SNZB-03 and SNZB-01 randomly appear offline on Zigbee U but scenarios still work

Welcome to the Zigbee Bridge Ultra category!

I have an issue with the Zigbee U connected with 9 devices. From time to time, some of them appear offline, but the scenarios are still active.
Then, the next day, they appear online again without doing anything.
This only happens with these two devices: the SNZB-03 (old model) SKU SON_SNZB-03 EAN13 6920075776119 and the switch SNZB-01 SKU SON_SNZB-01 EAN13 6920075776096.
There are no problems with the other devices.
Do you have any idea?
Thks You.

Additional information: triggering the devices (motion detection or pressing the switch) makes them appear online again. It looks like they go into some kind of sleep or standby state when they are not used.
I should also mention that I monitor the devices using the eWeLink Android app.

Hello,
We sincerely apologize for the inconvenience caused. Regarding the issue you reported, our team has already implemented optimizations.
We recommend upgrading your ZBBridge-U to the latest version, 1.19.0, to see if this resolves the problem for you.

Thank you for your continued support!


Thank you very much for your responsiveness. !

I will check very soon

How’s it going, bro? Did the latest version fix your offline issue?

Hello, no, the release 1.19.0 doesn’t fix the issue.

When the devices are not trigerred they appear as “offline” after one moment. But the scenario are always active. When the devices are triggered once again they are coming alive…

Same problem here, several offline devices, mainly doors sensors and scene buttons. I’m giving up on ewelink and leaving for tuya which is better

The only sensors that work normally on this bridge are the snzb-04p or newer. It’s a shame to do this with consumers. I won’t pay for the advanced plan anymore because it doesn’t work if the devices appear offline. The sensors come back after being triggered, but if they are offline it is not possible to see the records

Hello RayZane, of course i will give you all necessary information.
But first how to get the local web interface as shown in your image. On my PC eWeLink Web , is not given the same interface than your. For example it is not possible to access to the support & maintenance logs .

So could you help me to know how access to this log ?

After I will give the the models which causes issues.
The first is SNZB-01 and I sand you the picture of this sensor.
The second is SNZB-03 (old model) SKU SON_SNZB-03 EAN13 6920075776119

Thank you for your willingness to provide the logs. Please follow the steps below:

  1. Open the Gateway Settings page in the mobile app, scroll to the bottom, and find the Gateway IPv4 Address.

  2. Open a web browser, enter that IP address to access the local web interface, go to the Gateway Settings page, and click to download the gateway logs.

  3. Send the logs to me via private message and include the approximate time the device went offline to assist our technicians with troubleshooting.

Thank you for your support!

Ok, Log sent via private message.
Have a nice day

This morning I have updated the bridge with 1.19.2.

Got it, bro. I’ve passed this on to the tech team. Have a great one!

Hello,

I have already answered on this discussion, but… no probleme

The first is SNZB-01, have a look on the picture
The second is SNZB-03 (old model) SKU SON_SNZB-03 EAN13 6920075776119

SNZB-01 ID is a48004e4c5

SNZB-03 ID is a48003e695

Thank you for providing the information. However, what we need is the device ID of the ZBBridge-U gateway itself, not the IDs of sub-devices (such as SNZB-01/03). Could you please check and provide the gateway’s device ID? Thank you again for your support and understanding.

OK gateway device id is : 100281f783

best regards
