This is what I’ve been using.
192.168.10.1 is my main LAN.
HA main address is 192.168.10.6
192.168.10.4 is Pi-hole.
Valn 20 is where I keep all IOTs on opnsense
HA vLan 20 address is 192.168.20.3
Should just remove the gate way from this interface then for mdns and HA discovery to work?
Like you said, I was sometimes accessing vlan20 HA instance from my main LAN PC which is wrong as you mentioned.
If you are using the GUI of Home Assistant for network definitions, there is a way to set up an empty gateway easily: just enter “0.0.0.0” in every gateway field in each network interface (VLAN or not) that is not the main one (the one that you open the GUI in and usually the one that is set up first) 
Thank you. Which network adaptor should choose in my case? The vlan adaptor or the default?
Obviously it depends on what you are trying to achieve, but taking into account your description, your vlan adaptor is the segregated one, so it should not have a gateway nor a dns set up (HA does not need them in fact). If this is correct, then what you should have in HA network config is:
Main LAN
Network interface is ENP0S31F6.
Network is 192.168.10.0/24
HA main address is 192.168.10.6/24.
Gateway for this network is 192.168.10.1
DNS for this network is 192.168.10.4
VLAN
VLAN network interface is ENP0S31F6.20.
Network is 192.168.20.0/24
HA address is 192.168.20.3/24.
Gateway for this network is 0.0.0.0
DNS for this network is 0.0.0.0
Go to the terminal and run
ip r
output should be similar to this (some elements may be different, as I’m just guessing here):
default via 192.168.10.1 dev enp0s6s31f6 metric 110
172.30.32.0/23 dev hassio scope link src 172.30.32.1 (these are HA specific)
172.30.232.0/23 dev docker0 scope link src 172.30.232.1 (these are HA specific)
192.168.10.0/24 dev enp0s6s31f6 scope link src 192.168.10.6 metric 110
192.168.20.0/24 dev enp0s6s31f6.20 scope link src 192.168.20.3 metric 110
ha network info
should produce:
- connected: true
enabled: true
interface: enp0s6s31f6
ipv4:
address:
- 192.168.10.3/24
gateway: 192.168.10.1
method: static
nameservers:
- 192.168.10.1
ready: true
- connected: true
enabled: true
interface: enp0s6s31f6.20
ipv4:
address:
- 192.168.20.3/24
gateway: null
method: static
nameservers:
- 0.0.0.0
ready: true
That’s it!
Thank you so much for taking the time to explain in detail and provide examples.
I got the exact same results after deleting the Vlan gateway and DNS.
Again, Thank you so much.
Anyone else having an issue with your adapters no longer showing up in HA? I’ve had these setup for months, but now no longer seem to want to show up within HassOS. I’ve tried deleting and recreating
Wondering what changed causing adapters not to be available to the HA container? 
seems it maybe something with os 11
Looks like there was an interface rename within the HA container from eth0 to end0
As well you can now use ‘ha’ to create a new network vlan interface immediately without rebooting and without the use of nmcli
ha network vlan end0 3 --ipv4-method static --ipv4-nameserver 192.168.2.6 --ipv4-address 192.168.3.14/28 --ipv4-gateway 192.168.3.1
I have Home Assistant installed on a VM in Proxmox. In my network, I have several VLANs configured; the HA is on the server VLAN, and I have IoT devices on another VLAN.
Yesterday I bought an Aqara FP2, which only allows linking to HA through HomeKit. Since it was in two different VLANs, it was impossible for HA to detect it. I solved it by configuring an additional virtual network card in Proxmox for HA. I assigned the IoT network to that card, and now they can see each other. It seems like a good solution because this way mDNS works on the IoT network, and HA can access it.
Could you please share detail with newbie? Thanks!
Are you using HA in proxmox?
Thanks to @cr0muald0 's excellent tutorial I was able to create a second interface for my HA Yellow to connect to devices on my IoT VLAN on my Unifi-controlled network. I was able to configure my first device (a Sonoff Dual R3 relay) via the ESPhome dashboard, where it shows as ‘online’.
The problem is that HA doesn’t auto-discover the device. It does not show up in the Integrations dashboard. I am able to add it manually using the IP address of the device, after which all controls function as expected. While this will probably work fine for a relay which will be online 99.9% of the time, I would really like auto-discover to work properly for future devices that may not be present in my network all the time and may receive different IP addresses.
I’ve read a lot of similar issues, both on the HA forums and on other sources, but none give a definitive answer for my problem. Some suggest that mDNS network traversal should be allowed but that would be necessary only if my HA device was in a different broadcast domain. Since I added the VLAN interface to HA, that should not be necessary. Of course I tried that, but it did not work. This seems to describe my issue but it doesn’t describe exactly what he did to resolve the issue and it received no replies.
Can anyone give me some pointers on where to look next to be able to diagnose this issue?
Hey @gerritgleufhoed, so you are saying the device is in the same network segment, right? That excludes the mdns problem. What integration are you using? As far as I know, the auto-discovery only works with Tasmota flashed devices or ESPhome integrated devices, but you did not mention that clearly. Did you flash your relay with Tasmota (I’m guessing no)? Are you using the ESPhome control system? And you have the ESPhome integration installed? Only then it might auto discovery ESP flashed devices, in my understanding (my Sonoffs are all Tasmota flashed and mqtt’ed) 
Sorry for not stating that clearly. Yes, the relay is in the same network segment as the newly added IoT VLAN interface in HA.
I have installed the ESPhome integration into HA and flashed ESPhome to my Sonoff relay (using the web.esphome.io dashboard wizard because I’m not yet running HA on HTTPS). When looking at the ESPhome HA dashboard (not sure if I’m using the right terminology here), the relay shows as ‘online’ and I’m able to send OTA updates to it. But it does not show up as a device with sensors and switches in HA, unless I add it manually through an IP address. After doing this I can control the relay without any problems.
From what I read, ESPHome requires mdns to function properly, so you don’t have to specify an IP in Home Assistant. How did you configure your ESP?
The mdns component makes the node announce itself on the local network using the multicast DNS (mDNS) protocol.
Both Home Assistant and the ESPHome dashboard use mDNS to identify the IP address of all ESPHome nodes on the network. If mDNS is disabled, they will no longer be able to automatically find your devices. It may be necessary to use a static IP for all nodes and to enable the ping option in the Home Assistant add-on.
It is recommended to leave mDNS enabled.
mdns:
disabled: false
Then Home Assistant should be able to get the node’s IP (from mDNS and create the sensors automatically). Remember, either you give the node a static IP, or if you are using DHCP server, a fixed lease.
Read the Notes on disabling mDNS here: https://esphome.io/guides/faq.html#notes-on-disabling-mdns
and you will understand better the trouble of having a misfunctioning mDNS 
Thanks for the reply, but I did not specify anything regarding mDNS in my ESPhome device yaml. Because mDNS is enabled by default, it should announce itself to the ESPhome dashboard instance, which should make it available to HA. Sadly, the second part of that sentence is not happening.
From the FAQ:
Online status detection in ESPHome’s dashboard by default uses mDNS
Since the ESPHome dashboard shows the relay as online, I must conclude that mDNS is working properly. It must be something related to announcing the device’s presence to HA that is not functioning. I could use tips to start diagnosing this further.
I see. According to what you are describing, it looks like the node is added to the dashboard but not creating the sensors in HA, as it should. For that to happen, it needs to have the node’s IP properly configured, which should be configured automatically, but apparently not always. Check this thread here to see if it helps:
I had read that thread already. The quote solution unquote in that thread is to just add the ESPhome device integration manually via the IP, which works in my case as well but should not be the go-to route to add devices.
One thing I did notice is that I don’t have the captive_portal or fallback AP configured in my device setting as I don’t see the point: the device should be able to connect to the configured wifi or fail, in which case I have to fix the configuration. I cannot image that being the cause of the autodiscover failing in HA, but it’s worth a shot.
I’ll try to get some log output of the device to compare it to the log output in the thread you linked to see if I see similar output.
I read somewhere that ESPhome auto-discovery sometimes takes a long time to find (around 5 minutes), so you can always try re-adding the node and wait for a longer period (over a night, maybe) and check later the logs if the API is somehow active and interacting with HA, as it should.
Another thing to double-check is the wireless AP configuration: if it’s not filtering communication between clients (some APs have client isolation by default turned on, especially for non-standard/custom /guest wireless networks).
If you could share your node config (redacted, obviously), it might be easier to check some overlooked config problem, although that does not seem to be the cause…
The VERBOSE logs for my ESPhome relay node doesn’t give a clue:

Not sure if that helps, though.
I don’t see anything wrong, maybe you can increase the verbosity of the log in the node for the desired components and check if there is more info. Something like this:
logger:
level: INFO
logs:
mdns: DEBUG
api: DEBUG
Another option is to check the API component and set rules to log when the connection occurs (if it occurs at all) and see what happens:
Like here in the example:
The other possible way is to try and ping or resolve the mdns address from Home Assistant to see if it’s working, given the fact that ESPhome integration needs mdns connection for auto-discovery to work.
As I don’t have it installed myself, it’s difficult to be more helpful
I got it working! And I think I know what the problem was:
When you add a new VLAN interface through nmcli, it allows the HA instance to communicate with the VLAN and its devices (hence the ESPhome dashboard finds the relay without issue), but it does nothing with the HA configuration itself. HA is configured to Auto Configure the network adapters the integrations will use by default and it seems that it does not detect an added VLAN adapter automatically.
I found another thread a few days ago which hinted at the solution but didn’t state it explicitly. I hope this will help others who run into the same issue. You simply need to go to Settings - System - Network, go to the Network Adapter settings, unselect Auto Configure and select the adapters that are detected (in my case: end0 and end0.30). You will need to reboot the HA device manually for this to take effect.
By reverting back to the Auto Configure setting, I replicated my problem and the ESP node is not detected anymore. This could actually be worth a bug report, what do you think?
