Hi Ray
Apologies for not being completely clear. We upgraded the OS on our Wireless Router that provides connectivity across our site. It was when we rebooted the wireless router after the upgrade that we noticed the behaviour that I have described. I’ve since been able to replicate the behaviour by going into our Wireless Router and temporarily disabling the wireless interface and then re-enabling it. After wifi comes back up, the OpenSprinkler 3.0 device reconnects automatically without any problems. Sadly any programs that are running when wifi is lost are stopped and don’t automatically restart when wifi reconnects.
