I treated myself to the OpenSprinkler last year and use it to run several irrigation circuits in the garden. Of course, I deactivated this over the winter and didn't bother with it any further. Now I would like to start it again and have the problem that the OS does not maintain the WLAN connection. I can connect it to my WiFi just fine, but after a few minutes it's offline again. I didn't have this behavior last season. It was always online and worked perfectly all summer. Nothing has changed with the WiFi. Still the same Fritzbox in the same place. Does anyone have an idea what this might be?
In my experience it depends on the environment. Even if you haven't changed anything, additional WLANs have probably been created around you that are now reducing the range.
Unfortunately, this WiFi contamination is increasing more and more and the only thing you can do about it is to try even harder: with your own WiFi repeater.
