continuing off of my post from last week creating a WiFi Connected RGB LED Strip, I’m adding a new effect: music visualization. The goals of the project are:

  • LED strip syncs to the music playing
  • The audio comes in from a headphone jack
  • LED strip should still be able to support a solid color and other visualizations
  • Controllable over WiFi and using Home Assistant
  • The LEDs add a subtle visualization to the music, don’t want my living room becoming a rave
  • Everything should be hidden well for a high spouse approval factor

4 Essential Tips for Improving Your DIY Home Automation Projects

4 Essential Tips for Improving Your DIY Home Automation Project

Home Automation projects are rarely “complete”. They evolve over time. A few weeks ago I posted an article about creating a DIY garage door opener using MicroPython. Since then, I received lots of awesome feedback from the community and improved the design. I’ve summarized the feedback into 4 essential tips for improving your DIY Home Automation project.

  • Use PlatformIO for Build Environment
  • Add temperature and humidity sensors
  • Update your firmware over WiFi using over the air updates
  • Add a heartbeat

Check out the original article on how to create DIY Smart Garage Door Opener if you haven’t already, to get a starting point for this project. These could also be applied to my DIY Bed Presence Detection solution or any other DIY home automation project you’re working on.

DIY Bed Presence Detection in Home Assistant

Ever want to create an automation around someone sitting on a chair or laying in bed? Using an ESP8266, load cells, an MQTT broker and Home Assistant you can create a DIY weight sensor attached to your bed to form a smart bed! This that will allow you to detect these events and trigger automations.

While you could use this to accurately measure the weight of something, I’m focused on detecting presence on a piece of furniture. You can use this data to create automations based on where people are currently located in your home.

Some hardware you’ll need:

Start Docker Compose using systemd on Debian

How do you start up your multi-container application? Lots of the time these multi-container setups have dependencies between them and you need to start them in a specific order? How can you get this done automatically on bootup? Today I’m going over how to use Docker Compose and systemd to automatically launch all your containers in the correct order on bootup leveraging systemd on a Debian host.

So if you’ve got an MQTT broker (or another service) that must start up before your Home Assistant service and you’re already using Docker Compose this is an article for you! This method works great on a Raspberry Pi but should also work on anything using systemd as the initilization system.

Home Assistant Notification Showdown

Notifications are an important part of a Home Automation platform. Users typically want to get alerted when things happen and there are various degrees of importance for notifications. Right now in Home Assistant 0.76.2 there are 60 different notification platforms! In this post I’m going to review several different notification platforms supported in Home Assistant. You probably don’t want an email when your garage door doesn’t close but an email might make sense for a weekly electricity usage report, I’ll go over some use cases for each type of notification.

We’re an Android household so this review is coming from that perspective, if you’re using iOS there is a Home Assistant iOS App that supports notifications that I’ve heard good things about. You may also find some of the other notification platforms discussed in this post to be useful to supplement.
