The server sees this and says “looks like they want to talk to the API!”

IP address of the WLED install that we are working with.ĪPI endpoint. As explained earlier, HTTP works by a client sending a request to a server which then returns a response. By default without any options, curl will send an HTTP GET request. Luckily we only need to send a basic HTTP GET request. There are many different options you can use with curl. Let’s break down the following command so you understand what you are doing. We will be using a Linux utility named curl to make our HTTP requests to the WLED API. That’s what we will be working with today. GETĪs of this post, the WLED HTTP request API only uses GET requests. There are many different types of HTTP requests. This means we can use our Raspberry Pi to send commands to WLED and If you’ve never worked with an API or the command line before, the documentation can be daunting.ĪPIs are awesome because they allow you to manipulate applications remotely (usually using HTTP) or locally. Meaning it provides an interface that allows us to send or receive information to an application. The server looks at the request for and says, “Oh hi, you want the homepage for ? Sure thing, here you go!”, and then it sends back the webpage at the URL you requested.ĪPI stands for Application Programming Interface. When you type a URL into your browser it makes an HTTP GET request to the server where that website lives. HTTP is the client/server protocol that runs a lot of the internet. To talk to the ESP8266 we will be using HTTP (HyperText Transfer Protocol). Output 5V and up to 2.4 Amps to the ESP8266. I do a lot of projects so the 3 pack has been the best value for me. You just need to make sure it is capable of carrying power as well as data. You probably have 38 of these in your junk drawer. Used to connect the ESP8266 to the LED strips. No one does just 1 WLED project and they are really inexpensive.
Honestly, you might as well get the 4 pack. I have been running these cards in all of my Raspberry Pis for a while without issue. It’s a pretty good deal for the price if you don’t have the parts already. This kit comes with the board, power supply and heat sinks. I used a Raspberry Pi 4 4GB to make this tutorial but you can absolutely use another version of the Pi if you have one laying around. Here are all the parts I used to make this work.

If not, check out how to get started with WLED and then come back here. You should also have a working installation of WLED already. I wrote this tutorial using a Raspberry Pi running the latest version of Raspbian but it should work on pretty much any host running Linux. This tutorial aims to help those people automate their WLED setups. A lot of people are already using a Raspberry Pi at home for one thing or another. Not everyone has a smarthome running SmartThings or HomeAssistant. I use SmartThings and webCoRE to automate my WLED installs but I totally understand why people are asking for this. So I decided to make a post covering both requests. How can I control WLED with a Raspberry Pi? These are the 2 most common requests/questions I get… I have had many people contact me via Twitter or email me about these posts.
Since then, I’ve been making a bunch of WLED tutorials. I have 10+ WLED installs in my house as I write this. I started using WLED last year and quickly switched all of my other LEDs over.
