Hi everybody,
while at the time of writing this is not critical, for the future i’d like to use the attached cooling fan on my RPi 4 (HASS installation in a DIN enclosure in the breaker box) to come on as required. I have created a little board which can read out PWM signals through a GPIO pin and control the fan accordingly, this was tested under Raspberry OS on this machine and it worked without problems. Here’s the circuit layout:
I then installed both the pi_gpio and pi_gpio_pwm integrations through HACS and no errors are reported by the system.
As per the installation manual provided, I added the following to configuration.yaml:
fan:
- platform: rpi_gpio_pwm
fans:
- name: RPI Cooling Fan
pin: 4
unique_id: procfan
The configuration test shows no errors, still there’s nothin showing up, neither on the dashboard nor in the entities list. Any ideas?
