My instance of Opensprinkler on ESP8266 work sins two mount now whit out any significant problems. I can complain only speed but to be honest this is not big issue. However just after initial compilations I’ve observed strange behavior.
After power up device always end-up in WiFi Manager mode. Entering password and WiFi Name and soft reset switched device in operational mode. Hard reset and again WiFi Manager mode. After some googling I’ve found solution. Adding below two lines in to “bool EtherCardW5100::WiFiconnect()” in file EtherCard5100.cpp (after DEBUG_PRINTLN(“Wait WIFI…”);) totally solved the issue.
Hope this will be usable for anyone.
