I recently purchased the OpenFAN Micro from OpenFAN Micro – Karanovic Research

Working through the documentation, I setup a RESTful Command integration and I wanted to share my initial setup. Testing soon to come.

My mission: Control dual Noctua NF-S12A PWM 4-Pin fans for my server rack via variable speed controls based on internal temperatures.

OpenFAN Micro API Documentation: Web API - Karanovic Research

rest_command:
  set_fan_pwm:
    url: "http://192.168.0.150/api/v0/fan/0/set?value={{ pwm_value }}"
    method: get

sensor:
  - platform: rest
    name: "OpenFAN Micro RPM"
    resource: "http://192.168.0.150/api/v0/fan/status"
    value_template: "{{ value_json.rpm }}"
    unit_of_measurement: "RPM"

  - platform: rest
    name: "OpenFAN Micro PWM"
    resource: "http://192.168.0.150/api/v0/fan/status"
    value_template: "{{ value_json.pwm_percent }}"
    unit_of_measurement: "%"

fan:
  - platform: template
    fans:
      openfan_micro:
        friendly_name: "OpenFAN Micro"
        value_template: "{{ states('sensor.openfan_micro_rpm')|int(0) > 0 }}"
        percentage_template: "{{ states('sensor.openfan_micro_pwm')|int(0) }}"
        turn_on:
          sequence:
            - action: rest_command.set_fan_pwm
              data:
                pwm_value: "50" # Default to 50% when turning on
        turn_off:
          - action: rest_command.set_fan_pwm
            data:
              pwm_value: "0"
        set_percentage:
          - action: rest_command.set_fan_pwm
            data_template:
              pwm_value: "{{ percentage | int }}"

One thing I failed to add was unique_id to the sensors and fan above their names.
