@reolink-lorenz Hi. When I installed the v3.1.0.764 firmware on my two 510WA, the integration from Home Assistant stopped working completely.
When I reverted to v.3.0.0.494, the integration started working again.

I know, that it's not your problem that third party integration stops working, but I thought I would let you know in case something is not right regarding this in the beta version.

Have a nice day

/Lars.
