I’ve always been fascinated by the idea of integrating visual notifications into my smart home setup. Imagine being able to see when your washing machine finishes, or when the oven is preheated, without constantly checking your phone. After experimenting with various solutions, I stumbled upon WLED and Node-RED, which together offered a seamless and customizable way to achieve this.
The Challenge
I initially looked into traditional smart bulbs like Hue and Tradfri, but they came with their own set of complications. Customizing effects required handling the lights’ states manually, which could interfere with existing automations. Plus, lights without built-in effects made it even more complex, requiring workarounds that could bog down the network.
The Solution
Enter WLED. Its UDP Realtime control protocol allows for temporary state overrides, making it perfect for notifications. I developed a Node-RED node that simplifies the process, enabling anyone to send visual notifications with just a single command. The setup is straightforward: you just need to input the WLED device’s hostname or IP, and the rest is handled automatically.
Customization and Flexibility
Currently, the node supports a “blink” effect that can be highly customized. Whether you want a quick flash or a prolonged glow, the settings are entirely up to you. This flexibility means the notifications can be tailored to suit different scenarios, from subtle alerts to more attention-grabbing effects.
Real-World Application
I’ve been using this setup for a while now, and it’s been a game-changer. For instance, when my washing machine finishes, the lights in my living room briefly blink, letting me know without me even needing to look at my phone. It’s these small conveniences that make home automation truly shine.
Contributions and Feedback
I’m always looking to improve this solution, and I’d love to hear from anyone who finds it useful or has suggestions for new features. Contributions are welcome, whether it’s through code improvements or testing new ideas.
