A Nebula HACS integration/add-on

@frenck has done an amazing job creating wireguard and zerotier solutions for Home Assistant.

I’m looking to use Nebula to set up the overlay network for my home and cloud setup, as well as managing ingress into Home Assistant and other devices on my network under my control.

It exists somewhere on the spectrum between ZeroTier and WireGuard, in that it’s fully “on-prem” managed, but has all the dynamic endpoint discoverability advantages of ZeroTier, and is well supported across a variety of OSes and architectures.

Looking at the source of the wireguard and zerotier add-ons, it seems feasible to adapt the same/ similar approach to get nebula support and management as well.

There is also Tailscale that has been added to HA, by Frenck, I believe. It is super simple, and works well. HOWEVER, it does rely on a central server, and is not open source, like Nebula. I would also be interested in Nebula integration.

I’d love a Nebula integration too - I have it set up on a few devices already and it’s awesome!!

I got started on this. It’s still in very heavy draft form but is basically functional. https://github.com/mr-ransel/addon-nebula

It’s incredibly rudimentary and not tested yet, but with some iteration I think it will end up working pretty smoothly as a substitute for wireguard, zerotier, or other alternatives for an encrypted overlay network.

For anyone following along, I came back to it today and this is functional enough (though still a pain to configure) that I’m considering swapping to using it to manage my network access full time into my house and not using supervised HA anymore, since this was the last thing keeping me from switching to HassOS. Now that it works I can start making it configurable and automated in earnest which should be much faster progress than before, if nothing else because it’s more rewarding than ‘Did that fix it? No. Still broken…’
