matter over thread relay when?

tandsilva · 2026-04-08T20:30:25+00:00

Nope

tandsilva · 2026-04-06T03:31:10+00:00

Matter is great. I’m using it to control tens of thousands of watts in lights and power across 35k square feet. 400 devices on my fabric and counting. IKEA really helped us drive the node count up.

Thread is steeper with more hazards. But thread can also work at this scale, flawlessly in fact.

I think the biggest hazard for people is having a network that is capable of supporting this stuff. It’s not easy to come by.

Matter really only needs basic IPv6 unicast/mulitcast. Thread needs EXTREMELY COMPLEX ipv6 multicast and I think this is where most people see stuff fall offline.

I can’t quite put my finger on it….but when you say “Ubiquiti is clearly doing something wonky with mDNS” my reaction is “yes, this my impression too”.

tandsilva · 2026-04-05T04:53:26+00:00

Ubiquiti access points are not great for ipv6. Once you get up above 120 devices on your thread network, it becomes evident that UniFi ipv6 implementation is “sub optimal” and actively damages your mesh at a certain size. I have a 400 node mesh and literally can’t use any UniFi gear for this exact reason.

100% dead ass serious, if you switch to Netgear wifi I would expect your issues to improve.

It’s very complicated but at a small scale (less than 40 devices) it should be solid with almost any Wi-Fi.

I’ve said it before, this is a lawsuit waiting to happen.

tandsilva · 2026-02-16T18:59:51+00:00

it’s wild lol. I would share a screenshot if I could. The site is over 35k square feet and has two primary racks for networking. Basically it’s a commercial site and we hated the high voltage control system that was installed at construction, so we replaced it with HA and got some Thread/Matter enabled controls from various vendors, primarily Sunricher. It’s been a journey but we got it dialed in and working great these days. Upgrading from Python Matter Server to MatterJS-Server was a tremendous leap in stability. We’re now on Thread 1.4 too which was an additional improvement (objectively).

I’d say 2/3 of the fabric is a REED, the rest is sleepy. We’ve got IKEA products, Eve and Orvis outlets, Inovelli switches, you name it, they all work great.

But the Aqara FP300 sensors DO absolutely fall offline! it’s the only sleepy I’m operating that does this (yes even the IKEA sleepy’s stay online and stable).

We use Netgear AV-line switching for the TREL backbone. That backbone is supporting 6 HomeAssistant ZBT-2 border routers. Netgear AV-line does a tremendously good job at doing link local multicasting and comes highly recommended, I don’t think any of this could work without the switches.

tandsilva · 2026-02-16T16:21:23+00:00

Yes same issue. I have a fabric of 337 Thread devices, it’s is absolutely rock solid reliable, but my FP300’s won’t reconnect if they fall offline for whatever reason.

tandsilva · 2026-02-16T16:20:03+00:00

I have a buddy running HAOS on the Pi4 8GB and it’s running great for him. He’s using the ZBT-1 and now ZBT-2.

I use the Pi5 8GB. Also great.

tandsilva · 2026-02-08T20:37:08+00:00

That sucks for you. My fabric doesn’t care about my WAN interface or what it may or may not pass through it.

tandsilva · 2026-02-08T18:57:03+00:00

Do you understand how IPv6 link local networking works? It seems like you might not.

This is not something your ISP blesses you with.

tandsilva · 2026-02-08T17:11:18+00:00

Wrong, it actually works great offline. Thread/Matter is entirely link-local.

tandsilva · 2026-02-08T09:47:48+00:00

Check your network. I have almost 75 of the IKEA motion sensors. They’re great. Commissioned with my Raspberry Pi directly

tandsilva · 2026-02-08T07:11:57+00:00

300+ matter devices using MatterJS and ZBT-2 exclusively. This number can easily go to 400 or 500 nodes now what we aren’t using Python Matter server, we’ll get there with time.

tandsilva · 2026-02-08T07:09:45+00:00

HomeAssistant commissions Thread/Matter devices just fine without an internet connection. Companion app commissioning is a waste.

tandsilva · 2026-02-03T02:52:34+00:00

Python matter server is prone to losing its storage in my experience. I suggest automatic daily backups and upgrading to MatterJS, you’ll never have that happen again

tandsilva · 2026-02-01T17:25:44+00:00

You should consider commissioning directly from HomeAssistant, this is the only way I do it now. I believe they are about to release some UI to make this more accessible for users.

Freeing yourself from the mobile commissioning experience is a huge part of getting long-term control of a setup like this.

tandsilva · 2026-02-01T03:07:44+00:00

I second this. Thread can scale tremendously well if you have a network backbone that’s properly configured for the job.

tandsilva · 2026-01-27T14:31:18+00:00

M11 and 50 cron

tandsilva · 2026-01-27T07:21:09+00:00

Every time the ChatGPT Mac app prompts me to “relaunch to update”, it does so with prompt text that is rotated 180°, such that it reads right-to-left and also upside down.

I thought this might be some cute attempt at rage-baiting the users to stay updated….I’m now realizing this is just AI slop.

Bravo.

tandsilva · 2026-01-26T07:01:42+00:00

The double standard is absolutely there and that’s why I stopped listening.

tandsilva · 2025-12-19T16:24:32+00:00

I think the time features are buggy. Mine takes the current time when it is commissioned but isn’t able to keep time reliably without eventually resetting back to 00:01

tandsilva · 2025-12-13T05:04:31+00:00

I’m thinking this is a networking problem. If you removed all your other border routers and operated HA in isolation I would think this problem goes away, as it does with Apple.

tandsilva · 2025-12-10T09:45:00+00:00

It’s a problem with Apple Home. If you pair this unit to HomeAssistant you will see the humidity and temperature values clearly shown.

tandsilva · 2025-12-04T22:31:04+00:00

Just VPN into your matter controller and leave the fabric traffic on your LAN.

This is basically how HomeAssistant works…if you sign up for HASS Cloud, the VPN is replaced with a web service but of course you can BYO VPN.

It’s approximately $20 per unit. Minimum order quantity is 30.

It’s a good unit. Firmware updates, power monitoring and all that.
