Hey, sorry it took me so long to answer. Honestly it has been a long time since I did this and I can’t quite remeber if the repo downloaded or not… Since then I switched to an rpi3 model b to which I added an respeaker 2 mic piHat. I am also running rhasspy in a docker container on this setup now, and everything works fine, except for the odd case that sometimes rhasspy doesnt understand my commands. But all in all I’m quite satisfied with this.
My next step will be trying to make it run on an rpi0, since the hat and zero have the same size and put it in an enclosure. Hopefully the enclosure wont interfere with the mics ability to pick up sound though.
Since it’s only a zero I also might just install it directly, without docker because I’m not sure the zero can handle running docker containers.
It’s really a shame, since I loved the DoA and Beam focusing with the respeaker core, and the grove ports where nice to have too… But it seems like Seeed dropped the respeaker core and are not improving on it anymore.

But if I have the time I might try to do the upgrade again, at the moment I have a lot of HomeAssistant automations to implement and configure 
Did you have any success since then?
