Yes it does have, but as i wrote, it dries out too fast. Tried my neighbor’s sensor too, (different type), and also the same.
I think it would be really useful for many of us out there, to have the same (or similar) delay options regardless of the methods used (Zimmerman or local sensor).
All that would need to be done is to just add an option with how many hours of delay would be needed after the rain has beed detected. To cancel it (when the event has happened), one would just have to set this value to zero and that’all.
