I need to highlight the exact problem more clearly:

• Tapo H100 Hub does not appear at all in the Deco app — not in the device list, not even in the IoT network view.
• Meross Matter Smart Plug shows the same behavior — it is connected and working in its own app, Google Home, and Apple HomeKit, but completely missing in the Deco app.

So this is not just about Tapo integration. The issue affects other Matter devices (Meross) as well, which proves the problem is on the Deco Matter implementation side after the latest firmware update.

Please escalate this to R&D urgently, since Matter devices are working fine everywhere else but not showing up in the Deco app.

Issue Description:

After the latest firmware update on Deco BE65, I am facing multiple problems with Matter devices:

1. Tapo H100 Hub – It is not detected at all in the Deco app. It doesn’t show up in the IoT list or the general client list, even though it is online and working fine in the Tapo app.
2. Meross Smart Plug Mini – This device was added before and worked fine, but now it is shown as connected with a corrupted/invalid IP address (fe80::xxxx). It is not active anymore and even when I select Remove Device in the Deco app, it cannot be deleted from the list.

Both devices (Tapo H100 and Meross Smart Plug Mini) are visible and working normally in their own apps (Tapo / Meross) and can also be added to Google Home and Apple Home via Matter without issues. The problem only occurs inside the Deco app after the latest firmware.

Please investigate whether this bug is coming from Deco firmware or Deco app, because it affects devices from different brands (TP-Link Tapo and Meross

Please escalate this issue to R&D team because it affects multiple Matter devices (both TP-Link Tapo and Meross). It is clearly introduced after the latest Deco BE65 firmware update.”

1. Previously, the Meross Matter device could be added to Deco without any problem.
2. The Tapo H100 Hub could also be added, but it did not work as a proper bridge. Still, it appeared in the Deco app as connected to the IoT network.
3. After the latest firmware update, the situation changed:
   • Meross Matter devices can no longer be added,
   • Tapo H100 does not connect via Matter anymore,
   • Even though these devices are connected to the network, they no longer appear in the Deco app’s network list.

5. Important detail: I am not pairing Deco with other platforms like Google Home or Apple Home. All devices are managed directly through the Deco app.
6. Before the update, Matter devices were added successfully, but now the process fails and the devices cannot be connected.
