Pls help: replacement of gateway

Hi Smanar,

thanks for your reply.

I am desperate at the moment.
Today morning, the network from yesterday (all lights connected at least) has disappeared.
There is only one light left…

What’s wrong with ConBee III?!
I do not have the time to spend weeks with it.

Answers to your questions:

No, I do not have a capture from deconz.

Nodes: I am not familiar with the vocabulary.
If a node is a light or a switch or a sensor:
The lights were connected ans visible.
I was not able to connect any switches. So they were also not visible.

Yes, I always worked with phoscon APP. But I am not a pro, so I installed the system and used it. No adjustments for years.
In the Phoscon APP I did (2022): Gateway - Backup Optionen - Backup erstellen and saved that file on my HDD.
Also in the Phoscon APP I tried to load this file (2025) - and got all the nodes without connections.

So I reset the ConBee3 and connected newly…

Attached the “imported” nodes - which did not work and the newly connected lights - which are missing today:


I already have tried the GitHub Network help (Disconnect - Save etc. Connect.
No Change…

Thanks!
