Reconfiguring home-assistant app container

Hi all,
as I would like to connect Shelly buttons I need to customize home-assistant container in order to expose the port 5683.
It seems that the following configuration in container is missing
- “5683:5683/udp”
I built umbrel image by myself but it’s not clear where to intervene to configure home-assistant container.
Any suggestion?

Hi ddozza, did you ever resolve this? I migrated my installation to my umbrel node but my events aren’t registering. Would this be the reason?
