RGBW wifi box

Got recently an RGBW wifi box based of esp8266
Is anyone aware of an alternative RGBW (underline the W) firmware which can be controlled from HA via MQTT or other means?

Thanks for the links. Both working great. But wonder if there are also projects supporting HA effects? Christmas is coming after all )
