Home Assistant Community Add-on: ZeroTier One

CBRHerms · April 5, 2019, 2:34pm

To those who have an OVA based HassOS install running on Proxmox / VMWare / Hyper-V, I ended up setting up a small zerotier VM (1vCPU, 512MB RAM) that is now running quite nicely as a gateway to my home LAN (rather than just my HA instance).

Loosely followed these instructions as i needed a lil extra clarification:
https://0wned.it/2017/12/04/building-a-zerotier-bridged-network/

Couple of things to note:

Working curl installer:

curl -s https://raw.githubusercontent.com/zerotier/ZeroTierOne/master/doc/contact%40zerotier.com.gpg | gpg --import
curl -s https://install.zerotier.com/ | gpg --output - >/tmp/zt-install.sh && bash /tmp/zt-install.sh

Adjust interface device to your nic’s name as shown in ifconfig
Zerotier device will likely differ from zt0 - can be found via ifconfig after installing Zerotier

Apart from that, went relatively smoothly

each host you want to reach needs the zerotier client installed.

as I understand it, you cannot use zerotier to access, say, an ip cam or xiaomi bridge on your local network

however, I don’t see why you couldn’t install zerotier on your windows/linux machine and once in control of that machine, use it control something else on the local network

You can with the method i mentioned above but it requires a VM being set up, or setting a device on your network with the client and then bridging.

Can’t be done at present using the addon though, of course.

I am having the same issue…All my devices on my zerotier VPN can access and ping each other, but none can access my HA setup. The ZeroTier management portal shows all devices (including HA) as being connected, but nothing can access HA.

@frenck Hi any luck with ZeroTier for those of us using VM’s do you think you can get it to work?
I have tried Linux and OpenWRT to use as Layer 2 bridges but just falls on its face in my setup as I use Pfsense with VLAN’s and can only ever get ZeroTier network to talk to the bridge itself.
I also looked into ZeroTier for Pfsense but nothing promising yet.

CBRHerms · April 11, 2019, 1:10pm

Frenck submitted a pull to the HassOS repo here: #390

Looks like it’ll be in the next release of HassOS so may just have to wait til then?

Raz0rsEdge · April 11, 2019, 1:12pm

Good to know would be super useful.

Interesting! This is now working perfectly for me… how odd. My HA NUC only has an IPv6 address and port 443 open and I use a reverse proxy (caddy) and I can connect to the ZeroTier One IP address on port 8123! This is perfect! Secure connection via the VPN it creates.

fernandex00 · April 23, 2019, 11:37pm

I’m notice that after using zerotier to access home assistant remotely, in my phone, home assistant get unresponsive, and I have to reboot the hassio docker to get home assistant running again, any thoughts?

DavidFW1960 · April 23, 2019, 11:40pm

I have noticed nothing like that.

denver · April 25, 2019, 7:49pm

Cant get this to start:

System Health
arch	x86_64
dev	false
docker	true
hassio	true
os_name	Linux
python_version	3.7.3
timezone	Europe/London
version	0.92.0

mode	storage

config:

{
  "networks": [
    "1c75fc193e19840f"
  ],
  "api_auth_token": ""
}

As soon as I click the ‘Start’ button, it turns red and refuses to start.

Can anyone help?

DavidFW1960 · April 25, 2019, 11:05pm

Well the config is red =error. It won’t save if there’s an error. So probably the network ID is too long or too short.

denver · April 26, 2019, 6:58am

I made the network id up David whilst posting, the original one is not red in the config, the same as the “” in the api_auth_token. Its just strange that it refuses to start at all, not even showing any info in the log after refreshing. I wondered if its because its running in Proxmox.

Is there away to test ZeroTier to make sure the network is working

DavidFW1960 · April 26, 2019, 7:19am

You need to authorise it in ZeroTier site…

denver · April 26, 2019, 7:25am

Its says that on the ZeroTier site but not sure how to:

DavidFW1960 · April 26, 2019, 7:34am

The nodes will pop up and you can authorise them. They will be displayed below your screenshot.

frenck · April 26, 2019, 7:48am

This means the Hass.io supervisor is not able to start the add-on.
For information on what is going wrong you need to go to: Hass.io panel → System tab → Look at the log there.

Yes, Proxmox is an issue.
