Some SNZB-03 going off

Hello!

I have 3 apartments with zigbee bridge pro and 8 SNZB-03 each.
In every apartment 2 or 3 SNZB-03 are going offline, even if I changed the battery, always the same. Any solutions?

Thank you in advance.

Hi,

What’s the distance between the bridge and the SNZB-03?

In my case, if I put it more than 5 meters away (with a single wall between them), it goes offline.

Kind regards,
Renato

Hi,
I have the same problem, 3 SNZB-03 in my house stairs, one for each floor. The zigbee bridge pro is in the middle and the distance from bridge and any device is about 2-3 mt. with a wall between the bridge and the SNZB.
I try to change the channel of the bridge, the channel of 2.4 Wifi without results.
About every week anyone goes offline.
Any suggestion?
Thanks
Kind regards
Fabrizio

Same for me but when a movement wakes it up it is back alive and working fine until it appears sleeping some time later… Regards
