Connecting to remote URL when on local network

Actual behaviour

All happens when I’m connected to my home network. When I launch the app, it initially connects to the local URL and it responds fast, as expected. If I move the app to the background and open it again after a while it says “Connecting to remote URL” and the response is much slower so it is clear that it gets it data over the internet. If this happens and I completely close the app and reopen it, it connects to the local url again.

Expected behaviour

I expect the app to always connect to the local url while on the home network.

Steps to reproduce

Where can I get it?

Maybe if we’re on a local network and can’t connect to the local server, we should regularly retry to connect to the local server?

I think the problem is that the app sometimes failes to connect to the local server, connects to the remote one and as long there is a connection to some server, the app doesn’t try to connect to a specific one (with exceptions for e.g. notifications that are always fetched from the remote server). I guess https://github.com/openhab/openhab-android/pull/780 could fix this issue.
