I’m running with a recent snapshot of the matter binding.
Can you confirm the version that shows in the console? What OTBR are you using? You mention Alexa, but how did you pair it? with Alexa first then openHAB or somehow else.? You mention “often retrieve the list of connected matter fabrics”. i’m not sure what that means, can you pm logs?
I’m running these versions:
OH 5.3.1
openhab> list -s | grep matter
362 x Active x 80 x 5.3.0.202603210352 x org.openhab.binding.matter
Here’s my Thread network per Android phone typing in the settings area “thread” and letting it find everything.
As you can see, I’m not seeing OH’s thread entry and you were the first setup for Matter on the network. I do see OH thread entry on Aqara’s hub so it does exist.
I merged IKEA’s Matter network onto Aqara’s hub per the video I posted on a separate thread.
I’m using Aqara M300 Hub as primary OTBR.
I tried to get my 2 Echo’s to merge onto Aqara matter network w/o luck. Lots of people having issues doing this, Alexa wants its own Thread network (ugh).
I do tag a bunch of items (using a file) to have Alexa see my dummy switches in as Matter switches which is working.
I would think that we could tell OH what thread network to use?
Best, Jay
The version is 5.2.0.202603160407.
I first paired it using the Alexa app and then added it to OH using the pairing code from the Alexa app.
I’m using an ESP thread border router flashed using the image on your website.
“often retrieve the list of connected matter fabrics” - I’m referring to the thing action in OH which allows you to list the connected matter fabrics/controllers the device is connected to (sorry away from my PC and don’t remember the exact terminology).
I have searched the forum, but could not find anything relevant, so apologies if answered elsewhere.
Matter over Thread and native Thread groups; how does that relate to the familiar Zigbee groups that appear as group Items in the Inbox, at least when using the Deconz binding?
AI answer might hint that this is not as for Zigbee, as a Thread group is set up between nodes and given just an IP address and is not an entity as such? (using chip-tool and OTBR)
Why I’m, asking is that I want to get my head around this and understand what is possible for Thread in respect to Zigbee.
I will start out the easy way and just make an Item group and see how well synchronized several bulbs in such a group are when dimming and changing ambient color. If the response is good, the need for native Thread groups is not as urgent.
