Updated IKEA E2001/E2002 to latest FW and now doesn't respond

[smartroad]

What happened?

I updated my IKEA E2001/E2002 controller over OTA and all seemed to be okay. Now that it has updated, it is no longer responding. It joins fine, but there is nothing when you press a button (action never changes). It also shows the battery as 200%

What did you expect to happen?

No response

How to reproduce it (minimal and precise)

No response

Zigbee2MQTT version

1.38.0

Adapter firmware version

6.10.3.0 build 297

Adapter

SONOFF Universal Zigbee 3.0 USB Dongle Plus ZBDongle E

Setup

Addon Home Assistant

Debug log

No response

I'm having similar issues with the latest firmware on the IKEA E2001/E2002. The buttons don't seem to work, or only long presses are recognized by the device. Reinserting the batteries in the device seems to fix the issue for a couple of days, but the problem always comes back. I have this issue with all of my IKEA E2001/E2002 devices (three of them). I even migrated from a SONOFF ZBDongle-P to an SLZB-06M adapter, but the problem persists on both of these adapters.

Similar comments are reported here also; https://github.com/Koenkk/zigbee2mqtt/issues/22651

[schafran]

Similar for me. Updated the devices to 2.4.11 and the arrow buttons stopped working. On and off buttons still doing fine.

[martintilma]

I'm running: Z2M: 1.39.0 commit: 0326926, HA: 2024.6.4, Firmware: 2.4.11

When the buttons stops working I remove the battery and put them back. Then the buttons start working again. After a day they stop working again. How can I help debugging / fixing?

[Nezz]

I have the same issue. Ever since the firmware update the remote has barely been working. It works after reinserting the battery for a day or two. The issue is still not fixed in 1.39.0. Is it possible to revert the firmware?

I tried pairing again and using the suggested binding, but it still does not work reliably.

For example pressing the right button publishes one of these two variations:

[Bkrickl]

I also have the exact same issue and did not find a solution yet. I am at 1.36.1.

[EricV-hue]

Discussed this also in the forum topic https://github.com/Koenkk/zigbee2mqtt/discussions/23243.

After experiencing the same things as mentioned above I currently use a Trädfri hub and one Styrbar remote + lightbulb, to check the remote. This combination is now already active for at least 2 days without interruption. I now will try to install an older Z2M version as local add-on. See what happens. I will look for a version before 1.36.1.

[DerOetzi]

Have same issue, maybe some kind of "timeout" I have one in my office room works fine the whole week, after 2.5 day no usage over weekend have to reinsert the battery

[EricV-hue]

Quick update: The remote on the Trädfi hub is still working as it should be. My Z2M is now on 1.35.0. The remote connected to HA works fine, key presses are reported correctly, even for multiple days. Until the left arrow key is pressed. The response then gets unpredictable: sometimes i get brightness_move_down, or brightness_stop. Also the long keypress behave inconsistant. i think this behaviour was intended to be solved in 1.36.0? At some point, after pressing the left arrow key a number of times the remote stopped. After a Soft reset (battery remove) the responses were normal.

Does this suggest that it is not the remote control update but the z2m software causing the problem?

[Nezz]

The issue is resolved by a firmware downgrade, you can follow the instructions here: https://github.com/Koenkk/zigbee2mqtt/discussions/23243#discussioncomment-10038494

[EricV-hue]

Although downgrading is working, I think this is more a workaround than a solution. Downgrading the remote does not explain why the same remote combined with a Trådfri hub works without problem.

is there a handy way to do some sort of sniffing on mqtt messages?

[Nezz]

It is indeed a workaround. I believe zigbee traffic sniffing would be needed: https://www.zigbee2mqtt.io/advanced/zigbee/04_sniff_zigbee_traffic.html

IKEA probably introduced something in the new firmware that causes the device to enter a bad state after a day or two. The Tradfri hub might send something to the remote once a day that keeps it in the working state. Or it might set up a reporting that's needed to not brick the remote.

[EricV-hue]

Maybe. But that does not seem to explain why the remote keeps working with z2m 1.35.0. That is, as far as brightness_move_up and brightness_move_down are concerned.

[martintilma]

I played with the Availability setting (from simple to advanced) but I didn't notice any difference. The last days the remotes are working fine again.

[EricV-hue]

Which version of z2m and remote firmare are you using?

[martintilma]

1.39.0 commit: 0326926

Remote firmware: 2.4.11 HA: 2024.7.2

[victorhooi]

I also seem to be hitting this issue, and would love to see it resolved!

My information in case that helps:

Zigbee2Mqtt: 1.39.0 commit: 0326926 Adapter: UZG Gateway (UZG-01), running ZXG firmware (240707), and z-stack 240710 (although I've also tried with 20230507)] IKEA E2002 Styrbar Remote: Firmware 2.4.11

I do note that like others, taking out the battery, and putting it back in seems to make the remote work for about 1 day - but then it suddenly stops working.

I can try looking at Zigbee traffic sniffing, if people think that would help - is https://www.zigbee2mqtt.io/advanced/zigbee/04_sniff_zigbee_traffic.html#_3-sniffing-traffic the best way to start?

I wonder if there's some way of doing it from the Zigstar adpater itself - or is it best to get a secondary Zigbee-capable device/adapter to do the sniffing? And I assume it would need to sniff for more than a 24-hour period?

[Koenkk]

@victorhooi having a sniff from the working situation until the failure will definitely help. Make sure to sniff close to the coordinator. Note that it requires a separate adapter (cannot be done with the coordinator)

[EricV-hue]

Quick update: i now have 2 Styrbar remotes working with no issues for about 1 week. Z2M version 1.35.0, Styrbar 2.4.11

[Koenkk]

Could you check if the issue is fixed with the following external converter (in combination with z2m 1.39.0)

• save this as file next to configuration.yaml as ext_converter.js
• add it to configuration.yaml:

  external_converters:
  - ext_converter.js

• start z2m,
• in the frontend, check if the description of this device now ends with CUSTOM (this indicates the external converter has been loaded correctly)
• check if issue is fixed

[EricV-hue]

Will do that. Updated z2m to 1.39.0 and now waiting for the issue to reoccur (or not?).

[Nezz]

@Koenkk I tried to load the external converter but no luck:

z2m: Failed to load external converter file 'ext_converter.js' (Cannot find module '../lib/develco'
Require stack:
- /app/dist/util/utils.js
- /app/dist/util/settings.js
- /app/index.js)

After removing the unused imports:

z2m: Failed to load external converter file 'ext_converter.js' (Cannot read properties of undefined (reading 'options'))

[Bkrickl]

Will also try it. Had to adjust the code a little bit so it is working for me on 1.36.1.

Commented out the following:

// const {develcoModernExtend} = require('../lib/develco'); // const {battery} = require('../lib/modernExtend'); // if (utils.hasAlreadyProcessedMessage(msg, model)) return;

Since these things are not available for me

Then i added const globalStore = require('zigbee-herdsman-converters/lib/store');

Will come back to you to tell if i have or don't have any issues.

Whoops, updated https://gist.github.com/Koenkk/3d766bc346c74cb985b75cbb13eb7c6e

[Nezz]

I tried the updated one and @Bkrickl's suggestions too, but it's still failing to load with 1.39.0:

z2m: Failed to load external converter file 'ext_converter.js' (Cannot read properties of undefined (reading 'options'))

[Nezz]

I managed to make Z2M load it, here is what worked in the end: https://gist.github.com/Nezz/d036fb0047b667e7c91a13ccd5a4b33c

The issue was not fixed by this right away - I think the remote enters a bugged state after a day or so and it was already in this broken state. I re-inserted the battery to make it work again and will report back in a day or two.

[Maverick5269-lab]

On the ikea thread says a new firmware with fixes are available 2.4.16 but i think is only available for ikea hub.

can someone know the download link manually?

[Nezz]

Looks like they indeed released that update to fix these issues: https://www.reddit.com/r/tradfri/comments/1e4lq3f/styrbar_firmware_version_2416/

Sadly they have not published it here: http://fw.ota.homesmart.ikea.net/feed/version_info.json

I think this new firmware fixes the remote that enters a bugged state after a day or so. Without it I think it will always enters in this state after sometime in standby. From the Ikea thread this happens not only in the home assistant but with Ikea hub too. I assume this is a firmware problem with device and not from Zigbee2Mqtt.

Thanks I didn't knew were they were published. But appears the IKEA Hub goes to other address getting it. From the thread the hub is DIRIGERA that applies the new version.

[Bkrickl]

For me the same issue occurs even with the external converter. So i think i have to wait for the updated to be available for z2m.

Maybe it will work with this update.

[Bkrickl]

Update is now available. I already installed it for some of my devices. All actions seem to work without any issues.

Will come back when tried it multiple days to see if the issue is now resolved

After our holiday 2 out of 3 remotes where working. Happy to see an update available. I will install them too to see if this solves the issue.

[ElBalsero]

I am not able to bind to groups in this version. Was someone luckier?

I had to turn off OTA IKEA test url and reboot, then they showed up for my 5 remotes. I had to press a button on the remote while searching for update, to establish a connection

[Nezz]

I must admit that I pressed "check for updated" many times before realizing that I enabled the OTA IKEA test url out of desperation a couple weeks ago.

I had to turn off OTA IKEA test url and reboot, then they showed up for my 5 remotes. I had to press a button on the remote while searching for update, to establish a connection

Oh, thank you, thank you, thank you! Many, many thanks as I forgot that I had enabled the test url similarly out of desperation just like @Nezz. How long this might have gone on? Possibly forever.... Remotes are updating now!!!!

I am not able to bind to groups in this version. Was someone luckier?

Just upgraded one of my remotes and I have the exact same issue - bindings to individual lights work, but no longer for groups.

I didn't notice any issues with 2.4.11, and everything is still working fine on my other remotes still running that firmware.

I am not sure what binding to groups does, but my switch does control a light group without this setting. At 2.4.16 and without 'Groups' checked, light groups do work. I think was a temporary workaround for something, but I'm not sure.

When you bind a switch to a group (or to a device, for what it matters...) what you do is to set the switch to communicate with that group directly without having to rely the communication through the hub.

This means that if your Zigbe2Mqtt goes down for whatever reason, that switch will continue to work and to control the bound group of lights.

This sounds great - had no idea this was an option. Is there some (better) documentation than what is listed in the Zigbee2MQTT doc? For example, how do you control which buttons and what the buttons do when bound directly to a light or group?

[ElBalsero]

Yeah… I can relate to what you say. Perhaps someone else can link a decent document. What I know comes out of pieces of information here and there.

Basically you can separately bind the clusters belonging to every endpoint of the switch.

There’s not much room for configuration besides that.

Some examples:

If you bind the OnOff cluster, the switch will be directly switching on and off the lights in the group.

If you bind the LevelCtrl cluster, your switch will control the intensity of the lights.

If you bind the Scenes cluster, it’ll control also the color or temperature.

There are other clusters that I have no idea what they do. Also you do not choose what parts of the switch do what. This particular Ikea switch, when bound, controls on/off with single presses of the on/off buttons, intensity with long presses of the same buttons and temperature or color with the arrows. That’s how it’s designed, and the functionality you get also depends on the lights you’re using.

And the last thing I know comes back to the endpoints I was mentioning. You can bind different clusters belonging to every endpoint. So, if you have a double switch with two endpoints, you can choose to bind the on/off of the first to a group and the on/off of the second to another different group. However, if your double switch has only one endpoint (like some of the ones made by Philips), if you use the binding functionality, you can only bind the only existing endpoint to one group and both buttons of the switch would then control the same group… which is a stupid waste. So, if you’re looking for double switches to use for binding, don’t make the same mistake a made and make sure you get one with two endpoints.

Bottom line: you do not have a lot of control, but when you get the right combination and things work, you get a home which continues to work even when your Zigbee2Mqtt server goes down, which is a big plus.

Only you have to be very careful with firmware updates like in this case. If I had updated all my switches without asking here before… all would be gone as this version seems to have broken the binding functionality.

Sorry for the long reply. I hope at least helps a bit.

This is great info, thanks. I use the Styrbars for a couple bedside switches for 2 lamps and a ceiling fan light group. The main switch when you walk into the room is a Rodret, so maybe I will tinker with that for binding directly to the light group. Appreciate the info - today I learned.

I’m trying to connect my styrbar (purchased ~2 weeks ago) to my zigbee network, but I’m not getting anything. I’m worried mine shipped with the broken firmware. I have no intentions of getting the ikea hub to update the remote. Should I just return it? Over 6+ hrs of trying, it’s half connected twice, but HA only received a single battery power update, and the button presses didn’t show in the logs.

Any ideas on what to do? I’m at a loss.

PS: I’ve followed the instructions on the z2m website (press 4x rapidly until red breathing light. Press 10x rapidly if that fails. Also tried removing and replacing batteries/starting over).

Half connected? Did it show up in the z2m devices list?

I've updated STYRBAR (E2001/2002) to 2.4.16 and now it is joined in Z2M but no action to keys press (up, down, left and right). In log there is no MQTT message sent and no error message. If I try to re-configure in Z2M the device the log report this:

[2024-09-03 15:24:54] error: z2m: Failed to configure 'dimmer ale', attempt 1 (Error: Bind 0x4c5bb3fffe20450f/1 genOnOff from '0x00124b001938448b/1' failed (AREQ - ZDO - bindRsp after 10000ms)

Z2M: 1.40 HA: 2024.8.2 Remote Firmware: 2.4.16

Update: magically now there are messages related to keys press. The battery level in Z2M web GUI is shown as red % with no value (and is unknown in HA)

Hey @elle2 , That error message looks like an error when trying to establish a bind the on/off cluster. As discussed a few messages earlier, this version really looks like it’s breaking the binding. So, if you’re trying en bind the Styrbar to a group, chances are that it’s not going to work.
