Thanks for the reply,
The first post is from @ja.charer , using https://github.com/dancol90/ESP8266Ping
And i have said https://github.com/dancol90/ESP8266Ping in my post in page 8 first message, i use it too.
it will be glad, if you willing to read my reply.
but it seem you’re to busy.
i’am sory, i’am not touching OpenSprinkler.h, because you said only change pin.h
and i already upload my pin.h, you can see, i only do what you have said.
Never mind, i already give up.
have a nice day.
i have modified the pin button to using gpio in https://github.com/OpenSprinkler/OpenSprinkler-Firmware .
so i will continue to play with it.
