I’ve a VLAN dedicated to IoT devices and, of course, HA can’t discover them. Is it possible have them discovered by HA via MQTT? Create them manually it’s a pita because they’re a lot and I would have to create sensors/switches + battery level + RSSI Thanks!
This is the right way!
VLANs typically can only cross communicate via the gateway, most broadcast discovery protocols don’t get routed via the gateway (because its not considered local), and while you can get the gateway to repeat some traffic, its very brittle… lots of network stack developers made assumptions about broadcast packets being on the local network segment.
