Having problems getting the Govee lights local integration working

Configuration

Thank you! IGMP snooping was my problem.

thank you but it’s already OFF by default on my UDM SE :confused:

Running 2025.10.1 in a K3S cluster and a UDM SE. My Govee lights are on the same vlan as my K3S host. Was experiencing the lan discovery issue as well. I was able to solve this by enabling hostNetwork on my helm template.

spec:
  hostNetwork: true
  dnsPolicy: ClusterFirstWithHostNet

Running 2025.10.1 in docker. Previously Govee lights worked perfectly with official integration on HAOS. Moved HA to docker then Govee lights could not be discovered. Container runs in host network mode and is in same VLAN as Govee light. Fixed by opening port on firewall:
firewall-cmd --add-port=4002/udp --permanent
firewall-cmd --reload

I just had to work through this problem on my new Govee outdoor lights as well.

The problem was simple. Nowhere is it ever mentioned (that I’ve found) but you need to go into the app and enable “LAN Control”. After that it instantly found my lights and configured correctly.

Thanks for the hint, just used the same strategy. Worked.
