Trouble adding IKEA Bilresa Matter Switch to Polisy

Hi,

I use and enjoy my ISY devices every day. I have a Polisy Pro running 6.04 with the internal zwave/zigbee matter dongle.

Background:

I am looking to replace a couple of aging Remotelinc 2s. IKEA is now selling a matter capable Bilresa two button switch for $6. I got a couple and I think they are nice.

I have a matter network with thread over wifi running in my house with Home Assistant. The Bilresa switches pair/add to matter OK on Home Assistant.

I have Zwave and Zigbee devices paired with my Polisy. I have never tried to use matter on my Polisy; no devices added.

I understand that to add an already paired matter device to an additional matter "server" is not just scanning the original QR code but requires getting a new pairing code for the matter device from the first/existing matter "server".

I am unable to get my Polisy to pair with the Bilresa switch. I have tried several ways.

Open Home assistant, ask to share Bilresa, get pairing code. Open UD mobile, verify Matter is enabled. Ask UD mobile to add new (this would be first matter device on Polisy) matter device. UD Mobile asks for pairing code - I enter the sharing/pairing code from home assistant. After several minutes the request times out. Bilresa not added. I have tried adding Bilresa using both UD mobile on android Pixel phone and on iOS iPad. Bilresa does not add. Tried with Bilresa within inches of Polisy. No Bilresqa added.

At a different location I have successfully added/shared a different matter Bilresa to two matter "servers" ((Nest hub and Home Assistant) on the same network. Bilresa is seen and works with both matter "servers."

Is Matter really running on my Polisy? What other ways should I try adding/sharing Bilresa to my Polisy?

Any suggestions?

Thank you for you advice.
