The use of the ESP8266 in the world of IoT

#94538 I’m running NodeMCU 8266 with the Cloud4rpi MQTT web service. I have a Cloud4rpi switch control that when set to True switches on an external LED on GPIO12.

BUT I want this to switch a relay too, and True on GPIO12 is 0V not 3.3 (measured on a voltmeter). This means the relay switches on when the switch is set to False, and off when it’s True - so the opposite of the LED.

Any ideas how to fix this so the LED is On and the relay is powered at the same time?
