From version 0.7.1, WLED supports the free IoT cloud Blynk! See [this](https://github.com/Aircoookie/WLED/wiki/Blynk/) for details! It has a nice app for you to control the lights from anywhere!
If you have set up your Alexa device to control WLED, you can just use the Alexa App or another Echo device linked to your account to control your lights (on/off and brightness only)
Setting up an [OTA lock password](https://github.com/Aircoookie/WLED/wiki/Security) is a must to prevent attackers from acquiring your WiFi credentials!
Additionally, this opens up many new possibilities for automation! You can use a service like [IFTTT](https://ifttt.com/) Webhooks to send automated WLED API calls that can do anything from turning on the lights at a set time to changing their color if you get a new email!
If you have a Philips hue setup and sync WLED to it, you can control your WLED lights in any way it's possible to control your hue lights (hue App, Alexa (including colors), any other service that uses Philips hue API)
