Beta Version 3.3.0 (2026/06/18)

I haven’t received that version yet; I’m still stuck on 3.1.1. Both the bridge and the app say it’s on the latest version! Considering the release date, it’s been quite a while!

[KwayLi99]

Sorry for the confusion. The new version is expected to be released today. I’ve unlisted the post for now and will republish it once the update is officially available

With the new version 3.3.0, when I activate any security mode, after the classic three beeps that warn me that the selected mode is being activated, the beeps continue indefinitely!!!
The only solution is to lower the volume or restart the Bridge!!!

[Minnie]

Hello, we sincerely apologize for the inconvenience caused. We take your feedback regarding the “alarm sound continuing indefinitely after security mode is activated” very seriously. To help us accurately identify and resolve the issue, could you please provide the following details:

1. When setting up the security mode, did you configure any specific sub‑device as the trigger condition? Did you set the alarm duration to “continuous”?

2. Have you experienced this issue before, or did it only start occurring after upgrading to the new version?

We apologize again for the inconvenience caused. Thank you for your cooperation and understanding!

[r.brizzolesi]

solo dopo l’aggiornamento alla versione 3.3.0 !

[Minnie]

We would like to understand some details about your security settings. Could you please let us know:

1. Which specific sub‑devices did you set as trigger conditions when configuring the security mode? (e.g., door/window sensors, motion sensors, etc.)

2 .Did you set the alarm duration to “continuous” (i.e., indefinitely)?

If convenient, you may also submit logs via the local web page or the eWeLink app, which will help us locate the issue more quickly. Thank you for your cooperation!

[r.brizzolesi]

Il suono che si sente non è quello dell’allarme ma il Bip che fa di solito quando si inserisce o disinserisce l’allarme , solo che di solito fa tre Bip , ora non smette più !

[r.brizzolesi]

Ho notato anche che pur avendo impostato come durata del suono di allarme 2 minuti , ora se scatta l’allarme il suono di allarme dura solo 1 secondo !!!

[Minnie]

Hello, thank you for your feedback. We sincerely apologize for the unsatisfactory experience you have encountered.

Please submit the device logs via the local web interface or the eWeLink APP, and select the ZBBridge-U device when submitting. Upon receipt of the logs, our technical team will immediately conduct issue analysis and troubleshooting.

[r.brizzolesi]

Salve.

Dopo l’aggiornamento del Bridge-U alla versione 3.5.0 il problema rimane !

Dopo aver disattivato l’allarme il Bridge continua ad emettere il Bip-Bip !!!

[r.brizzolesi]

Still no solution to my problem?
But it’s possible that no one is using it as a surveillance device without having the same problem as me.
I don’t know how else to explain it: whether I enable or disable security mode, the Bridge continues to beep endlessly!!!

[Minnie]

We sincerely apologize for the inconvenience this has caused you. We have not yet received the logs you submitted, and our technical team has been unable to reproduce the issue you described, where the device continues to emit a beeping sound after the security mode is enabled. To further investigate and resolve this as quickly as possible, please follow the steps below to submit your logs:

Please submit the system logs via the local web page or the eWeLink App. When submitting via the eWeLink App, please select the ZBBridge‑U device and make sure to check the “Upload logs” option. After submission, please let us know your ticket number. Our technical team will analyze the logs and provide a solution as soon as possible after receiving them.

Thank you for your cooperation！

[r.brizzolesi]

I submitted the feedback and this is what appears in the app

[r.brizzolesi]

Where can I find the ticket number?

[r.brizzolesi]

I ask you if it is possible to go back to the previous firmware

[Minnie]

Hello, thank you for providing the logs. We have received the device logs you submitted, and our technical team will analyze them as soon as possible to identify the issue and aim to fix it in a future update.

Regarding your question about rolling back to a previous firmware version, we currently do not support downgrading to earlier versions. This is because firmware updates often involve changes to the underlying protocol, security patches, and data format, and rolling back may cause inconsistencies or other unexpected issues.

We will investigate the problem you reported promptly, and if it is confirmed to be a firmware bug, we will release a fix in a subsequent version. We appreciate your patience and understanding.

Thank you again for your support and understanding!
