Issues with Govee Local and multiple VLANs

[dougmaitelli]

The problem

Local integration with govee_local seems to have some issues with multiple local VLANs.

I originally raised this problem in #111597 but was able to get it to work again. Now been a while that is all broke again and refuses to work 100% of the time.

I don't know what exactly is the problem, but I assume HA is not using the correct interface (my installation has 3 interfaces, each in a different VLAN) to send the multicast to the lights. For now I reverted back to use the custom integration from HACS which works flawlessly https://github.com/wez/govee-lan-hass, would be nice if the native integration could handle this scenario like the custom one does.

core-2024.4.3

I'm having a similar issue with the Govee integration as well.

My IoT devices are on a separate network that is firewalled from the rest of my devices. My HA install does not have an interface on the IoT network. Because of this, the Govee integration is unable to discover them.

There is no way to enter the IP of the Govee devices. As a result, the integration will not start.

In my case it used to work when the integration was released, then it stopped, started to work again and now it does not work at all.

Hi @dougmaitelli,
nothing has been change in that part of the integration since the release, but I'll look into it.

Having the same problem discovering two new H6072's. Today is the first day I tried as I just got them.

• Followed all available documentation.
• They are on an IoT VLAN separate from home-assistant but I have multicast spanning many VLANs for other devices with IGMP/IGMP Sooping on a Cisco fully licensed switch. Other multicast devices do not exhibit the same behavior (Chromecast, Bonjour, other mDNS, etc)
• LAN mode enabled on lights
• Both lights are connected as shown via my WiFi controller dashboard
• Integration fails to find any devices on my network

Yeah, same thing for me, I do have mDNS replicated between VLANs and other devices don't have issues with local control n different VLANs.

I think this integration has some specific issue with different VLANs that other integrations don't have which should be possible to solve since the custom HACS integration for Govee doesn't show the same issue.

Hi,
I'm investigating the issue with multicast and multiple VLANS. There is a possible fix, but I didn't test it yet.

Thanks @Galorhallen, I can definitely help you test it if you need.

Having the same issue. Can't wait for a fix!

Hey @Galorhallen, did anything change around this on version 2024.5.5? It suddenly started to work for me again.
Only 2 things that I changed (in the same day that it started to work again):

• I replaced my Wireless AP to a Wifi 7 one
• I updated HA to 2024.5.5

[dougmaitelli]

Another update, stopped working again after updating to 2024.6.0 😭
