Not able to discover lifx bulb / brand new install on truenas, not sure if I'm doing it right (thelemmy.club)

Hi everyone

I decided to give home assistant a go as I'm tired of the lifx app. Plus, it means I can move to different brands of lights and control it on the same app.

I am not overly tech savvy but I know enough to operate my TrueNAS server for my needs. That being said I'm always learning and emjoy it.

I installed it through the truenas apps page (basically just docker). Install was successful, I created a user account and logged in on my phone through the app. So far so good.

I went to search for lifx bulbs but it's not finding anything.

I'm wondering, have I missed any steps to ensure HA is able to discover bulbs?

Any advice appreciated

Thanks for your message

Here's my settings for network10000204371000020435

If ypu can see anything wrong please let me know, I'll have another Google and see if I can find the issue

Just learned last week that Docker can't receive UDP traffic unless you forward it explicitly. If the bulbs use UDP for discovery, that would be your issue. Try the host networking mode

From my searching, there should be a checkbox called "Host Network" that you can tick in order to put the container into host networking mode.

I think it's this setting here. Under network do I just write host

Seems I was off the mark, as TrueNAS does things differently than pure Docker. According to this thread you need a bridge network and/or to convert Home Assistant to a TrueNAS custom app to get the host mode checkbox.
