What's the best way to get you the log file?

nimble snow
#

You can Dm it if you like, or put it on the aiohomekit github

clever sinew

#

ok looking at that i see a bunch of ENCRYPT counter=196 without a corresponding DECRYPT - which I think means there is no reply

clever sinew
nimble snow
#

no

#

the ip and port don't change (at least in according to HA)

#

have you restarted since?

#

sort of curious to see if you turn on the logs again what you see

clever sinew
#

Nope, I'll restart and let all the bulbs come back online, then send you the log

nimble snow
#

so if you search for id='70:ac:8f:ed:7e:a4' after a restart, do you see address='fd42:780f:2110:0:13c3:5ff6:67c7:bcc8'

clever sinew
#

It's 100% success when the server has first started up

nimble snow
#

i suspect the answer is that you will

#

in which case the only other clue is the counter

#

when you restart HA that will reset the counter

#

so 2 theories - (1) the bulb never replies if the encryption key is wrong. the encryption key changes on every transmission (based on the counter). so if there is any packet loss, the key will seem to be wrong, the device starts to ignore us

#

(2) the bulb crashes (something we know nanoleaf devices do). on restart, it doesn't remember its active encryption sessions. so it ignores our encrypted packets

#

we can't stop the bulb crashing, and we can't stop packet loss, so all we can do is try to recover if that happens. if we don't get a reply, we have to tear down the encryption session and start again.

#

TBH i thought it already did something like that.

#

will see what i can do

#

don't suppose you know how to edit HA code in place?

#

could probably give you a 1 or 2 line fix to try out if you did

#

on the off chance that you can, it would be in aiohomekit/controller/coap/connection.py, in the function async def post_bytes(self, payload: bytes, timeout: int = 16.0):

        async with self.lock:
            payload = self.encrypt(payload)

            try:
                request = Message(code=Code.POST, payload=payload, uri=self.uri)
                async with asyncio_timeout(timeout):
                    response = await self.coap_ctx.request(request).response
            except (NetworkError, asyncio.TimeoutError):
+               if self.coap_ctx:
+                   await self.coap_ctx.shutdown()
+                   self.coap_ctx = None
                raise AccessoryDisconnectedError("Request timeout")

            if response.code == Code.NOT_FOUND:
                # maybe the accessory lost power or was otherwise rebooted
                logger.debug("CoAP POST returned 404, our session is gone.")
                await self.coap_ctx.shutdown()
                self.coap_ctx = None
            elif response.code != Code.CHANGED:
                logger.warning(f"CoAP POST returned unexpected code {response}")

            return await self._decrypt_response(response)```

i don't know - not a HAOS user myself

#

you can do it with nano if you are somewhere where which hass return a path

#

if you have an ssh that can do docker ps and see the HA container, that would work too

#

and then yeah, we just need to add the 3 lines i marked with +'s

#

(obviously without the +s)

clever sinew
#

So Docker ps works from my SSH shell, but when I ls I don't see a directory for aiohomekit

#

Nevermind it was in /usr/local/lib/python3.11

#

Does it normally break fairly often?

#

Ah you said it was every 5 mins

#

Ok

#

If it’s stable in morning that’s a good sign then

clever sinew
nimble snow
#

Was reading the code and there is a case where the remote device returns a 404 Not Found which means the encryption session is invalid, and we handle that.

#

And we see that when a device restarts

#

So I’m confused about what happens that makes the device not return anything

#

And to all devices..

#

Very weird

#

There is a risk with this fix that it might cause some problems for battery powered devices

#

The underlying library does automatic retries

#

And I don’t know how they interact with the timeout that we are hitting here

#

I think it’s fine, but might have to back it out if any problems crop up in the beta

clever sinew
#

I have AdGuard Home running in an LXC through Proxmox, could DNS routing impact it at all?

nimble snow
#

It shouldn’t do

clever sinew
#

I ask because the internet connection issues I experience feel more like a DNS record taking a long time to finalize as opposed to a straight 404 connection

nimble snow
#

Is HA wired?

#

And what’s your Br?

clever sinew
#

I've got 4 homepods and 2 apple TVs. I can check what the main BR is from HomeKit, right?

nimble snow
#

No

#

The primary hub in the Apple app is something else

#

You know how HA is like a server app ? Apple seem to have made something like that, that runs on the HomePods or AppleTV

#

But we don’t (and can’t) access that

#

We actually use a random BR

#

Are the Apple TVs both wired?

clever sinew
#

One of them is.

#

I just unplugged all of the HomePod Minis and turned woke the wired ATV. Hoping to force that to become the BR

#

Common complaint in HomeKit discussion that we can't select which device is the BR 🙄

nimble snow
#

In terms of BR, all of them are BR at once

#

And when a packet comes from the mesh to your wifi it should come out of the Br nearest that device they sent it

clever sinew
#

Oh okay so I don't need to worry if my non-wired HomePod Mini is showing as the main Home Hub?

nimble snow
#

In theory if all of your BRs have trel it doesn’t matter at all

#

(Look for _trel._udp in an mdns/zeroconf tool)

#

The HomePods should do if firmware up to date

#

I think so for Apple TVs too but slightly less certain

clever sinew
#

Yeah I've got 5 devices in that

nimble snow
#

What I’m interested in is whether your router can mess it up

#

Do you have switches and dedicated WiFi APs or just a combo router

clever sinew
nimble snow
#

Oh

#

Funnily enough my Unifi gateway died recently

#

I’m running openwrt

#

It feels like thread is behaving better with openwrt

#

But time will tell

clever sinew
#

Bought an N100 on a deal yesterday and as soon as it arrives I'll be using it as the router with everything else as dumb APs, so hopefully that helps!

nimble snow
#

Pretty much my setup

clever sinew
#

Already I'm pissed that TP-Link limits you at 64 address reservations

#

Reading the OpenWrt forums it seems like gigabit + homelabbing just requires a full computer as a router. Consumer grade and even entry level enterprise grade hardware is not necessarily built for the level of demand we're pushing

#

Without entering into the thousands of dollars, that is

nimble snow
#

I could saturate my fibre link with the unifi gateway but only if I turned features off

#

Ok if you are replacing the router anyway won’t dig too deep into the root cause just yet

#

But will try and get a PR open with the fix in in the next few hours

clever sinew
#

Yeah let me know if I can help identify battery related issues too. I've got Eve Thread items that are flawless on the network which helps me feel sane when Nanoleaf shits the bed

nimble snow
#

ah nice

#

what Eve devices?

clever sinew
nimble snow
#

ok

#

and the thread devices are on HA already?

clever sinew
#

Yup!

nimble snow
#

ok

#

can you make yours look like that, restart ha, turn on the debug logs, then use the "identify" button on the eve devices and see if it (a) works and (b) check to see if that log message is in there

#

if the identify button works and we don't trigger that new log message we are good to go

clever sinew
nimble snow
#

yeah

#

are the door sensors on homekit still xD

clever sinew
#

No I made that Matter too. How about an Onvis 5-Button Thread switch?

#

Wait, shit that's paired to HomeKit directly, not HASS

#

Damn, I guess I have less devices on thread than I thought

nimble snow
#

Lol

#

The onvis would probably do it if you could temporarily move it

#

I imagine bit of a pain with automations

clever sinew
nimble snow
#

Entering toddler o clock here so you will probably be the one

clever sinew
clever sinew
#

@nimble snow So sorry about the long delay! Would it still be valuable for me to test this?

ALso, if I update my HASS will I need to redo the changes that you suggested?

nimble snow
#

So just hoping battery powered devices still work 😂

#

If you can test that would be great

clever sinew
#

I'm updating now, will do the connection dance with the Onvis button after

nimble snow
#

Yes it does 🙂
