Where does the FAN operation set up in SETUP?


I connected the power control-4-channel ssr-RJ45 cable, and I connected the FAN to GPIO26 and set it on which menu in SETUP? For example, operate when the temperature is above 30 degrees and humidity is above 80 percent

The 3.3 volt signal from the GPIO switches the relay on and off. This can be set up on the Outputs page with the GPIO On/Off Output. Your fan will plug into the outlet controlled by the relay. Then you can control the fan from the Output in Mycodo.
