Possible to avoid networkmode: host?

[AAPohl]

Hi, configured evcc locally and it works, moved it to docker and got my sma home manager only working with 'host' most. Normal Mode has some Speedwire error.

Is there anyway to get this working w/o Mode 'host'?

Maybe with macvlan. But that needs a good understanding of networking and maybe never has been tested before.

By normal mode, I assume you mean default, which equals bridge mode.
As bridged docker networks are not visible outside the host, the behavior is different. I am not sure how SMA/speedWire works. But if it requires equipment to open a connection to evcc, this likely can still work, but would require you to forward ports.

It really depends on what issue you are actually trying to solve. If you have port conflicts between host and container in host mode, try bridge mode and port forwarding. You will have to adjust the other side (SMA?) to use the externally forwarded port.

If the issue remains you could try MacVLAN as Stefan already suggested. That would make your evcc container appear visisble as a "normal" host on the network, with it's own IP. With that setup, anything should be possible, since from a networking perspective this effectively is the same as running evcc on a dedicated physical box.
