I wanted to create a new component where you can toggle the Milight bulbs without having to use a wifi hub by using a RF transmitter at my Raspberry. Recently I found a really nice github project written in C++ which I would slightly adapt for the use in Home Assistant Components (https://github.com/bakkerr/openmilight_pi). But I don’t have the time to rewrite the whole thing in Python (and the by this project required sub-projects). Is it possible to use C++ in the requirements somehow. And if yes, would it be possible to use this component in hassio as well?
Although you said you don’t want to use a wifi hub, I’m unsure whether you explored alternative DYI solutions. Also, he library pointed is old and (most probably) doesn’t have support for newer v6 protocol.
See the following project (it uses NRF24L01 and NodeMCU connected to HA over MQTT which is a big step forward from ibox; it is still wifi but it is a very powerful device):
