Same problem here in Italy. Just set up my new sprinkler plant: everything work, I can access opensprinkler from outside, but no weather icon in the app, even if the diagnostic states that it can update weather. Same google problem “This page can’t load Google Maps correctly, do you own this website?” But it seems to select correctly, I don’t know if that is related to the missing weather icon.
Another point about this issue, maybe not related: I receive a notification that states that the remote access is not enabled, please click here to solve… but this isn’t true. I’ve already done port forwarding in my router and I can access to Opensprinkler correctly. Could it be because I’m in a double NAT enviroment? Could this also explain the missing weather icon? Don’t know. But I’m sure that my network is correctly configured and I can connect from outside to my server, pc, cameras and so on.
Just to add a clue, to the developers.
Sorry for my poor English. Thank you for your help.
