same here…

I had the same problem. I added a third, and there was no issue, so I removed the problematic button from HA, replaced the battery, held the pairing button on the button for 10sec (I have zero idea whether this resets it or not, but it’s consistent with other IKEA rest procedures), restarted HA, then re-added and it added properly.
I have the same issue, has anyone resolved this?
I did what @deadsquid said but it returns in the same state as OP
My logs are full of zigbee errors, which I can provide if useful to someone
Same issue here 
I even got a shortcut bututon to work. How? No idea - I’ve only read various things that you should initiate an OTA update and then the detection should work better with HA.
Be sure to upgrade Zigbee Coordinator firmware, add USB extension cable + use a USB 2.0 port. See:
https://github.com/home-assistant/home-assistant.io/pull/18864 → https://github.com/home-assistant/home-assistant.io/commit/970295a277e8f01d3ee39eeeaacf453625b988d3
also read and follow:
If using Home Assistant 2022.4.x then there are bugs with ZHA quirks in that are being worked on, see
So downgrade to Home Assistant 2022.3.x or wait for a fix.
How do you send an OTA update to the button?

I have exactly the same problem with Ikea Symfonik sound controllers. One works great, the other added later does not have any events. I’ve reported this here:
The OTA udpate documentation is here Zigbee Home Automation - Home Assistant … I have set the configuration.yaml to auto update Ikea but the instructions to manually update are a little too complex for me to understand where and how 
I’m having this same issue with some shortcut buttons (3 not working and 2 working) and two STURBAR remotes. ZHA says it finds them but nothing works and the battery just says ?
If you want to perform manual update of only some specific IKEA device(s) instead of automatic update all all IKEA devices then you first need to find copy if the OTA firmware image version for the specific device that you want to update, see ex:
https://github.com/zigpy/zigpy/discussions/660
More links here:
https://github.com/zigpy/zigpy/blob/8fefb7c8cf327858c35002a66c3e3cac31fdafc4/zigpy/ota/OTA_URLs.md
Then to update manually copy OTA images files to the otau_directory after you created as such folder:
https://www.home-assistant.io/integrations/zha#ota-firmware-updates
zha:
zigpy_config:
ota:
otau_directory: /path/to/your/ota/folder # Utilize .ota files to update everything else
FYI, looks like someone is working on updating the ZHA quirk for IKEA’s SYMFONISK remote here:
I’ve got a similar issue, but in my case the button was working then stopped. I have performed a reset and re-add, but no luck. I bought a new button yesterday thinking I just had a bad button, but the new one is exhibiting this behavior too.
I hade the exact same problem as the rest of you and then it just started working after me tinkering with the button by re-paring it? 
It does seem that the Ikea buttons, when used with Home Assistant, are somewhat flaky and I have absolutely no idea where the issue lies.
I have a reasonable number (18) of the Ikea shortcut buttons and if I pair one or two of them up then they seem to work (albeit the battery level reporting seems very hit and miss as to whether you get anything shown or not) - I created a test automation just to toggle a socket on and off when a shortcut button is pressed and added buttons to HA (using a Sonoff Zigbee 3.0 dongle but I have several others and they all seem to do the same) adding them to the test automation as I go and I end up with earlier buttons no longer triggering the automation.
I have a single “on/off” button and that seems fine but I haven’t got multiple ones of those to try.
I have just dug out my Ikea Tradfri gateway (which I’ve had for several years but never used) and paired up all the switches to that to see if they’ll update their firmware … they all look to be on 2.3.15 firmware (even though some were bought a few years ago and some were bought two months ago) and the current firmware appears to be 2.3.80 … they’ve been set up on the gateway for a week now and about half have updated to 2.3.80 so far but oddly both the ones with 2.3.15 and the ones with 2.3.80 show as “Up to date” even though so far 8 of the ones that were “Up to date” on 2.3.15 have updated to 2.3.80 … and of course there is no way to force an update, you just seem to have to wait for the random interaction of cosmic rays to make that work.
So, unfortunately, it seems that the Ikea Tradfri stuff is flaky as hell at the moment … and using the Tradfri Integration with the proper Gateway seems to only give me the battery levels for all the devices, nothing else, no way to actually use any of the buttons, switches or sockets but perhaps that’s because the Gateway firmware is out of date? Who knows? The software reports that it’s “Up to date” but it also shows the remaining 8 shortcut buttons that have 2.3.15 on them as “Up to date” however another 4 of the 2.3.15 shortcut buttons are also showing as “Updating” as did the ones that are now on 2.3.80 so who can be sure?
Today I found out that my two shortys start to work after i pressed the pairing button for a long time. Everything was already set up. They were paired and there were test automations. Pressing thepairing button first the button started to light up. After several seconds the button flashed a few times and afterwards it just worked. I didn’t even pair them again. All the automations I set up with the blueprint worked. I needed 6 months for this solution but now I’m really happy it functions now as intended.

Hello, I had the same issue that two buttons were working fine and two others were registered in ZHA but not firing clicking event. I have figured out that after connecting them to ZHA I had to connect them to an other IKEA device (bulb, switch) by long clicking the pairing button for some seconds next to it. That would not have any effect to the devices, but triggered events by the buttons are recognized by HA.
Maybe this would be a workaround for people you who have some other IKEA devices lying around

I can confirm.
Pairing with bulbs solved the issue with IKEA shortcut button.
Plus when you do that with IKEA remote with 4 buttons STYRBAR it can control the lights even when Zigbee coordinator is down.
Thanks m8
My man, this did it for me 
The identical issue with it pairing to ZHA but not showing any click events. Held the pair button down for ~30 seconds and it magically worked after that. No re-pair needed. Also (I think) if you accidentally press the front button while trying this (ham fisted fat fingers) it won’t work and you have to do it again.

Hello
I had the same issue and was pulling my hair out trying to understand, I the end i found that this was down the the firmware version on each device.
The way i got round this was by pairing the device to the Ikea hub (account required) then update the firmware.
This worked and I now have two shortcut button in my system connected to zigbee using ZHA.
Hope this helps.
THIS was THE important missing piece! With this IKEA Trådfri Shortcut button it’s not very easy to press & hold the reset button on the inside while NOT simultaneously pressing THE button, too!
So, be careful and JUST press the reset button for app. 30 seconds.
It helped me, too. No need for an IKEA bulb or some account or the IKEA base station or a firmware update – at least for me.
Thank you!! This did the trick to restore button click sensing.
