Further development of ESPilight / support for generic devices?

[MufflSeppl]

I recently stumbled across the brilliant pilight/ESPilight, but I'm surprised that there is no further development and no more support. The website www.pilight.org and the original forum are also no longer being maintained? Are there any resources where discussions are still taking place? I would be grateful for any tips...
For building sensors based on Arduino / ESP, it would be helpful if ESPilight send also supported generic devices. Would it be conceivable to incorporate support? Unfortunately, I'm not able to do that. But I could imagine that others would also be interested in this function.
