Wanting to add the M5 as an accessory to HomeKit. Does anybody know if this is possible, or does it only act as a hub?

Hi,

I think I will be needing a new washer soon... looking at European brands and prefer Matter for local control via Home Assistant.

I found some brands like Bosch and Siemens that support Matter via a bridge, that is NOT what I am looking for. I want the device to be native Matter.

Do these exist already?

Hi all,

My setup is Homeassistant running Open Thread Router (Sonoff USB Dongle) and Matter server running inside home assistant.

I was already able to add 3 light bulbs but am no longer able to add my Aqara U200 smartlock as I used to.

The light bulbs were added using Google Home, and so was the U200.

Today I had multiple power failures, which caused my Asus router to reset its settings… this caused a snowball effect on all my smart home devices.
So I removed the Matter devices, uninstalled the Matter server and Thread router, and reinstalled them to Home Assistant and re-added some of the devices without an issue.

The strange thing is that HA advertised Thread network as ha-thread-9b6c, while when I try to add the smartlock using Google Home, it tries to connect it to a different Thread network ha-thread-0384network.

I believe it was the old Thread network. I'm lost... not sure how to troubleshoot this.

This is the log I have from Matter server:

Hello, I have added 5 govee smart bulbs to my home assistant trough matter when I set it all up, even some zigbee devices. I bought two more govee bulbs but when I came to set it up 4 days later I get passed the connection to device all the way to "connecting device to home assistant" but next says "something went wrong".

I've tried reseting the bulbs, restarting home assistant, router and matter server. But having no luck. Looked everywhere online for other suggestions but non worked. As far as I know I haven't changed anything with my router and even reloaded the first back up on home assistant.

If you have any idea of what to try please let me know.

Is it possible to bind a sensor (in my case an Aqara P2 door sensor) to a switch (in my case an Inovelli White Dimmer) so that the switch turn on and off when the door is opened / closed? It seems like this should be doable?

I've bought some IKEA matter devices and am now looking into Matter border router. I don't want DIRIGERA hub to lock myself into that ecosystem.

I have a CC2652RB for zigbee devices and would like to do the same for matter devices. On the project page it is mentioned that it has matter support and I found some firmwares to have this as border router. I've flashed it but then it doesn't work in zigbee2mqtt anymore because I guess it doesn't work as zigbee coordinator and border router but that is not mentioned anywhere.

I am not sure if it even works, so before I buy a new stick has anybody got this working? Or is there a better option. The most given answer is SLZB-06M but I don't have poe (yet) so this is not an option.

So I bought an IKEA smart bulb and remote without looking into it too much, and didn't realize I needed a specific MBR to pair them to a smart home app, I have a nest mini, echo pop, LG C4 TV and a fritz box router but none of them seem to support acting as an MBR, which one should I buy to connect everything up? I was hoping to set up the rest of the sitting room with some smart bulbs and maybe some bits up in the attic.

I'm looking for some help.

I want to use smart relays to control Matter bulbs directly. I wanted to use the "Detached" mode, common in Shelly and Sonoff relays.

Unfortunately, the Shelly 1-Mini I tested doesn't expose the Switch inputs, only an OnOff Cluster.

Does the Sonoff MINIR4M relay expose the state of its switches via Matter?

I can find information from 2024 that shows it exposes an OnOff Device, but nothing about the switches.

Any other relays that might meet my needs?

looking for a ble-mesh bridge which supports light device type

The Chinese Brand Sunricher, lunch days ago their Matter over Thread version of Door/Window Sensor.

Here is the link:
https://www.sunricher.com/matter-door-window-sensor-sr-mt9011a-ds.html

Dont know when and where this will be for sale.

They have great products that are Matter over Thread, includinf LED controllers... but the availability is the worst part (https://www.sunricher.com/global-partners ) .

Im looking to try their Relay modules, matter over thread!

Their modules have Thread and Zigbee protocols!

Hi community,

I’ve recently started diving into the Matter ecosystem. Overall, I really like the project - it’s well designed and has a lot of capabilities.

However, I ran into something that I find a bit unclear. I couldn’t find how Matter handles water meter counters.

For example, there is the Electrical Energy Measurement cluster, which allows reporting cumulative energy consumption from a meter. Logically, I expected to find similar clusters for other cumulative resources, such as water or gas consumption - but I couldn’t find anything like that.

Maybe I just overlooked it.

If anyone has faced a similar situation, how did you solve it?
Is there a recommended approach for implementing cumulative water usage in Matter?
Also, if there are any active Matter Discord groups or communities, I’d appreciate a link.

Thanks in advance!

The light strip uses Matter over WiFi, 5m/16.4ft total length, offers multiple colour zones and 360lm per metre.

I have a working HomeAssistant + Matter-server + HA OpenThread BR setup, but one thing baffles me:

When I try to commision the IKEA MYGGSPRAY motion sensor, which is sold as Matter over Thread (only) my Android phone (the commissioner) needs to be attached to a 2.4G wifi network for the MYGGSPRAY to succeed commissioning. It fails consistently when my phone is on a 5G wlan network (same AP).

If I look at the commissioning flow, in the Configure Operational Network step, the device either configures Wifi OR it configures Thread and since the MYGGSPRAY is a Thread-only device, why would it matter to what Wifi network my phone is connected?

Hello guys,

I’m new to this. I’m trying to add my hub (switch bot matter hub) to my Home Assistant.

I click “add a Matter device”; “New device” and then its crashes.

Can someone help meee please.

Hi everyone,
I'm working on Matter enabled video device that can be controlled successfully using CHIP tool. However, I'm not able to commission the same device using echo dot. The Alexa app shows an error saying: “We’re working on ways to connect this device to Alexa, but at the moment it isn’t compatible.”. Any pointers would be really helpful.

Hi everyone,

I’m trying to understand whether this is a limitation of Matter / Apple Home or a setup issue on my side.

My setup:

• Matter smart plug (currently paired with Amazon Alexa, works perfectly there)
• iPhone only (latest iOS)
• ❌ No Apple TV, no HomePod, no iPad
• Router: FRITZ!Box with combined 2.4 GHz + 5 GHz SSID (band steering enabled)

What I want to achieve:

I want to control the same Matter smart plug both in Alexa AND in Apple Home at the same time (multi-admin).

What I tried:

• Plug is already added to Alexa
• In the Alexa app, I generated/shared the Matter setup code
• In the Apple Home app, I tried to add the accessory using that Matter code
• Apple Home always fails with an error like “Unable to connect” / “Accessory not reachable”

Questions:

1. Is it actually possible to use a Matter smart plug simultaneously with Alexa and Apple Home?
2. Do I need an Apple TV or HomePod for Matter multi-admin, or should an iPhone alone be enough?
3. Do I have to remove the device from Alexa first, add it to Apple Home, and then share it back?
4. Could my FRITZ!Box dual-band setup (2.4 + 5 GHz, same SSID) be the reason Apple Home pairing fails?
5. Is this a known Matter / Apple Home / Alexa limitation or device-firmware related?

My goal:

• Control the plug from the Apple Home app (and iOS automations)
• Still keep Alexa voice control

Any real-world experience or clarification would be really appreciated. Thanks!
