Ok, thank you for the answer.
salbahra, you said that I can connect directly to a computer using a cross-over cable. How do you do that ? When I try it my connection is said “limited or inexistant”
And the opensprinkler has no ip I can connect to (indicated 0.0.0.0)
And Ray, excuse me for the questions/remarks that you took so bad. I was just saying that sometimes you don’t have internet, or sometimes it is down, and someone would like to still be able to use the UI at that time.
And sometimes, it could be convenient to access the pensprinkler without a router.
But no problem, I understood your answer and your jokes about the valves.
