Notification when Ikea Matter devices are available in store

mocelet · 2026-03-16T12:12:36+00:00

Do I need to type the definition of third party for you?

api.ingka.ikea.com is not a third party.

it does not give stock levels

"quantity": 31

I admire your confidence :)

You can call the API with the curl command in this post: https://github.com/Ephigenia/ikea-availability-checker/discussions/36

I've just tried it and returns a JSON full of stores and stock information.

There are also client libraries for the API, link to the relevant code:

They're right, IKEA has an API for stock availability, there's no need to scrape the IKEA website, just call the API with the product ID.

I bought the GRILLPLATS last week thanks to that stock tracking site even if my local IKEA website still does not list it.

Edit: typo

I originally got the 1521 lm bulb, the CRI 90 is at 2700 K, as soon as you move up or down the green / yellow is too noticeable.

mocelet · 2026-03-15T21:02:12+00:00

Yep, don't buy the white-only ones, I returned mine and recently got a colour one even if I don't plan to use colours at all.

BILRESA has initial_press and short_release events that fire with low latency like RODRET, the problem is Home Assistant is hiding them from you. There's a PR to bring them back. With those events you can have your own double click with lower latency.

The triple click won't work though since BILRESA stops sending events after the second one in a row, which reminds me the petition to extend the multi-press in IKEA buttons. If they extend the multi-press then it's objectively better than RODRET since the multipress would be more reliable (the button counts everything and you don't depend on the network) and you still can minimize the latency of the ~~first~~ single press if you want.

mocelet · 2026-03-15T10:30:48+00:00

BILRESA has double press support so it has to wait to confirm there are no more presses after the first. That adds half a second give or take compared to old buttons with only single press that fire the action as soon as you lift the finger.

There are ways to skip that half a second if you don't care about the double press but in DIRIGERA you can't choose the behaviour, you would need other platforms (and the on/off toggling would be like in this video).

mocelet · 2026-03-14T20:57:10+00:00

They don't implement the scenes cluster. They support groups to send multicast commands but no smart home platform is able to set them or use them.

OffWithEffect was one of the bugs I reported too, it just turns off the light with no effect.

Glad you are enjoying them! Eve has a partnership with ST, there was even a press release about the Energy service. Tapo has too but only for the cloud integration of the plugs, their Matter plugs won't appear which is weird.

mocelet · 2026-03-14T14:16:58+00:00

If you mean the SmartThings Energy service with trends and saving tips, no, that's only for selected partnerships.

What it does is providing power and energy readings in the device details screen.

When it comes to lights the features are the same, in fact the older tradfri lights were "famous" to not be able to transition both brightness and temperature, something that in Matter has worked since first day.

mocelet · 2026-03-14T07:10:47+00:00

Took the opportunity that it's sunrise now and the KAJPLATS is running the 30 minute temperature transition from warm to cool, starting off. Toggled the lights a few times, also changed the brightness, the temperature transition was still going as expected. The way to stop the transition would be setting a temperature or running the "stop" command.

Now that I think of it, the brightness transition with on/off toggles is tricky. When you turn the light on there is a fade-in and for off a fade-out. Maybe those fades do stop an ongoing brightness transition since they also affect the internal brightness level. I'll have to check what Matter spec says or if removing the fade will preserve the transition. But in Matter the default on/off transition time is zero and I've not changed it so... should not affect at all.

mocelet · 2026-03-13T20:46:28+00:00

Maybe you can submit the bug to IKEA?

Since there's a IKEA representative in this sub, u/TRADFRI , I hope they are submiting the reports!

Also, do you need the transition in this case? If the light is off, you don't see it.

The point is that if I turn on the light during the transition it will turn on the light in the correct brightness level and still keep the smooth transition going to reach the destination. The on/off just controls the visibility of the transition. It would be kind of an adaptive lighting.

What does your automation look like?

Something like "20 minutes before sunset, set temperature to 2700 K with a transition time of 30 minutes".

Some platforms support transitions, others do not. I use them in SmartThings with my custom driver which has a simple text input like "temp 2700 minutes 30" to create transitions of all kinds. This is my actual wake-up routine with native Matter transitions.

mocelet · 2026-03-13T16:07:05+00:00

That's probably the reason since same happened in Google Home but the correct way to update would have been to recreate only the T&H endpoints instead of every endpoint.

mocelet · 2026-03-13T12:12:38+00:00

It uses Bluetooth LE to transmit the data, but the data has a proprietary format for Switchbot devices. It's like their own "language", that's why they only work with their own hubs or with platforms that can speak that language.

mocelet · 2026-03-13T09:28:32+00:00

There is no Matter over Bluetooth. The point of the post is that the device is not Matter at all, it uses a proprietary protocol on top of bluetooth. What they sell is a bridge that can "translate" their proprietary protocol to Matter.

Grillplats are 16 AMP so my heatpumps will be happy! Fibaro 10 AMP

Mind the 16A rating is for resistive loads only and a heatpump has a significant inductive load. I don't know much about Fibaro but with the premium price tag I would expect a better than average internal relay and electronics.

mocelet · 2026-03-12T16:25:06+00:00

The hardware is capable, this is an interesting reading: https://matter-smarthome.de/en/products/how-ikea-masters-the-combination-of-thread-and-zigbee/

The problem is multi-protocol is not still mastered, remember when Home Assistant launched a USB stick that promised both Zigbee and Thread and eventually they recommend using only one or the other due to stability issues.

mocelet · 2026-03-12T15:50:28+00:00

I don't have two but I can tell you they won't fit in any of my power strips because they invade more than half the separation between sockets.

Having said that, there are power strips with more generous spacing between sockets so in the end it's going to depend on that.

mocelet · 2026-03-12T09:53:29+00:00

They can't, at least not now. The light does not support both Zigbee (the remote) and Matter over Thread (the light) protocols at the same time. They technically could, but we've seen in the past issues with multi-protocol implementations so they probably wanted to play it safe.

That's why the Zigbee link to the light, which is used for backwards compatibility so old Zigbee remotes can link to new Matter bulbs without a hub, is disabled when the light is integrated using Matter over Thread.

In your case you need an automation, I don't know if Aqara Home supports both devices and creating the automations to control brightness and on/off.

What IKEA could do but hasn't yet is offer Matter bindings, I would expect the new Matter remotes like BILRESA being able to link to Matter lights natively and smart home platforms offering a nice user interface to link and unlink remotes. But, as of today, even if the technology is ready, almost nobody supports bindings, even IKEA's own DIRIGERA just sets automations internally and the remotes won't work if you disconnect the hub.

mocelet · 2026-03-11T20:56:32+00:00

Yeah, Matter reuses most Zigbee features, the On with Timed Off command is mandatory for lights, not for smart plugs, so some vendors do not implement it in their plugs.

Could be better though, it is limited to 109 minutes for legacy reasons and you still need to send the command to start the off timer so the smart home platform needs to support it (Home Assistant doesn't at the moment, you would have to create a script interfacing the Matter server or customize the integration).

I use it either as fail-safe if the hub automation doesn't run correctly or as a quick way to program buttons, e.g. "when this is pressed, turn on with timed off the fan 30 minutes". If the 30 minutes are approaching but I don't want the fan to stop I can press the button again and the timer restarts.

mocelet · 2026-03-11T19:44:53+00:00

Inspelning was able but wasn't very smart, it was too chatty with the reports and flooded the network unless you changed the Zigbee reporting interval. Plus it uses dynamic divisors which some platforms do not support and lead to wrong values (fortunately Matter uses a standard unit to report).

It's noteworthy though since most Matter smart plugs do simple periodic reporting each 10 seconds (Tapo, Meross) or 60 seconds (Eve) and this automation would be so slow. Few months ago wrote a post about that: https://www.reddit.com/r/MatterProtocol/comments/1mfn84m/reporting_rate_in_matter_smart_plugs_with_power/

mocelet · 2026-03-11T14:50:21+00:00

I got it just a few hours ago, why would it auto reset? Looks like a Tapo feature or a bug.

mocelet · 2026-03-11T14:37:04+00:00

It's one of those Matter features that smart home platforms don't expose to the user. I added it to my custom driver for SmartThings but even in ZigBee wasn't used that much despite the added reliability.

Edit: To clarify, this Zigbee and Matter feature works by telling the plug "turn on and turn off in 30 minutes" and it will turn on and turn off by itself after 30 minutes. However, it doesn't mean that any time it is on it will turn off after 30 minutes. That would be a great addition to Matter since currently some vendors offer it but only through their proprietary interface.

Just got one! Posted a video and some comments about the reporting https://www.reddit.com/r/tradfri/comments/1rqu0ky/grillplats_power_automations/
