I’m controlling my outdoor lighting with OpenSprinkler and a relay. A couple months ago, I noticed that my lighting was not on at dusk but should have been on. When I checked my OpenSprinkler, the time was incorrect. I rebooted it and it got the correct time. The next day, I noticed that the lighting was on at 10 AM. Checked OpenSprinkler and the time was off by several hours and several minutes.
I changed the NTP IP to a different NTP IP and the time updated properly. Forgot about it until today when I noticed the lights were on at 11 AM again. I forgot to check until it was dark out and I noticed the lights were not on again. It was 8:02 PM ET but open sprinkler was showing 9:23 AM ET. I pointed it to my Windows Domain controller and the time updated to 11:31 AM ET…WHAT? Rebooted and the time was correct again.
Anyone else having this issue?
EDIT: It’s only been about an 14 minutes since I last rebooted it and the time is already 7 seconds slow from my NTP Server.
App Version 2.2.0
I discovered that my OpenSprinkler had the wrong time/date this morning and rebooting did not fix it. I finally looked up IP addresses for public NTP servers and changed mine to a new one. Immediately after saving the change the time/date were correct. I don’t recall where I got the old IP address for my time server but I’ve been using it since I first installed years ago. The time has been wrong for a long time but today was the first day I expected it to run this year.
App Version: 2.2.1
Hardware Version: 2.3 – AC
I changed the ntp server on mine a few days ago and it was good for a little while. Last night, I noticed my OS controlled landscape lighting was off at 9 PM. Checked just now and the time shows 3/31/2021 17:28 but it’s currently 4/1/2021 10:30.
