Local API not accessible across VLANs

[Nuuki9]

Govee Device SKU

H60A1

Govee2MQTT Version

2025.01.04-f937ceb5

Describe the issue

I have three H60A1s. Of these, one is installed on the same VLAN as the server running Home Assistant and govee2mqtt. Two are installed on a separate, IoT VLAN.

Initially the two lights on the IOT VLAN weren't being discovered. I've reviewed the info at https://github.com/wez/govee2mqtt/blob/main/docs/LAN.md and added the GOVEE_LAN_SCAN variable, to scan using the IOT VLANs broadcast address. At that point the devices appeared in govee2mqtt and in Home Assistant. However, its not discovering or using the LAN API - see the logs below. Only the light on the 192.168.1.0/24 subnet is showing the Local API:

I've checked the following:

• LAN Control has been enabled on all lights.
• I've confirmed that UDP 4001 and 4003 on the lights are reachable from the VLAN the server runs on.
• I've confirmed that UDP 4002 on the server is reachable from the VLAN the lights are on.

I'm not sure what else to check at this point. Any ideas?
