Hi
I am making a weather station. I want to know about Pulse Counter. Can I use GPIO1-4. Or do I have to use free GPIOs onboard.

Pulse Counter Sensor
ESPHome Weather Station

these can be used:
1-wire GPIO for DS18B20/DHT11/DHT21/LED strip -1: GPIO5
1-wire GPIO for DS18B20/DHT11/DHT21/LED strip -2: GPIO14
1-wire GPIO for DS18B20/DHT11/DHT21/LED strip -3: GPIO13
1-wire GPIO for DS18B20/DHT11/DHT21/LED strip -4: GPIO33

or some free GPIOs on PCB hole (ONLY use for INPUT):
I36
I37
I38
I39
I34
