Switch Fan ON/OFF - How To?

Configuration
1

I have a fan connected to pin 4&6. I need to switch it on/off with a button on dashboard. Is it possible?

2

To pin 4&6 of what? What is the entity type?

3

GPIO of Raspberry Pi 4 > 5v+gnd pin

Direct support by HA of GPIO’s has been discontinued for a while. I use MQTT. On RPi side you have to setup MQTT on RPi

I have found this: Can help?

6

I never succeeded to make it work, hence MQTT. Maybe you will be luckier.

The library is for driving GPIO’s. I’m not aware of any mean to switch off the 5V output. You should set up some circuitry driven by a GPIO to achieve your goal,
