Hello, In my configuration BTT pi 1.2v, I’m receiving the error “Unknown pin chip name host’.”

I configured in printer.cfg serial: /tmp/klipper_host_mcu and added the following also in printer.cfg:

[temperature_fan raspberry_pi]
pin: host:gpio211
kick_start_time: 0.8
#shutdown_speed: 0
off_below: 0.1
max_power: 1.0
#fan_speed: 0.6
sensor_type: temperature_host
control: pid
min_temp: 0
max_temp: 85
#max_delta: 5.0
pid_kp: 1.0
pid_ki: 0.5
pid_kd: 2.0
min_speed: 0.1
max_speed: 0.6
target_temp: 38

Next time please open a separate thread and do not hijack others.
You klippy.log is essential for helping!

Did you declare the following properly in your printer.cfg:

[mcu host]

If not or if unsure upload your current klippy.log!

Thank you so much

[mcu host]

and no only [mcu]

this fan max Voltage is only 5v??

[mcu]

is for the printer board and

[mcu host]

would be for your RasPi/SBC (where it seems you have the fan connected to).
You can name it differently as well.
The RasPi provides 5 v only.

Before messing around please upload your current klippy.log or at least your printer.cfg.
