Has anyone had any success with the ESP8266 development (https://github.com/SchreiverJ/SmartThingsESP8266) by smartthings? When I try to create a new smartapp from code provided I get an error message which begins "Validation Error(s) occurred during save(): - Field error in object ‘physicalgraph.app.SmartAppVersion’ on field ‘iconUrl’: rejected value [null]; codes "
I have tried to find the problem without success.
