Knowing where to start when adding a device to your home automation is always a tough thing. Most likely, you are already working on the device end of things (whatever you’re trying to automate) so it would be nice if the user end is already figured out. This is one such case. [Aditya Tannu] is using Siri to control ESP8266 connected devices by leveraging the functionality of Apple’s HomeKit protocols.
HomeKit is a framework from Apple that uses Siri as the voice activation on the user end of the system. Just like Amazon’s voice-control automation, this is ripe for exploration. [Aditya] is building upon the HAP-NodeJS package which implements a HomeKit Accessory Server using anything that will run Node.
Once the server is up and running (in this case, on a raspberry Pi) each connected device simply needs to communicate via MQTT. The Arduino IDE is used to program an ESP8266, and there are plenty of MQTT sketches out there that may be used for this purpose. The most recent example build from [Aditya] is a retrofit for a fiber optic lamp. He added an ESP8266 board and replaced the stock LEDs with WS2812 modules. The current version, demonstrated below, has on/off and color control for the device.
