I have home assistant running on a Raspberry Pi with a HA Connect ZBT-1 as the Thread Boarder Router, and after adding ~25 devices, I’m no longer able to add any more Matter-Over-Thread devices without running into the following screenshot:
I’m quite lost on how to solve this. I’ve tried rebooting the pi, re-flashing the ZBT-1, the Pi has an ipv6 address (fd14:.... which is pingable and fe80:... which is not), and mDNS seems to work as I can ping6 homeassistant.local and I’m routed to fd14:.... However, for reasons I can’t figure out how to restore adding new devices or really where to look for general health of the Thread network. Has anyone run into this problem and does anyone have tips in debugging this issue?
I think you are not alone.
I presume you are using iOS Companion App for this and if yes, then here is a GitHub issue that would be worth participating in. The iOS Companion App developer is asking for Logs to help figure out what the problem is.
I am having this same issue, though I’m not able to add even a single Matter over Thread device. The device I’m trying is an Eve Energy. Here are some possibly relevant details:
This is a new HA installation, on Home Assistant Yellow with CM5. Aside from this issue everything else has gone well.
I was able to add all my Homekit thread devices and comission the thread network fine. (Though I don’t see any way in Home Assistant to enumerate these devices from the HA thread border router or thread network stack so I just have to take it on faith. They are working and they were added after a factory reset, so they couldn’t be working any other way I suppose.)
I was able to add my Matter thread devices to HA by using multi-fabric pairing from Apple Home. But this means that my Homekit devices are on one thread island connected to the border router in my HA Yellow, and my Matter devices are on a different thread island controlled by Apple Home. This isnt ideal but it’s working for now.
I have confirmed that I see the bluetooth advertisement in HA from the device when it completes a factory reset and goes into pairing mode.
I have confirmed I can ping6 my HA yellow and the iPhone where I’m running the HA companion app.
I have tried both with and without a WLAN connection configured on the HA Yellow.
I have pressed the “Send Credentials to Phone” button and see the confirmatory check mark but don’t otherwise know what this is doing or how to verify that it has happened.
I have tried sending all the thread credentials to Home Assistant where those buttons are present, though I don’t know what this is doing or how to verify what it has done.
I have tried cranking up the logging levels in the matter server and thread border router, but I either see no output or so much output I can’t find specific log lines for the commissioning attempt.
After wrestling with this again last night or many hours I am considering just throwing in the towel and moving everything back to Apple Home. I was excited for HA… but… honestly I’m seeing way more downsides than benefits right now. I’m a technical user with a pretty good handle on how this is supposed to work and I can’t figure out how to make it work. I don’t think I’m dealing with user error here. (Though never say never of course lol.)
