After some consideration I followed Rays suggestion and used remote desktop to control the opensprinkler.
Unfortunately, Due to issues with my Verizon 4g LTE router, I will need to hold off on using the mobile app for now.
But I am looking forward to using the opensprinkler. its a good product with good pricing. Was surprised when I received the
new 16 station expander. To Ray, Salbahra and all contributors, You have done a Good Job !
