Unfortunately there are no Unify cameras, which do not need PoE. PoE is better for sure, but I cannot use it.
In the meantime I solved it.
Is there a connection between SSID and open port?
Reolink changed the default behavior a lot. With the latest firmware all ports are closed, except 9000. With Openwrt-SSIDs you see "UTF-8".
The next challenge is, that there are 2 settings symbols.
There is a "big" main setting symbol in the upper right corner.

Then there is a small setting symbol with every camera on the left side.

And here we go to Server settings. You won't find this, when pressing the "normal / old" settings symbol in the upper right corner as it was with a browser. Now I have to use Windows to access. Default is now, that all ports are closed.
After the ports are activated the UTF-8 symbols at the SSIDs disappear and then I can connect to the openwrt-aps. Last time i had open ports with UTF-8 and openwrt not working.
In the meantime I was able to update to E1_Outdoor_Pro_2838_23102510 with the android phone. Maybe the changes are with this firmware.
