Apple Home/HomeKit on a isolated network results in very slow IoT devices

giuliomagnifico · January 21, 2023, 9:37am

Thanks again for the info,

Yes now I corrected this, I'm using Avahi only on the Homebridge Raspberry PI and I've edite the .conf file, now it's using the reflector but I'm still unable to get the stuff working inside the iot LAN!

No, on the firewall of the AP, where is the "iot" interface, the Avahi host (aka Homebridge Raspberry PI) doesn't have a firewall, so this is correct.

If I run a tcpdump on it on the port 5353 I see the queries, everything is correct but I can see only the devices in my main subnet 192.168.1. and not the devices in the iot subnet 192.168.4.

This is the issue, I'm not able to propagate the Avahi mdns in the subnet. If you have suggestion for this issue... I'm trying anyway.

Because all it's working on the iot subnet/interface, Alexa and HomeKit, only they are super slow because they're routed from the "cloud" instead of reply inside my LAN. That's why all is slow to respond, and that's why I need an mDNS to work in the iot subnet

EDIT: oh forgot, if I disable the firewall on the AP, Avahi lookup on the subnet is still not working. I don't know... I'm going crazy and I can't debug the mDNS packet with wireshark because I don't see it, because the devices are not discovered, so when I press a light ON button, there's no device where to send the packet and obviously no packet sent!

Edit2:'ve I tried also this

[server]
allow-interfaces=192.168.1.4, 192.168.4.1

But this broke Avahi, it should be an interface not a subnet obviously

spence · January 21, 2023, 2:05pm

On the Homebridge Raspberry PI:
What is the network interface for 192.168.4.x?

Does ip addr show show that [sub]interface up and normal?

Does ip neigh show show the mac addr for devices in the 192.168.4.x network like 192.168.4.120?

What is the output of tcpdump -D?

Please share the tcpdump command you are using to view mdns traffic.

Thanks.

giuliomagnifico · January 21, 2023, 2:52pm

Sorry but I've changed to .5 instead to .4 (just because it easy to remember 1.5 and .5.1).

Anyway

No...only the 192.168.1.x devices

What is the output of tcpdump -D?

pi@homebridge:~ $ tcpdump -D
1.eth0 [Up, Running, Connected]
2.eth0.2 [Up, Running, Connected]
3.any (Pseudo-device that captures on all interfaces) [Up, Running]
4.lo [Up, Running, Loopback]
5.wlan0 [Up, Wireless]

9.nfqueue (Linux netfilter queue (NFQUEUE) interface) [none]
10.dbus-system (D-Bus system bus) [none]
11.dbus-session (D-Bus session bus) [none]

And the on the avahi-daemon.conf I don't have specified any interface, so it should advertise on both eth0 and 0.2 but the curious thing that I noticed only now, is that for the Homebridge UI there's only the ipv6 on the second interface.

Also the ip address show doesn't show the ipv4 but i have configured it in dhcpcd.conf

interface eth0.2
static ip_address=192.168.5.2/24
static routers=192.168.1.2
static domain_name_servers=192.168.1.4

hmmm I'm tired to debug

spence · January 21, 2023, 3:33pm

Hopefully, once you get your host running avahi directly connected to vlan1 and vlan2 (homekit devices) all will work. Are all your PCs, phones, tablets, homeHub etc on vlan1 (192.168.1.x)?

You need the vlans to be trunked between homebridge and your switch device. Setup/verify the vlan trunking config on both sides.

Maybe you need to switch the config for vlan1 on homebridge.
I'm thinking instead of 192.168.1.5 on eth0 and 192.168.5.2 on eth0.2, move 192.168.1.5 to eth0.1. Research this for the os running on homebridge.

Be careful about maintaining connectivity to homebridge if you make changes. Use serial console or keyboard and monitor console as appropriate.

Did you choose to not put avahi on your r4s router for security reasons or something like uncertainty of which package to install?

giuliomagnifico · January 21, 2023, 3:57pm

No! My idea was to use Avahi (reflector) on it but it doesn’t work! I’ve tried all the afternoon yesterday.

My idea is to delete the other interfaces on the Raspberry PI/Homebridge and use Avahi on the R4S or WAX206, in this way

R4S router 192.168..1.2
Homebridge 192.168.1.5
WAX206 AP 192.168.1.3
2.4ghz WAX206 AP as “iot” WLAN with different subnet 192.168.5.x and Avahi reflector
Firewall rules on WAX206 AP to forward request from 192.168.5.x to main subnet .1.x

But the Avahi reflector doesn’t work, all the rules are working, if I join the “IoT” SSID with my iPad/iPhone I get the 192.168.5.x DHCP, I can browse online (port 80) but not the local network on .1.x as I want.

Everything is working
As I want except for the HomeKit/Homebridge devices that are working but super slow.

Maybe i have to set the rules on the firewall of the R4S but since I’m using the wireless interface “as a VLAN”, I don’t have the zone/configuration inside the firewall of the R4S

Maybe it would be easy to setup a VLAN on the R4S and use it as a network interface assigned to the wireless interface on the WAX206 ?!

Anyway thanks for the help !

spence · January 21, 2023, 4:26pm

EDIT: If WAX206 is the router between 192.168.1.3/24 and the IOT network 192.168.5.1/24 then it might be a good system for the mdns reflector.

giuliomagnifico · January 21, 2023, 5:11pm

Exactly what I thought, but instead this setup isn’t working. I'd lke to keep the things easy, but I don’t know, maybe I configured something wrong with the interfaces or firewall or I don't know what...

Here are the few interesting configuration, if you spot something wrong or have an idea!

(remember that if I join the "iot" wifi network from a iOS device, everything is working as expected. Only the propagation of mDNS is not working.

Network

config device
	option name 'br-lan'
	option type 'bridge'
	list ports 'lan1'
	list ports 'lan2'
	list ports 'lan3'
	list ports 'lan4'
	option ipv6 '0'

config interface 'lan'
	option device 'br-lan'
	option proto 'static'
	option netmask '255.255.255.0'
	option gateway '192.168.1.2'
	option ipaddr '192.168.1.3'

config interface 'guest'
	option proto 'static'
	list ipaddr '192.168.3.1/24'
	list dns '192.168.1.4'

config interface 'iot'
	option proto 'static'
	list dns '192.168.1.4'
	list ipaddr '192.168.5.1/24'

Wifi

config wifi-iface 'default_radio0'
        option device 'radio0'
        option mode 'ap'
        option encryption 'sae-mixed'
        option key 'x'
        option ssid 'Magnifico_IoT'
        option network 'iot'

Firewall (DHCP rule is not necessary)

config forwarding
	option src 'iot'
	option dest 'lan'

config rule
	option name 'IoT DHCP'
	list proto 'udp'
	option src 'iot'
	option dest_port '67-68'
	option target 'ACCEPT'

config rule
	option name 'IoT DNS'
	option src 'iot'
	option dest_port '53'
	option target 'ACCEPT'

config rule
	option target 'ACCEPT'
	option name 'IoT 80'
	option dest_port '80'
	option src 'iot'

config rule
	option name 'IoT 443'
	option dest_port '443'
	option target 'ACCEPT'
	option src 'iot'

config rule
	option name 'IoT 5353'
	option dest_port '5353'
	option target 'ACCEPT'
	option src_port '5353'
	option src 'iot'
	list proto 'udp'
	option dest 'lan'
	list src_ip '224.0.0.251'
	list dest_ip '224.0.0.251'

	option src 'iot'
	option dest 'lan'
	option target 'DROP'
	list proto 'all'
	list dest_ip '192.168.1.0/24'

And the avahi-daemon.conf

#publish-resolv-conf-dns-servers=yes

[reflector]
enable-reflector=yes
reflect-ipv=yes

spence · January 21, 2023, 5:35pm

I am focussing on one piece at a time, mDNS.

Please show info on 'iot' lan connectivity on WAX206. (filter any sensitive info)
ip neigh show
ip addr show
ip route
tcpdump -D

giuliomagnifico · January 21, 2023, 5:51pm

Oh thank you very much for the help! Remember that other IoT devices (I mean Alexa, wifi weather stations, etcc..) are working, only the HomeKit devices aren't working (or are very slow to respond from iOS Home app).

Great! Now I see what should be a system directly connecting 192.168.1.0/24 and 192.168.5.0/24

mDNS reflection should be able to work on WAX206.

Test it.
Do a tcpdump -i any port 5353 on WAX206 and the mDNS query on your mac. What shows up?

Since there are devices in the network between multiple routers to some networks...
On your mac:
show ip route
and traceroute 192.168.5.1
and traceroute 192.168.5.210

Any way to show the route table on your homepod?

Thanks,

etc...

From the WAX206 I see all the packets, same on the Mac, but I see only the mDNS devices on the 192.168.1.x subnet. And not on the 192.168.5.x subnet.

I think on macOS the command is

You need to configure the „allow-interfaces“ section in your avahi config and add both interfaces (iot and lan) and uncomment the line.

giuliomagnifico · January 21, 2023, 6:46pm

I've already done it, indeed I've commented it because if it's commented Avahi should listen on all the interfaces, I tried everything:

What should work: allow-interfaces=br-lan,wl0-ap0

And also in this way: allow-interfaces=iot,lan

Both aren't working.

spence · January 21, 2023, 7:48pm

I think the reflector may be working. Notice the Out flag on interfaces wl0-ap0 and wl1-ap0 log lines.

I don't know why there are not any replies though.

Are you sure _hap._tcp.local. is a valid name to query? Did the devices on 192.168.1.x respond to the query from the mac?

I think macs now use ip for setting and checking network parameters. My mac has/uses ip. Legacy tools like netstat may still work. Your reply shows what I wanted to see. Route or no route to 192.168.5.0/24.

Checking the route info is starting on step 2 of debug.

Back to mDNS...
Double check the interface for ssid 'iot' and please do another mDNS query test with your mac only connected to wifi ssid 'iot' on WAX206. and the following tcpdump on WAX206:
tcpdump -i wl0-ap0 port 5353
Capture on the mac and share as well please (tcpdump is likely available but needs to be run with sudo). The capture on WAX206 should at least show the queries but hopefully replies as well.

Thanks

PS - I will be busy with home chores for a couple hours.

Yes but it shows only the Homebridge hubs inside the 192.168.1.x subnet

What you mean for "double che the interface iot"? What I have to check?

Anyway if I've joined only the 'iot' SSID I'm unable to SSH into the WAX206, because -as I want- it's not reachable. If I enable the ethernet adapter on the Mac, I join my main network 192.168.1.x and the output of

tcpdump -i wl0-ap0 port 5353

on the WAX206 is:

Hey, thanks to you! And don't worry, reply when you have the time, you are already helping me a lot!

Now I go back to sleep, here -Italy- is the 1:30 AM (as yu can see from the logs )

spence · January 22, 2023, 3:17am

Thanks for replying so late.

So, WAX206 sees mdns traffic on both 192.168.1.0/24 and 192.168.5.0/24 networks. I was hoping to see a clear indication of a query and the reply but nothing like that is clear to me. I'm not experienced with mdns and your traffic does not look like the example I saw on someone's blog.

Depending on what your last reply was, I was thinking of asking you to put your mac on a lan interface on the WAX206 but it looks like you did that already.

If no-one else with avahi experience replies, it may be good to open a new thread with a title specific to this mDNS/avahi issue.

The next part I might be able to help troubleshoot is TCP connectivity to smart devices through the WAX206 (AP/router/firewall). Sometimes devices don't like routing setups like you have.

Does your r4s have a route table entry for 192.168.5.0/24 ?
Please show ip route show from your r4s.

If it does, Also on the r4s do traceroute 192.168.5.1
and traceroute 192.168.5.198 or some device IP you know is alive and should reply.

With your current setup, you might need to add the route to network 192.168.5.0/24 via 192.168.1.3 to all the devices in the 192.168.1.0/24 network. That might be fairly easy with a DHCP option.

An alternative would be to move the routing/firewalling for 192.168.5.0/24 to the R4S and trunk it back from the WAX206. These ideas for changes are only if needed though.

...till Sunday...

giuliomagnifico · January 22, 2023, 8:03am

Oh thanks to you for the reply, yes this is my issue, I'm not saying that Avahi isn't working/running, I'm saying that this setup doesn't work for some reasons and I can't figure out why, also becase *is working, onsly *superslow.

No but I created it now, just to test. Althought I created it "random", I have no idea well how to do, because the R4S should be "transparent" for this, it should only route the packets to the WAX206/AP, indeed now I have created it but I still can't use Homekit

root@R4S:~#

Instead from the WAX206 yes

root@WAX206:~# traceroute 192.168.5.116
traceroute to 192.168.5.116 (192.168.5.116), 30 hops max, 46 byte packets

And obviously also from the Homebridge server the R4S is blocking the route.

pi@homebridge:~ $ traceroute 192.168.5.1
traceroute to 192.168.5.1 (192.168.5.1), 30 hops max, 60 byte packets

 2  Nanopi-R4S (192.168.1.2)  3099.041 ms !H  3098.932 ms !H  3099.533 ms !H

How can I make the 5.0 subnet available via the router/r4s?

You mean this on the R4S?

config route
	option interface 'lan'
	option target '192.168.5.1/24'
	option gateway '192.168.1.3'

Yes I can also do it, is the same.

giuliomagnifico · January 22, 2023, 9:12am

Ehy wait wait, maybe maybe I succedeed Not all is working because I have to investigate on something, but the lights are super-responsive and other stuff are working.

I added a new routing table to the WAX206 as you suggested:

config route
	option interface 'LAN'
	option gateway '192.168.1.3'
	option source '192.168.1.2'
	option target '192.168.5.0/24'

So

root@R4S:~# route -n
Kernel IP routing table

192.168.5.0     192.168.1.3     255.255.255.0   UG    0      0        0 br-lan

And now I'm able to trace route/ping/whatever the devices on the .5 subnet and also the mDNS packets are going through.

Home@MacBook_Air ~ % ping  192.168.5.1

Yeah it's a bit slow more than 1 sec for a cabled LAN but it doesn't matter at the moment.

If I connect to the iot WLAN with my devices I'm getting the DHCP address, I'm able to browse online via port 80 but not to reach the main LAN at 192.168.1.x, the HomePod is still on the main LAN/WLAN but things are getting routed correctly now.

The only thing that isn't working is the Netatmo thermostat relay, I have no idea why because the Weather Station is working, maybe I have to try to add it again to HomeKit.

giuliomagnifico · January 22, 2023, 10:11am

Ok now everything is isolated, is working etcc..

BUT

Not the Netatmo Thermostat Relay and Weather Station I've added them again to HomeKit but nothing, so I searched on the Netatmo and I've found this https://helpcenter.netatmo.com/en-us/smart-thermostat/connection-wi-fi-radio/advanced-network-troubleshooting-guide

Please check if your router has any firewall / port filtering. If so:

Open the 25050 port (TCP).

Assign the Wi-Fi module a static IP with its Mac address.

Now I've done also it and the Thermostat and Station are now connected and I can control them via Netatmo app or website BUT not from HomeKit I don't know what's going on with Apple protocols but these issues are mind blowing!

Edit: I solved the DHCP issue, I had to create a rule in order to reach the .5 subnet from the main LAN

config zone
	option name 'lan_to_iot'
	option input 'REJECT'
	option output 'ACCEPT'
	option forward 'REJECT'
	list network 'lan'

config forwarding
	option src 'lan_to_iot'
	option dest 'iot'

Now the only issue that I can't solve, is the Netatmo devices that are not working with Home app, I opened a new thread: Netatmo HomeKit native devices, not able to update iOS Home app when isolated (but work online/using Netamo app)

spence · January 22, 2023, 3:20pm

Brrr - that is chilly! my house is at 19.5°C and I wear a hoodie sweatshirt when I sit for a while.

YAY!!! I'm glad your network is working much better!

For debugging ideas:
Questions -
Did the Netatmo thermostat relay never work with Homekit yet or did it stop working with recent network changes?
Did you do a full reset on the thermostat or just re-add it to Homekit? Try a full reset if you didn't do that.
Are the Homekit keys still valid? If the keys are different for each device, remove old Homekit keys for the thermostat and re-add them.
Do you have logs to view in Homekit? If so review them for info on communication problems.
Does access work via iCloud? (disconnect your iPhone from your lan so HomeKit runs as remote access.

For direct Homekit access - Make sure you understand the communication path.
Does Homekit on your iPhone or Mac talk directly to to the Netatmo themostat or does it always use the Homekit Hub (or some other set of components).
What L3 components are involved? Check routing/firewall settings. Do a packet capture to look for packet drops (blocks).
Move the Netatmo thermostat to the main lan (192.168.1.0/24) and re-add it in Homekit. Does it work there? If it does then look at communication issues related to routing/firewall.

When making changes like moving the thermostat, make sure Homekit and your routers and switches learn the change and knows the new connection info.

To verify where the thermostat is on the network, look at arp on your routers and match the thermostat mac address to the IP address and Device.

root@R4S-wrt:~# arp
IP address       HW type     Flags       HW address            Mask     Device
192.168.31.100   0x1         0x0         cc:95:d7:bd:ef:8d     *        sw_switch.31

(Sample from my router)
.
.

Do you mean the Homekit app sees them at .1.x or the operating system does?
On the OS, look at the arp cache to see if it is local or not. Check on the routers to verify where the devices are.
If the Homekit app sees them at the old address then get Homekit to update the device info. Flush caches or rediscover or remove/add the problem devices.

Well, those are my ideas at this point! Please let me know how it goes or ask more questions if you want.
