Multi fan PID controller

ESPHome
1

hi,

I have built PID PWM fan controller on ESP32 and I have small issue:

  • there are 2 fans, each one is 4pin so each can be controlled separately, but
  • I would like to group them: the same PWM signal to be send to both GPIOs (but I don’t want to connect them to the same GPIO electrically)

now question: how to set the same output (PWM) on 2 different outputs?
PID controller sends value to fan1:

climate:
  - platform: pid
...
    cool_output: ch1_pwm

fan1 is here:

fan:
  - platform: speed
    output: ch1_pwm
    name: "$hostname Fan1"

and output is here:

output:
  - platform: ledc
    pin: $ch1_pwm_gpio  
    id: ch1_pwm

there is another fan:

fan:
  - platform: speed
    output: ch2_pwm
    name: "$hostname Fan2"

and another output:

output:
  - platform: ledc
    pin: $ch2_pwm_gpio  
    id: ch2_pwm

where to put the control of fan2?
climate does not allow 2 outputs
fan1? output1?

I am stupid here

thx.
