Matter over Thread Issue – Eve Door & Window

Built-In Apps and Drivers
1

I’m experiencing an issue with an Eve Matter-over-Thread contact sensor where Apple Home receives all contact events correctly, but Hubitat intermittently fails to update the contact state.

Environment

  • Hub: Hubitat Elevation C-8

  • Hubitat Platform: Latest release (fully up to date)

  • Device: Eve Door & Window

  • Model: 20EBN9901

  • Firmware: 3.2.1

  • Transport: Matter over Thread

  • Driver: Built-in Generic Matter Contact Sensor

  • Multi-Admin: Apple Home + Hubitat

Expected Behavior

When the contact opens and closes, Hubitat should immediately update the device state and generate the corresponding events.

Actual Behavior

  • Apple Home always reports both open and closed immediately.

  • Hubitat will receive one state change but fail to update for the opposite state.

  • During the failure, the Hubitat device page remains in the incorrect state.

  • Live Logs do not show the missing contact event even with debug logging enabled.

Network Troubleshooting Already Performed

I spent considerable time ruling out networking issues.

  • IPv6 is fully functional.

  • Thread network is healthy.

  • Apple Home continues to receive events instantly.

  • Because Apple Home receives every event correctly, I do not believe this is a Thread, IPv6, or RF connectivity problem.

Matter Logs

I captured Matter debug logs during the failure.

The raw Matter traffic shows both contact reports being transmitted, including the contact state change that Hubitat ultimately fails to reflect.

However, the Hubitat device debug log does not generate the expected corresponding contact event.

This suggests that:

  1. The Eve sensor is transmitting the report.

  2. Hubitat is receiving the Matter report.

  3. The event is not consistently being translated into the Hubitat contact device state.

Files Attached

  • Matter protocol log captured during the failure

  • Hubitat device debug log

  • Screenshots if needed

Additional Information

The sensor previously worked correctly. The issue developed without any intentional configuration changes.

I also tried:

  • Reinitializing the Matter device

  • Clearing device history

  • Enabling full debug logging

  • Verifying IPv6 connectivity

  • Confirming Apple Home continues to receive all events correctly

None resolved the problem.

Could you review the attached logs and determine whether this is a known issue with the Matter implementation or the Generic Matter Contact Sensor driver? If there are any additional diagnostic logs or beta firmware that would help isolate the issue, I’m happy to test them.
