I learned that I have to reinstall the firmware again. Unfortunately I get some errors if I try to compile the files as given in the github repository. Maybe this is due to the fact that the OSBeeWiFi Firmware 1.0.0 was released more than 2 years ago? Is it possible to get access to the complied firmware named mainArdunio.cpp.bin or is it available on the web?
I need to upload the firmware in Arduino via USB as OTA update is not working anymore.
Help needed as my sprinkler systems depends on OSBeeWiFi.
