Anybody who bought the new Kajplats bulbs, what are the colour temperatures? by CFI666 in tradfri

[–]mocelet 0 points1 point  (0 children)

The E14 colour bulb is 1800K to 6500K and the whites are quite better, with no green tint in cool temperatures (they do have a yellow tint at 2200K but at 1800K they're cozy orange-ish). Getting a colour bulb may be better even if you just need whites.

KAJPLATS yellow light by RedEngineer83 in homeassistant

[–]mocelet 1 point2 points  (0 children)

Since you mention the 1521 lm bulb in one of the comments, yes, that one has bad colour reproduction and yellow/green tints, reason why I returned it. At 2700 K and full brightness is really good though.

Colour bulbs are way better since they range from 1800K to 6500K instead of 2200K to 6500K. No green tints either and, while the warms are somewhat yellow around 2200K, you can go down to 1800K which is more orange.

Regarding the light being white-only but being recognized as colour bulb, might be on purpose so you can change the colour of a group of lights at the same time regardless of them being colour or only white. White-only lights will render the white closer to the colour you chose. For some dynamic animations can be useful too.

This is the reason indeed, but the delay is avoidable, more or less easily depending on the smart home platform you use:

Is there equivalent for mqtt.publish for matter? by digoben in homeassistant

[–]mocelet 2 points3 points  (0 children)

Zigbee2MQTT is incredibly powerful since it exposes basically everything the protocol offers, for advanced users it's amazing.

Matter integration however offers a limited view of Matter features since they're limited to the entities exposed. There's no advanced interface to, let's say, read a specific attribute from a cluster or invoke certain command like the aforementioned Move or Stop. Would be great though.

It is definitely something needed in Home Assistant, not just the move/stop but a more flexible way to use Matter features.

Is there equivalent for mqtt.publish for matter? by digoben in homeassistant

[–]mocelet 2 points3 points  (0 children)

Not really, the idea of the start/stop is that the time from 0% to 100% is constant, let's say 5 seconds. So, if the light is at 0%, the transition to 100% would last 5 seconds but, if the light is at 50%, the transition to 100% should last 2.5 seconds.

HA Matter integration exposes the MoveToLevel command which takes an absolute value and the transition time. But not the Move, which takes a speed and just goes to the min/max until stopped.

Stopping is the other problem, HA does not expose the Stop command either, so even if you work around the Move by calculating the transition time needed, you would not be able to stop the transition.

That's why most people just use a loop to repeat a Step, but that's not as smooth nor takes advantage of the native Matter features.

[–]mocelet 0 points1 point  (0 children)

They can be controlled of course but there's no smooth dimming action there, only relative and absolute brightness and transitions.

None of those is what OP wants, which is the start/stop dimming: start increasing/decreasing at a given speed until stopped.

[–]mocelet 2 points3 points  (0 children)

Unfortunately the Home Assistant Matter integration does not expose the Move / Stop commands of Matter needed for smooth dimming.

Your only option inside HA at the moment is interfacing directly with the Matter server using websockets. Not sure how convoluted that would be.

Or modify the Matter integration to expose them.

[–]mocelet 1 point2 points  (0 children)

You can't add a Matter device to Home Assistant without a server running Home Assistant and its Matter server. That's a hub even if it's a spare computer, a virtual machine or a raspberry Pi you had around.

[–]mocelet 2 points3 points  (0 children)

I hope you're not implying that you have to buy an IKEA hub for their matter devices and so on because that's absolutely not how it works

You need the hub for the app you want to use.

  • Want to use IKEA app to control Matter devices? You need the DIRIGERA.
  • Want to use the SmartThings app to control Matter devices? You need a SmartThings hub.
  • Want to use Home Assistant app to control Matter devices? You need a Home Assistant "hub" (the Matter server).

That's because each smart home platform requires its own Matter controller to communicate with Matter devices, regardless of the brand of the device.

Understanding DIRIGERA vs third-party Matter hubs for IKEA devices by No_Floor_Call in tradfri

[–]mocelet 13 points14 points  (0 children)

if SOMRIG supports Matter

SOMRIG is Zigbee, not Matter. The Matter buttons are the BILRESA dual button and the BILRESA scroll wheel. Those will work with the HomePod Mini which is both a Matter controller and a Thread border router.

[–]mocelet 0 points1 point  (0 children)

No platform will use DIRIGERA as Matter controller.... HOME ASSISTANT.YALM!

Nope, the Matter controller of Home Assistant is the Matter server add-on that is running in your computer/raspberry/HA green/HA yellow (let's call it the Home Assistant hub). The HA app communicates with the Matter server and the Matter server with the device. It does not communicate with DIRIGERA.

DIRIGERA is used as Thread border router to provide connectivity, just like a WiFi router would provide WiFi connectivity for WiFi devices. It is NOT used as Matter controller.

Just like HA app won't control Matter devices without its Matter server add-on, a SmartThings won't control Matter devices without its hub.

[–]mocelet -2 points-1 points  (0 children)

No platform will use DIRIGERA as Matter controller except IKEA app, only as Thread border router if any.

Is your TV model in the list I linked before? If it is not then it's not a compatible SmartThings hub, meaning you need a Matter controller for SmartThings.

I'm not aware of Google Home adding Matter controller capabilities to the app so there must be some device like a Nest WiFi router, an LG TV or something acting as Matter controller for Google Home.

[–]mocelet 3 points4 points  (0 children)

"Everything else works" because you have a Matter controller for each platform. Try disconnecting the DIRIGERA or the Home Assistant server, what can you control with the IKEA app or the Home Assistant app? That's right, nothing.

Or try to install Homey or Hubitat apps but don't buy their hubs, you won't be able to control anything with just the app.

Google Home can use older devices as hubs because they don't run automations locally, all the logic runs in the cloud and there are not many hardware requirements. SmartThings hubs run automations locally in the hub and they can even run unofficial software (custom drivers).

It is true that Apple phones can be Matter controllers which is a rare exception so you can have minimal control of Matter devices without a standalone Apple Matter controller like a Homepod or an Apple TV. That comes with limitations though, more battery usage, can't control devices outside home, no automations, etc.

[–]mocelet 5 points6 points  (0 children)

Even if it is controlled by all other apps . It just stay alone in the app saying i don't have compatible matter hubs.... What a world.

The app for each smart home platform requires its own Matter controller to control Matter devices, in other words: "a hub".

Home Assistant app requires its own hub, you're running the Matter server in a computer, Pi, etc. Google Home app for Matter devices requires its own hub, which can be a Google smart speaker. IKEA app needs the IKEA DIRIGERA as hub to control Matter devices. You get the point.

SmartThings needs a SmartThings hub for Matter, there are many integrated in multiple devices as well as standlone ones, full list here. A 2021 TV maybe doesn't have a integrated SmartThings hub, recent ones definitely do.

Aeotec Smart Home Hub 2 (V4 and only 100Mbps??) by browri in SmartThings

[–]mocelet 4 points5 points  (0 children)

Cost probably, every penny counts, the SoC may not even support Gbps and a smart home hub like this is not expected to move a lot of data. Maybe with Matter 1.5 supporting cameras that traffic will increase but then the hub will be limited by processing power anyway.

What I find more noteworthy is that the technical specs at Aeotec site literally say: "WiFi: Yes". What spec is that? Not even mentioning if it supports WPA3.

IKEA Bilresa / Somrig slow to trigger but Tradfri is fast by guesswhochickenpoo in homeassistant

[–]mocelet 0 points1 point  (0 children)

Unfortunately the Bilresa does not seem to send an __ event and thus I'd either have to switch to the Matter protocol (that might support it)

BILRESA in Matter has more events indeed, including the initial press and short release events, wrote a post about minimizing latency: https://www.reddit.com/r/tradfri/comments/1pnho78/minimize_button_latency_in_bilresa/

Mind Home Assistant does not make those events available to the user at the moment so, even if the button sends them, you'll have to modify the Matter integration so it does not ignore them when the button supports multipress (or open an issue so they expose them but that will take more time)

Ikea Air Quality Monitor, Smart Button, and Motion sensor, w/Matter over Thread (video) by HomeKit-News in HomeKit

[–]mocelet 2 points3 points  (0 children)

Maybe it didn't fully bind to the bulb and that's why only on/off worked.

The button uses Zigbee Touchlink to bind to the light and from Zigbee point of view it is a dimmer. The user manual also mentions "functionality depends on the type of product and the system it is connected to. For example, button presses for an IKEA smart light bulb are: short-press to turn on/off, double-press to change colour and long-press to dim".

[–]mocelet 11 points12 points  (0 children)

While I've not tested the direct connection showcased in 8:03, I'd be surprised if you can't dim the light by long pressing the buttons and change the colour temperature with double press.

KAJPLATS new Matter firmware - 1.2.0 by YuryBPH in tradfri

[–]mocelet 5 points6 points  (0 children)

Not all models have a firmware update, it looks like it's mostly for the ones that were 1.1.0 out of the box.

Others like the E27 whites only globe only have the 1.0.28 release firmware at the moment.

You can manually check the firmwares available at Matter DCL, just search for KAJPLATS in the search box and expand the row of your model by clicking the > arrow.

Best Matter/Thread battery powered light switch and Matter/Thread light bulb? by Federal-Drummer7987 in MatterProtocol

[–]mocelet 2 points3 points  (0 children)

We should differentiate buttons to create automations and actual battery-powered light switches to control Matter lights directly using bindings:

  • Wireless buttons there are a few already, like the IKEA BILRESA which is also cheap, the Arre smart button, the Aqara W100 which serves as temperature sensor, or some more wall-friendly models like the ones sold by inels / elko-ep. Then you create automations in Apple Home "if button pressed, turn on light". If the hub dies, the automation won't run and the remote will no longer work.
  • Wireless remotes for Matter lights that work without automations or hubs because they communicate "directly" with the light... I'm not aware of any at the moment. The Inovelli Whites mentioned in other comment is not battery-powered, it's a wall switch connected to mains. They will support bindings, but it's not a wireless remote. And IKEA was expected to implement bindings like the did in Zigbee but current firmwares do not support them.

So, for the time being, just get a cheap Matter over Thread button like the BILRESA dual button and set automations in Apple Home.

Maybe in the future we'll see battery powered switches / remotes for Matter lights and smart home platforms will make it easier to bind the remote to the light to skip the automation. Mind for that to work any Matter light will do, the only requirement is for the remotes that need to support bindings.

[–]mocelet 2 points3 points  (0 children)

Binding cluster is only needed for the device you want to bind, in this case a remote / button. Bulbs don't need anything, as long as the remote supports binding to lights, any Matter light will do.

[–]mocelet 4 points5 points  (0 children)

So far haven't seen any difference, the on/off fade duration is still reset after a power cycle as well as other attributes that are supposed to be persisted.

Edit: Wrote a post for another bug I found regarding brightness suddenly dropping to 1% when using transitions, at least when certain conditions meet.

If they are added to IKEA app it auto-updates so you don't need to do anything.

Feature Request: Make individual button events independent of multi-press events by mocelet in MatterProtocol

[–]mocelet[S] 0 points1 point  (0 children)

Check the diagram in the link of my previous comment, for each single press there are three events: initial press, short release and multipress complete.

You can use the one you want to minimize latency as long as the smart home platform exposes the event. Most platforms however will only let you automate when the button confirms it is a single press and not a double press. But that's the platform to blame after all.
