I have owned an OpenSprinkler 2.3 DC for several years and love it. My controller is connected to the network using its Ethernet port; and the device started becoming inaccessible on the network every 2 to 3 days after upgrading to firmware 2.1.9 back in 2019. I was tempted to downgrade to 2.1.7; however I enjoy using the ET algorithm introduced in 2.1.9.
For the last 8 months my workaround has been to plug the controller into a timer that powers down the device daily for 15 minutes. I have not been locked out of the device ever since. Anyhow, I want to give props to Ray for taking the time to research the ethernet lockups. I look forward to the day when I can remove the timer. Thank you!
