I expected more from the update and from the gateway. Why do you call it ultra when it’s just the pro version with a few extras.

Hello , Two weeks ago, you developed version 1.19.3 for me to prevent battery-powered devices from disconnecting. This version works very well. Does version 1.2 include the fix you developed?

Thank you for your feedback! We’re glad to hear that version 1.19.3 has effectively resolved the offline issue for battery-powered devices.

In version 1.20.0, we have included specific optimizations and fixes for device offline issues, further building upon the improvements made in 1.19.3. We recommend upgrading your ZBBridge-U to the latest version 1.20.0 for a more stable experience.

The same problem occurs in NSPP when I share devices via matter bridge with iHosts.

We sincerely apologize for the inconvenience this has caused. To better understand and pinpoint the issue you encountered, we would like to confirm the following:

Did you experience a device going offline when using the NSPanel Pro as a Matter Hub in the eWeLink App and then syncing the device to the eWeLink App via iHost’s Matter Bridge feature?

If so, please describe the specific issue in detail and provide the model and device ID of the offline device. You can also upload iHost’s system logs through the “Issue Feedback” section on the iHost website.

The information you provide will help us locate the problem more quickly. Thank you for your cooperation and support!

Hi, after the last update, the matter bridge with NSPP to iHost works. The last thing that needs to be solved is that it does not transfer Sonoff thermometers SNZB-02D and SNZB-02P.

Thank you for your feedback! We are pleased that the Matter bridging function between NSPP and iHost is now working properly in the latest version.

Regarding the issue you mentioned about the inability to transfer data between SNZB-02D and SNZB-02P, please describe the specific symptoms in more detail:

  1. Are these two devices unable to sync to the eWeLink App, or is the status display abnormal after syncing (e.g., data status not updating)?

  2. Please provide the IDs of the SNZB-02D and SNZB-02P devices.

Thank you again for your support and understanding!

I have to prepare it and send.
