I think there's an actual Roborock integration for HA. I forget if it's official or on HACS, but I've used it and it worked well at the time. It requires cloud, which obviously isn't ideal, but better than nothing IMO.
But according to the FAQ, the vacuums still dont work when they are offline, as they will turn reset their wifi until they are online again.
> When the vacuum is disconnected from the internet, it will attempt to disconnect itself from Wi-Fi and reconnect itself until it can reach the Roborock servers.
Yeah, that’s exactly what happens if I don’t add an exception for it to my iot vlan - it keeps reconnecting to WiFi. Scheduled cleaning doesn’t work without internet either..
I guess I’m not buying the next vacuum until I’m 100% sure it works offline and supports Matter or something..
