No integration of remote devices via Zerotier network

Hello, I would like to connect devices (Shellies, Reolink-cam) which are located at a remote location (holiday home).

Both locations are connected by a Zerotier network, the clients run on separate raspis, not HAOS. I can well ping the devices out of HAOS, but I cannot add them to a Reolink or Shelly integration (not found). Local cameras or shellies are no problem.

Thanks for some help…

Did you try the zerotier addon?

Yes, the add-on is running and connected to the network. Still no success.
