Loxone iOS app slow remote connection, local connection is fast

[johnsmith_]

Hey!

I have an annoying problem. Using the Loxone iOS app, every time I open the app it connects via remote connection, which is really slow, usually takes 5-10 seconds until it loads the states and I can control my stuff, it's annoying. The good thing is, if I'm on my wifi at home, I can add the miniserver in the app and it connects locally, and it's basically instant every time I open the app.

I understand that there's a network delay and such when I'm going through Loxone's cloud, it's okay. My issue is that once I leave the house and I disconnect from my wifi, the app goes to remote connection - so far so good, but when I get home, get on my wifi, it forever stays on remote connection until I manually search for the miniserver in the app and login again.

Is there a way to make the app switch to local connection automatically when I'm on the same network? This huge delay is really annoying when I'm actually 10 meters away from the miniserver and on the same network.

Having the same issue. Only it takes my remote connection like 30 seconds to get the stats! Usually 5-10s, but quite regularly 30s and more!
Thanks for aby hints.

The long connection time is unfortunately is a long standing issue (past 2 years at least), and is caused by Loxone DNS. So it applies to External access to your miniserver via both "Remote Connect" and "Loxone Cloud DNS". You can only avoid it by having Static IP and not rely on loxonecloud.com at all. Or Loxone can maybe fix this at some point

The problem is quite severe and you can expect it to happen every ~45minutes and last for about 5 minutes: your connection times will be 7, 15 or even 30 seconds. I have found that by connecting every 1 minute to 4 different miniservers and measured the connection times (the test was done from Google Cloud machine which has excellent network connectivity; the 4 miniservers are located in different geo locations and include the official Loxone Demoserver).

But then, to avoid even the connection times to actual miniservers, I simply fetch only the "redirect" information with https://dns.loxonecloud.com/?getip&json=true&snr=<miniserer_serial_number>.

You can see the response times in the char below (X axis is the timestamp of the connection attempt, Y axis is the duration of that lookup):


My Loxone partner tried to file this as bug with Loxone, but as far as I know, the reply was that this is caused by 3rd party network connection(!!!) or maybe that this won't be considered "know issue" because these are considered issues of short duration (see "What is a known issue?").

Do you also experience connection issues? Please let me know in this poll. Thank you!
