#Wifi Mesh, router connected devices are unavailable to HA?

I have an Orbi mesh router. It has a satellite and a main router. The HA server is using wired connection to the Satellite. All devices that connect to the satellite are visible to HA. But anything that connects via wifi to the router are not visible to the HA server.

This is a new problem, maybe in the last week or two. Before this, never had this issue
HA and all components are latest versions.
Router and satellite are on latest firmware.
I can see in the router UI that all of my IOT devices are connected, some to router, some to the satellite, and anything on the satellite is visible to HA, those on the Router are not visible to HA.
I have tried rebooting everything. HA, Router, Satellite, and literally turned off the entire house power for a few minutes to try to reset everything.
arp -n command on the HA server, through SSH shows ALL of the devices that are connected to the router, and those connected to the Satellite.

Any thoughts on what I can do to debug this? The devices are definitely connected to the wifi network, but HA appears to be blind to the devices on the router, and can see devices on the satellite.

  1. All the devices are on the same subnet?
  2. You don't have the option for wireless (client) isolation enabled?

All are on same subnet. DHCP is handled by a pihole server, and all devices have MAC address mapped to a specific IP.

I have not found any option for wireless client isolation in my router.

I'm going to go out on a limb and guess that the mesh doesn't pass mDNS (and probably some other broadcast) traffic

T he router has not had a firmware update since June. This was working fine for years on this router (since 2021). This just subddenly started happening about a week ago.

HA's "discovery" is (mostly) done using mDNS (and some other broadcasts), so that failing says that HA isn't seeing that traffic any more

I have also started up another satellite on the network. If devices connect to either satellite, then they are visible to HA, wired to Satellite 1. But, anything that connects wifi to router, HA cannot see it. Weirdly, doing arp -n in ssh session on the ha server, all devices are listed, including the ones connected to Router.

#

The devices that I am focusing on use MQTT. These devices do not use mDNS. There is no mDNS entry for any of them; neither the ones that are connected to the satellites and working, nor the ones connected to the router, and HA is not seeing. They are programmed in such a way that they use mqtts, and I set them up with the mqtts ip address which is the HA server. If I bring one of these devices close to the router, then it connects to router, and HA ignores it. If I move it close to either satellite, then HA sees it and can control it.

#

But, other devices that do use mDNS are also invisible to HA if they connec to router.

Well, MQTT devices not being "seen" means that the messages aren't reaching the broker

#

Are you sure that they can reach HA from the router?
