mac addresses on different LANs shows as offline
mbierman opened this issue · comments
I've noticed that when I use mac addresses devices may appear offline when they are not. Best I can determine to reproduce is if the device defaults to offline and restart homebridge . Very soon after, devices on other LANs will show as disconnected when the lookup fails. Leaving it run for a while doesn't seem to fix it.

I don't believe the MAC address lookup will work across LANs?
So I don't know the answer to that. Obviously routers that support 802.1q know how to do that but maybe there isn't a way to to ask the router based on Arp for a different network segment? You could be right that isn't possible unless the plugin is configured to know about local LANs and scans them. Perhaps that's asking too much.
I am going to close this as I don't think there is anything possible to do with pinging ARP on different subnets. This is what IP and routers and for...
