Now we need city water again for our plants in Dallas I dusted off the controller.
I have the arduino opensprinkler running 2.1.5 which I flashed yesterday. On rebooting I was overjoyed that the correct date & time was plucked from the internet, but alas less than 24 hours later and the time is already 30 minutes behind actual time.
I only see a manual update option. Is there no automatic date/time update built into 2.1.5?
Ps. 2.1.5 was a huge jump in features and UI. The android app seems to work great.
5 minutes faster seems quite off. It also seems to indicate the firmware is not getting NTP sync correctly. First, check if your ‘NTP Sync’ option is checked; next, does your controller have access to the Internet? Without Internet access it can’t sync with NTP server properly.
