Firmware 2.1.2 does not have the 3 program issue.
Let’s isolate the problems first. You reported that 1) you can’t connect to OpenSprinkler remotely; 2) the weather adjustment isn’t changing. For question 1, are you able to access it when you are at home? If yes, it sounds like OpenSprinkler cannot reach the Internet, and that will also explain why the weather adjustment isn’t changing. If you can’t access OpenSprinkler while you are at home either, it sounds like it can’t connect to your router. Click the first button (B1) to check if its IP address has changed.
