The problem comes when I want to switch the relay from the Blynk app. Than the ESP8266 disconnects (nearly immediately, or after few seconds). I tried a different DC motor (not a water pump) and it worked fine. I also tried to switch the pump without using EPS8266, that worked as well (so the code should be ok). I think this has something to do with the current draw caused by the water pump.
