OpenWRT is a good community. I made a garden sprinkler controller using OpenWRT and an Arduino Yun a few years back. Seems like OpenWRT has since added support for a few mesh standards. Another mesh community is Thread, which seems to have Zig-bee, Apple & Google involved https://en.m.wikipedia.org/wiki/Thread_(network_protocol) https://en.m.wikipedia.org/wiki/Thread_(network_protocol) I haven’t looked into mesh networks in a few years. Back then, Germany seemed to have a few open source mesh projects.
