Zigbee Went Down With My WiFi? (lemmy.tf)

The other day my WiFi network went down and with it, I lost access to my Zigbee network?* Is this normal or is this a sign of a massive issue?

*When I checked the Raspberry Pi running Home Assistant, all devices showed as unavailable.

How is your coordinator linked to your home assistant?

For example if you use Zigbee2MQTT and you have either Zigbee2MQTT or Homeassistant pointing to the internal ip of mosquito (192.168.1.11 for example) and your router goes down (with dhcp), it's possible it cannot communicate anymore.

This isn't the case if it's all running on the same box using localhost as address, running it in a docker network or when you run ZHA however.

Ding ding, here's the winner I'd bet

I think it didn't work when I tried localhost, so used pi5.local

that uses mDNS, which in some cases requires your router to be online to be able to resolve it to a ip. If part of your internet disruption was your router going down, it would explain the issue

Ahhhh, that explains it then. I so need to hurry up and build my router.
