Hi there, everytime I get a powercut all 3 of my nodemcu8266 units keep turning on the outputs. What can I do to stop this?

The outputs are on, although there’s no power??
I’m thinking it turns the relays on when the power is back up
I’m not sure how to prevent this, but maybe it can be done with a capacitor? Quit sure this is an electrical problem and not so much a Blynk thing
I’ve found that the output pins on my ESP01 get pulled high when I restart the board so I run this code in the setup method:
pinMode(pin, OUTPUT);
digitalWrite(pin, LOW);
Thanks all, I’d say that’s all it is that the pin setup must write low at the start. I do this in non Blynk projects but for some reason thought the Blynk standard code covers it. Thanks all I’ll give it a go
