#Can't setup Matter Devices

I have HAOS, matter server add-on, everything up to date. Just bought my first matter device (GE Cync under cabinet lights). Went to add matter device, scanned code. Saw the picture of the device, tried to pair. Fails after a few minutes.

GE docs mention nothing about a pairing mode. I opened the box, plugged it in, and can't connect. I have Bluetooth on already to provision onto the WiFi but nothing happens.

What am I missing?

hey can you add more details like what smart phone/app/hub you were using? and what the error is?

I have successfully paired three of these lights with HA about a year ago. They have been rock solid. I do remember having some issues pairing. I think I factory reset the ge lights a few times

describing at which point exactly in the pairing process (what's written on screen just before it fails) can help to pinpoint where it's going wrong. a description of how your home wifi network is set up and how home assistant is connected to the network could help too.

#

and yeah, in some cases you might need to reset the device to convince it to let you try again.

Hi all! Thanks for your input - I am using the Home Assistant App on Android, Galaxy S22+. My network has IPv4 and IPv6 enabled, and HAOS runs on an HP thin client connected by ethernet. Network is the home-brew version of a 'business' setup - 2.5Gbps PoE switch with multiple PoE WiFi 7 access points throughout the house. I use the same SSID for 2.4, 5, and 6G bands.

What happens is I scan the device QR, it shows me a picture of the device, then I choose to connect & the app spins for a bit before saying it couldn't connect and recommending some options like toggling Bluetooth. I've done it with my phone nearly laying on top of the device.

Connecting to it with bluetooth in the Cync app worked perfectly fine though, so I know it's capable. I did notice that the Cync app asked for permission to control/use bluetooth, but HA never did - wondering if there's a permission issue? But not sure what to check

#

I'll also try factory reset now that it's connected to Cync and updated

which phase you had issue with connecting issue; does it say failed to connect to your device or failed to connect your device to your Wi-Fi?

If it’s the former, your device is not discovered as is in pairing mode

FWIW, I have a separate SSID that it 2.5 only that I use for all my IOT stuff. Then when I pair devices using my phone I force my phone to the 2.5 SSID. Some IOT devices may be confused with SSIDs that are multi frequency

the Cync app might even be talking to the bulb directly with bluetooth, without connecting it to wifi at all.

#

but the matter setup does require connecting to wifi.

#

vendor specific apps often are able to pair to devices at any time, even when the device isn't ready for matter pairing. In general, devices only support matter pairing discovery if they aren't already paired to matter, and only for a short period of time after they are powered up (this is a security feature)

#

If a device is already paired to matter, you either have to "share" it from the matter controller it's connected to, or reset it, in order to make it discoverable again.

#

note that if your wifi is in a different subnet from home assistant, you will probably run into additional problems later in the pairing process. HA needs to do mDNS queries to find the matter device, but mDNS queries are not routable between subnets.
