...PlatformIO is an open-source ecosystem for IoT development with the cross-platform build system, library manager and full support for Espressif ESP8266 development. It works on the popular host OS, Mac OS X, Windows, Linux 32/64, Linux ARM (like Raspberry Pi, BeagleBone, CubieBoard). Available in the PlatformIO registry. Pretty straightforward sketches, a simple light for example (TODO: adapt to V3). Cute HTTP API/Web UI/App to remotely send the configuration to the device and get information about it. ESP8266 framework for Homie, a lightweight MQTT convention for the IoT.
