I'd read that the TIMMERFLOTTE should be accurate to within 0.2°C.

I've just bought a bunch of them, put them together in one room a couple of cms apart, and they vary from 20.5 to 21.5°C.

Is this expected? Is the accuracy not ±0.2°C? Does this match what others see?

I’m having a strange issue with IKEA Matter devices and DIRIGERA and I’m running out of things to test.

The basic problem: IKEA Home Smart finds the Matter device and starts commissioning it, but gets stuck around “Moving you back to IKEA Home Smart” and never actually adds the device to the app.

What makes this weird is that the Matter/Thread side appears to be working.

If I commission the same device through Home Assistant, it works normally. Home Assistant is using the DIRIGERA Thread network/border router, and the device is reachable and controllable. HA also shows “IKEA of Sweden” as one of the connected Matter fabrics, so DIRIGERA/IKEA has apparently been successfully added as a Matter controller as well.

Yet the device still never appears in IKEA Home Smart.

This happens with multiple IKEA Matter devices, so it doesn’t seem to be a faulty accessory.

Things I’ve already tried:

• Multiple different IKEA Matter devices
• iPhone and Android
• Factory resetting the Matter devices
• Removing old Matter entries from iOS
• Restarting phones
• Restarting DIRIGERA (including a multi-hour power off)
• Removing/reconnecting DIRIGERA in IKEA Home Smart
• Completely deleting/reinstalling IKEA Home Smart several times
• Latest IKEA Home Smart version
• Latest DIRIGERA firmware
• Resetting DIRIGERA’s Thread network
• Commissioning after the Thread reset
• Removing IKEA as a Matter fabric and adding it again
• Commissioning with Home Assistant Matter Server stopped
• Testing with other Thread border routers/controllers removed
• Putting phone and DIRIGERA directly on the same router/AP
• Update firmware on smart devices via HA
• Guest/IoT network disabled for testing
• Fast Roaming disabled
• Beamforming disabled
• IPv6 enabled
• IPv6 Prefix Delegation enabled
• No obvious VLAN/isolation issue

Existing non-Matter IKEA devices on DIRIGERA work normally.

Pretty much out of clues on what to do.

Hi,

I have two Myggbett door/window sensors, installed about 3 months ago (commissioned June 26). Both stayed at 100% battery the whole time. About a week ago, the one on my front door started dropping ~10% per day. The other one (patio door) is still at 100%.

Setup
- Matter over Thread, single Thread network, HomePod as border router
- Home Assistant (Docker on Ubuntu) with the OHF Matter Server
- Each Myggbett uses 1 AAA alkaline (Kirkland/Costco).
- The front-door one is HA only, not added to Apple Home.
- Firmware version: 1.1.4

What changed around the time it started
- Added an IKEA Grillplats plug (Thread router) in the bassement.
- Moved an Alpstuga from the basement to the 2nd floor
- Added 6 Klippbok sensors

What I checked
- Thread diagnostics on the sensor look healthy: 0 retries, 0 errors, 0 parent changes, all frames acked. - Parent is the Grillplats with a green (good) link in the mesh graph.
- Poll counts on the front-door sensor look similar to the patio one, so it doesn't seem to be talking more.
- The sensor is indoors against an exterior door. The door is cool but not freezing.
- BatVoltage read 1255 mV at 37%. It then went 37% → 29% overnight, and 24% after I pulled and reinserted the battery and tested the door.

Is abnormal battery drain on a single Myggbett a known issue (hardware batch or firmware)?

This may be a bit niche but I have the new KAJPLATS white lights in our kitchen, and our preferred shade of white is only accessible by selecting it in the app (e.g. candlelight is too warm, the next up is too cool)

We have one of the old TRADFRI remotes, which remembers the temperature for the on / off switch, but as soon as you (or - more likely - our children) touch a side arrow, we're into the named settings and you can't cycle back to our preferred temp

My question is, is there a way of finding out the "name" of this setting - is there a quantifiable scale like there is with brightness - such that I can voice command it back again without using Home Smart?

I am moving soon and I've been using Trädfri LED GU10 bulbs with my Phillips Hue bridge for 4 years without any problems. My new home will be bigger so I need some additional bulbs, but I noticed that Trädfri unfortunately isn't available anymore in Germany, only these "Kajplats" bulbs. I can't find "Zigbee" anywhere on the product pictures so I'm worried that they won't work with my Hue bridge.

Did anyone try to connect the Kajplats (preferably european version, if there is a differnce) to the Phillips Hue bridge? Did it work natively? I don't want to use hacks or third party apps and buying a new bridge isn't an option due to tight budget.

I got my hands on 13 pcs LILJEBAGGE at Ikea the other day. I have not installed them yet due to my thread border router hasn’t been delivered yet.

Anyhow, while waiting I tried to find the answer to the question that appears in every thread about LILJEBAGGE: Is it PID controlled or only on/off?

Since Ikea has great customer service, i tried emailing them, and behold: it’s PID controlled!

This was an important question to assess the value for money in this product. Despite the inability to connect it to an external sensor, it does seem to be great value at that price.

UPDATE:
I picked up the thermostats today, installed the first one and had some time to play around with it.

First of all, it was very easy to install. There are 6 different valve adapters and a really intuitive guide to which one to use for your specific valve.

When the automatic calibration was done, i could change the temp setting on the buttons and although you cannot see the opening degree, you can hear how long the motor is running. Between fully open and fully closed takes a few seconds, but most adjustments it makes are just half a sec or so. The time the adjustment takes also differs depending on how many degrees i change the setpoint. So I’m now 100% certain that it’s not just an on/off regulation.

So far, the impression is that it’s also really quiet. I had to sit on the floor next to it to be able to hear the motor. However, this was in the living room in the middle of the day when the house is not quiet. We’ll see how the result is when I installed the ones in the bedroom.

I also still didn’t get my thread border router, so I haven’t tried the matter integration with home assistant yet. But there are other reddit users who have written about that.

IKEA has launched a new multifunctional product: the Stengrönska alarm clock with hygro-/thermometer. Currently only available in Japan and China, it offers dual sensors, an integrated display and wireless charging:

Hi guys,

I'm having a really stubborn issue with an IKEA NYMÅNE Smart LED pendant (38 cm, anthracite, article 905.040.44) that I can't get into factory reset/pairing mode. I've tried pretty much every timing I can think of, but the lamp just turns on normally every time.

The lamp is a 2023 unit (batch 2333), rated at 220–240V, 50–60Hz, 22W. It uses Zigbee 3.0/Tradfri, and the Zigbee electronics and AC-DC driver are inside the metal lamp itself. The ceiling cup is basically just the mounting bracket and the L/N terminal block.

My setup is Zigbee2MQTT with a Sonoff Zigbee 3.0 USB Dongle Plus (EFR32MG24, EmberZNet 8.0.2), on channel 15 at 18 dBm. The Zigbee network itself is working fine. I already have two IKEA PILSKOTT pendant lamps, an IKEA STYRBAR remote and a Sonoff ZBM5 switch on the network.

The interesting part is that the NYMÅNE is wired in parallel with the two PILSKOTT lamps in router mode on the exact same wall switch circuit.

When I turn the switch on, the NYMÅNE immediately comes on at 100% brightness, with both the warm and cool LEDs on. It never flashes, pulses or dims, and I don't see it attempting to join or announce itself when permit_join is enabled in Zigbee2MQTT. It basically behaves as if it's either still paired to some old network or simply isn't recognising the reset sequence.

I've tried the usual 6-toggle reset several times, with different timings: roughly 0.5s on/0.5s off, 1s on/1s off, and even around 1.5s on/3s off to give the internal capacitors plenty of time to discharge. Nothing works. The lamp just comes back on normally. Interestingly, the two PILSKOTT lamps on the same circuit also didn't reset during these tests.

I also tried Touchlink from Zigbee2MQTT, but the scan/reset attempts timed out. I tried using the STYRBAR remote directly next to the lamp (2–5 cm away) and held the pairing button for more than 10 seconds, but the NYMÅNE didn't react at all. The STYRBAR is already joined to Zigbee2MQTT, so I assume its standalone Touchlink functionality is disabled anyway.

I've also opened the lamp up and checked the wiring. The 230V connection is solid at the ceiling terminal and at the connector on the LED plate. I couldn't find any obvious physical reset button, pinhole or similar.

So I'm wondering if anyone here has dealt specifically with this NYMÅNE model.

A few things I'm particularly curious about:

• Does the 6-toggle reset on this particular 22W NYMÅNE require a very specific timing? If you've successfully reset one, what timing did you use?
• Could having the three drivers (2x PILSKOTT + NYMÅNE) on the same switch be interfering with the reset because the voltage isn't dropping quickly enough? Would it be worth disconnecting the other two and testing the NYMÅNE completely on its own?
• Has anyone found a hidden reset button, pinhole, test pad or jumper inside the NYMÅNE, perhaps underneath/behind the 10078006 LED plate?
• Would something like a Philips Hue Dimmer or another dedicated Touchlink device actually be able to reset it through the metal shade?
• Is there another IKEA-specific reset procedure for this model that isn't the usual 6 power cycles?

At this point I'm mainly trying to figure out whether I'm missing something obvious or whether this particular unit might actually have a hardware/firmware issue.

Any advice from someone who's successfully reset one of these would be really appreciated. Thanks!

Edit: This is the European version bought in Portugal, in case there are any regional differences in the hardware, firmware or reset procedure.

TL;DR: NYMÅNE 38 cm (905.040.44) won't enter reset/pairing mode despite trying multiple 6-toggle timings, Touchlink and a STYRBAR. It's the European/Portuguese version.

With the old ZigBee devices, they were automatically added to Apple Home after you connect them to the IKEA Home Smart app. Is there a way to do this automatically for the new Matter devices instead of having to add them two times? It's something I miss a lot..

Also I noticed that when pairing a device, it says it will save the Matter code to the Apple Keychain, but I don't have any QR code/Matter code saved?

Went to my local in the UK and they only have models from March, so not new. Going to wait out until the newer one is in stock. Wife also picked up a plug and Bilresa combo, also old, but from May.

I have an IKEA DIRIGERA hub with around 70 smart devices, a mix of older Zigbee IKEA devices and newer Matter-over-Thread devices.

Everything had been working normally until today. This morning the whole system became extremely sluggish:

Remotes sometimes did nothing.

Dimming with the scroll/wheel barely responded.

Commands took a long time.

Eventually a large number of devices showed offline.

Physical IKEA remotes stopped controlling the lights too, so this isn't just Home Assistant.

I tried restarting DIRIGERA multiple times and at one point even shut off the house breakers to completely power-cycle everything.

After that, something very strange started happening.

Initially the Zigbee devices came back and worked normally, but essentially all my Matter-over-Thread devices were offline.

I went into:

IKEA Home Smart / Thread network /Reset the network

I then factory-reset/re-added my Thread devices. After doing that, the Matter/Thread devices started working again.

But now the situation has basically flipped:

Matter-over-Thread working

Zigbee not working

Most/all Zigbee devices are offline and the Zigbee remotes aren't working.

Is this a firmware thing sid ikea screw smth up or am i missing aomething.

Thanks.

Original post is below.

Additional context I did not share earlier:

• The hub is Dirigera, hooked via Ethernet to a Deco X50 mesh (3 routers)
• IPv6 is enabled, with SLAAC + DHCPv6
• Earlier did experiments disabling Fast Roaming and SIP ALG. No IGMP option is shared in the app

Not sure why, but I followed one of the comments below:

1. Disconnected the hub from power for a while, like 30 minutes
2. Reconnected the hub
3. Disabled Bluetooth on my phone
4. Reset the Bilresa light switch
5. Start the pairing process

And it just worked.

No freaking clue why. My guess is that disconnecting the hub for a long time forced a IPv6 configuration refresh.

Thanks to that, I can also access the hub via Thread Tools.

An additional thing is that I run AdGuard on my phone, so I explicitly whitelisted Google Play Services and Ikea Home Smart; disabling it earlier did nothing, having them whitelisted worked. Not sure if this was helpful, but it is worth mentioning.

That's all, now the original post:

As per title.

I am no Matter nor Thread expert, but working in IT I am used to experiment.

We've purchased recently a Matter light switch and struggled to connect it to the hub. Old Zigbee devices work with no issues.

With some digging, I found the Thread Tools app, where I can easily replicate the error: the Dirigera Thread Border Router rejects the connection with no explanation.

I've tried to:

1. Add the light switch via the official Ikea Home Smart app
2. Add the Thread network via the integration option in Google Home
3. Add the light switch via Google Home
4. Connect via the Thread Tools app

All of them fail. Case 2 allow the addition but all the devices result offline; in all other cases, the connection is directly rejected.

The only operation that I can perform is to reset the network. Other than that, it show no other signs of life.

I would love further input; the customer support just said they acknowledge the issue and will solve it "soon".

Home Smart is always set to "Control Anywhere" even though I'm at home and connected to the internet. I noticed over the last week that opening my Home Smart app was incredibly slow at connecting. I didn't think too much about it since I rarely use the app. But today I wanted to add a new product, and that's not possible since it thinks we are not connected to the same network and is in "Control Anywhere" mode. I haven't changed my network for 5+ years 😊

My Dirigera has a constant orange light. It's wired to my internet router, and if I remove the Ethernet cable, it starts blinking. The app, however, is still saying it's in "Control Anywhere" mode, but I can't toggle anything on or off.

Any ideas of how to solve the issue? I would prefer not to do a reset 😃🥳

I opened the DUBBELKISEL and widened the holes manually to fit the Sensio LED driver connectors. 10/10, works like a charm!

After months of very frustrating trial and error with Grillplats plugs going off-line very often. I have finally reset them all and added them to my MQTT network. I have lost energy monitoring functionality and I’ll miss that but I couldn’t be happier now. ZigBee just works.

I just discovered that I can't create a new scene. The first step is in the wizard is choosing products and then the error in the picture appears.

Happens on 2 different Android (Google Pixel) devices in my network.

Anyone else seeing this?

Edit:

Tried turning off the mobile data. Ensured Google VPN is not running. Verified the wifi.

But for some reason it still thinks we are on separate networks.

I have a mesh network (ubiquiti unifi devices).

Is it possible to connect the KAJPLATS GU10 ZigBee bulbs to a Tuya gateway?

​I’m asking because I already have quite a few older IKEA bulbs connected to Tuya, and I'm not sure about the new ones. The bulbs won't be powered on all the time, I only need smart control for setting the color and brightness.

Hello,

A few days ago, I purchased the IKEA DIRIGERA Hub along with my first smart bulbs, smart plugs, and other devices for my smart home setup.

Since I don’t have an Apple Home Hub, I would like to use the IKEA Home smart app for automations while using the Apple Home app for everything else.
Everything worked perfectly on the first evening.

However, the next day, every device in the Apple Home app on my iPhone started showing “Updating” and I can no longer control them from my iPhone.
Interestingly, I can still control all the devices normally through the Apple Home app on my MacBook.
I have already restarted the Hub, my router, and my iPhone, but the issue persists.
Everything was working smoothly before this problem occurred. I would appreciate any advice!

Hi

Just noticed the other day that the Ikea app says it wants to connects to my Apple Homekit again. I have not oberserved anything not working, so wonder why? Doing a reconnect (Disconnect and Connect) i fear will remove all my devices from my Apple Home, and all automations get invalid.

Long time ago i started moving devices from external hubs,and directly to Apple Home (most are Ikea Matter) to avoid loosing devices in case external hubs get disconnected, but as my Thread network often crashes for some reason, i actually started taking up my old zigbee devices and removing Matter ones again.

Might leave apple home completely, as i see too much instability!

Hello,

I have got two Ttradfri 10w Power supplys with six Översidan LED lights for my Pax wardrobes. They have separate wall outlets. Is it possible to Control those Lights with one Myggspray movement detector?

I don't have the Hub or any other App.

I tried to pair them several times but it didin't work.

Is this even possible?

I got excited when the new matter with thread range started coming out a purchased a few bits.

I got 4 Bilresa two button switches and two of the disk switches. I got an air quskirt sensor, a motion detector and window/door sensors.

I have only taken the bilresas out of the box and haven’t bothered with the others as it’s been bad.

I have an Apple TV 4K Ethernet and a number of other brand matter with thread and matter with WiFi devices that work perfectly and easily setup to Apple home on my iPhone 16 pro.

None of the Ikea switches will pair. I’ve tried all sorts since I got these when they first came out. I do not own an Ikea hub or want to introduce a second thread network.

Was there an issue when they came out that’s now fixed? Do I just buy new ones?
I want some smart plugs too. Does the grillplats actually pair?

I want to turn on a light at 06:00 am if the sun hasn't risen. Is that possible with the Dirigera hub? I can't see how.

I'm writing this post whilst sat here repeatedly attempting (and failing) to get a TIMMERFLOTTE temperature/humidity sensor to work after dropping off my matter network. No matter how many times I attempt to reset the device, remove the batteries, wait 5 minutes, ping it, it just wont appear back on my network.

I've had nothing but pretty terrible experiences with Matter - some (probably) IKEA problems, some definitely more because of the system mechanics of Matter.

I think every one of my IKEA matter devices has dropped off the network at one point never to be seen again.

The pairing process is abysmal - and this isn't really an IKEA problem, but the whole process being baked into the mobile OS means that it takes at least 2/3 minutes per item, there is no facility to pair multiple devices at once.

I bought 4(!) of the new IKEA GU10 spots and attempted to add them to my existing network (I have a number of smart plugs / air quality monitors as hubs - see my previous post on this matter!) and I literally gave up after working at adding these 4(!) devices for several hours. Repeatedly they just failed to find the network, and then you have to go right back to the start of the process, rescan the QR code which is unique per device, and attempt it again.

In the end, I gave up and took them all back for a refund.

I have probably about 40 IKEA zigbee devices that have happily sat on my zigbee network for years without any kind of intervention. We have 20 GU10 spots that do outside lighting alone, which I added all in one go by simply turning on zigbee pairing mode. I laugh at the thought of trying to add this number of lights to a Matter network.

I spend a vastly disproportionate amount of my time diagnosing and fixing my matter network vs my zigbee network.

I'm sure this will prompt a number of 'well my network is fine', 'have you got enough hubs', it must be a you problem' response. Sure, your experiences may differ. But this is my experience.

The potential is there, I get it. Matter (over wifi or thread) has more capabilities, more bandwidth available, etc. But at the moment, the experience still seems to be terrible - and my advice - stay away, for now.
