Hi, i really liked the work made by Sam04, so heavly inspired by his work i created my verion of this temperature controlled fan blueprint.
Fan turns on if temperature inside is greater than the threshold value considering outside temperature (during winter). I removed the occupancy entity so the fan is dependent only from the temperature.
I use it to automatically turn on and off the cpu fan based on cpu temperature sensor, so it doesn't make useless noise.
Make sure to set the temperature device class for sensor and fan for entity even if you use a switch like me. (you can use platform template for both)
Sensors example:
Fan entity must be included in fan domain, if you have a switch, you shoud use a template.
fan:
- platform: template
fans:
cpu_rack_fan:
friendly_name: "CPU Rack fan"
value_template: "{{ 'on' if is_state('switch.fan_rack', 'on') else 'off' }}"
turn_on:
service: switch.turn_on
data:
entity_id: switch.fan_rack
turn_off:
service: switch.turn_off
data:
entity_id: switch.fan_rackTemperature sensor -> template
sensor:
- platform: command_line
name: CPU Temperature
command: "cat /sys/class/hwmon/hwmon0/temp1_input"
unit_of_measurement: "°C"
value_template: '{{ value | multiply(0.001) | round(1) }}'
- platform: template
sensors:
cpu_sensor_temperature:
friendly_name: "CPU Temperature Sensor"
unit_of_measurement: "°C"
value_template: "{{ states('sensor.cpu_temperature') }}"
device_class: temperature
