Last month, I’ve bought a Homey Pro 2023 since I wanted to have more flexibility (before then, I only had a couple of Nanoleaf matter-bulbs, and Eve matter-switches and matter-sensors in Apple homekit). Since update 10.3.0-rc.7 the Homey Pro 2023 functions as a thread border router. I expected this to be good for performance (with our Apple TV as thread border router it was quite slow sometimes) so I’ve updated homey to this version and moved all matter-devices to Homey.
However, since yesterday some bulbs and switches are showing ‘matter-error 0x00ac’. I’m not sure how this can be fixed (preferably, without re-adding the devices) and as far as I can see internet does not have an answer! Does anyone have an idea? It’s especially strange, since some devices are still functioning correctly.
Thanks in advance for your suggestions 
Strangely, the problem seemed to have fixed itself (or maybe turning off the power for 10 seconds did the job). I’m still interested what this error-code means and how the issue usually can be solved.
/**

#define CHIP_ERROR_INTERNAL CHIP_CORE_ERROR(0xac)

Probably even Athom won’t know the exact reason.
Hi there, getting the same error message 0x00ac… this came as i am trying to bind my aqara hub g3 to homey pro (2023). All updates are the newest, tried many times, I see a brief flash of two icons connecting and then comes the message…
My third homey pro (2018 and 2019) and I am quite disappointed by the performance in general, even though the matter error is a major concern and annoyance.
Anyone can help? The hub is recognised in home kit but just not in homey
I am also getting this error but the device seems to be working. I have 3 of these Eve Motion sensors and they are all doing the same exact thing.
When I long press for device details, it shows motion, illuminance, and battery details.
No Pro 23 here, but is it possible to restart Matter or Thread?
I got a Matter lock connected to Home Assistant, and every once in a while it’s unavailable too.
It’s “solved” by an automation:
if lock = unavailable
then restart Matter
We had a power outage the other day and Homey restarted. This error went away.
I have had similar experience with Matter devices and have restarted Homey to get them back up and running. This seemed to work and over time those devices have become more reliable.
At the moment I have a nano leaf matter light globe that I can’t communicate with. I feel that it is a comms issue in that it is the furtherest away device, even though it is next to other devices which are working over wifi.
If I bring the globe nearer to homey (or the wifi router) it starts to comm7nicate again.
Is there any fault finding steps I can take? Is it possible to see matter devices working over wifi using your router admin screens? I can’t see anything in the developer app that helps.
