Lost all Homebridge accessories after network switch
I've changed my Raspi network layout at home from WiFi to Ethernet and after that all Homebridge accessories are gone in the iOS app, only the bridge itself is there. Changed everything back like it was before without any luck, all accessories are gone :-(

What's the problem here?

Is there any trivial fix to bring them all back?

I really do not want to start from scratch the 3rd time in 1 year homebridge usage.

I'm using Raspbian Buster on a Raspberry Pi 4b with Homebridge 1.2.5 and FHEM plugin.

Thanks.
