In my last donation to the project, I pledged another 300 EUR once Homematic-AES support over the busbare devices is working. I thought maybe others would like to contribute pledges, too?
Maybe the developers would like to set up a Kickstarter project or some kind of bounty scheme for this?
Maybe this could be opened up for other hackers, too? The developers could promise a certain percentage share of the bounty to anyone who solve parts of the problem?
