Synology + Docker unable to see devices on network

I’m running HA’s Docker image ( on a Synology NAS. It’s running fine, with one problem: it can’t seem to find some devices on the network.

I don’t know if it’s looking only at the 172.x network, or the 192.x network the NAS is on.

I have WeMo and TP-Link devices up and running, linked through Google Assistant. However, HomeAssistant is unable to find any of these plugs. Philips Hue, however, is working.

Is HA via Docker looking on the right network?

If you didn’t set the network mode to host, it won’t discover anything.

Doh! You’re absolutely right. So sorry. I missed that piece (I’m so used to working bridge mode).
