Hey there @mammuth, @aarondavidschneider, @chemelli74, @mib1185, mind taking a look at this issue as it has been labeled with an integration (fritz) you are listed as a code owner for? Thanks! _{^{(message by CodeOwnersMention)}}

I have the same problem with a 7590..

[kongo09]

The discovered devices are all on LAN5 which is the internal guest network. The missing devices are all on LAN3 which is the main network.

More info on your scenario are needed.

Same issue here. I miss about 160 devices from at all 190 devices.

Modell: FRITZ!Box 7590

I recognized that only devices connected to the WiFi of the FritzBox will be shown. Every client connected to LAN is missing. In my case all clients connected through access points or to my switch.

[kongo09]

Every client connected to LAN is missing

That's interesting. When you connect something to LAN5 on the guest network, does that show up? If yes, then that's the same behaviour that I observe.

[kongo09]

I just did a little test with fritzconnection.

• Using fh.get_active_hosts() I correctly get all my hosts as expected.
• Using fh.get_mesh_topology() as the code of the integration does, I only see the incomplete list.

Is there any reason why the integration is not using the get_active_hosts() call? Or is this a bug in fritzconnection as the Fritz!Box interface in the Mesh setting actually does show all devices, not just a subset.

[chemelli74]

Is there any reason why the integration is not using the get_active_hosts() call?

Two reasons: with the old call you cannot get mesh roles and you miss some additional info like where you are connected, the ssid, etc.

Or is this a bug in fritzconnection as the Fritz!Box interface in the Mesh setting actually does show all devices, not just a subset.

Probably, do you mind reporting it to the library repo ?

[kongo09]

Some further tests show that unfortunately the Fritz!Box 6660 Cable gives an incomplete answer when asked to give the mesh topology. I don't think this is a bug in fritzconnection. The library only delivers what the Fritz!Box delivers.

If there is not some wisdom on the library side of things, the solution would probably be to make use of the hosts that are collected in a dictionary already https://github.com/home-assistant/core/blob/895aee3fb2ca7c0f8d6aeb694019334d47c035e9/homeassistant/components/fritz/common.py#L346

Maybe, having looped over all nodes in the topology, a third loop over the hosts checking self._devices for the macs could add the missing devices?

Let me add my logs for the same problem on a 5490.

same problem on a 5490.

That's interesting. Do I see that right that all devices from LAN1 are missing?

[dieneuser]

I have a similar effect with my Fritz 6660. HA detects my computer via LAN - the status goes to 'home'. Once the computer is turned off, the status remains 'home' until the integration is manually reloaded or HA is restarted.

Not completely. UBNT is available, en is also on LAN1 connected via switch (TL-SG108PE).

[Krocko]

@kongo09 are the changes from your pr working for you without errors? I tried your changes. The devices are all back, but the sensors are missing now.

Another example of the issue:

In my case all devices which are connected via LAN (incl. Repeaters) are not available anymore within the integration. Devices connected via Wifi are available as usual.

All my LAN devices are connected to LAN2 on FritzBox because my central switch in the basement of my house is connected to LAN2. The devices itself are connected to the switch.

FritzBox LAN2 --> Switch Switch --> Repeater 1 Switch --> Repeater 2 Switch --> Repeater 3 Switch --> Raspberry

[LucTs]

Update: Devices connected to LAN port of FritzBox are available in HA.not directly attached to the FritzBox but are behind the switch are not available within the integration.

Summary: FritzBox Wifi -> x devices - available in HA FritzBox LAN3 --> device - available in HA FritzBox LAN2 --> Switch -> x devices - not available in HA

[jgverweij]

In my case, with 2022.2.5 there are 2 more devices available but still not all.

It seems that the WiFi devices which are after the UBNT accesspoint are missing.

Update 1: Fritz -> TP-SG108PE switch -> Ubiquity UBNT accesspoint -> wifi devices

Update 2: But device Dahua, which is connected directly to the switch TP-SG108PE is also not available.

[jaegerschnitzel]

My FRITZ!Box is connected only to one switch where all other devices and APs are connected. I have still only FRITZ!Box itself available as Home Assistant device :(

[kongo09]

are the changes from your pr working for you without errors?

@Krocko Yes, no errors. Are you sure you just applied my PR and nothing else?

However, I did notice that the switches are not working. I'll take another look.

[Rangitoto1980]

My situation seems to be very similar to @LucTs '.

Since updating to 2022.2.x I am also missing some device_trackers which are now shown as unavailable.

• I am using a FritzBox 7560
• Current HA-Versions: core-2022.2.5, supervisor-2022.01.1, Home Assistant OS 7.3 on a RasPi 3
• Wi-Fi connected devices are working fine
• The missing devices are all connected to LAN3 through a switch
• I have several devices connected to LAN2 through an older Fritzbox 7490 and they are detected fine. Looks like there is a dependency to whether devices are behind a switch or router.

[Krocko]

@Krocko Yes, no errors. Are you sure you just applied my PR and nothing else?

Yes. Testet with 2022.2.3 and 2022.2.5

Switches and Buttons working for me.
