Basement Fan to attic configuration

Configuration
1

Hello all,

I have a Fan in the basement to bring cold air to the attic. Here are the hardware components I’m using to make this possible, but need some automation adjustments.

  • TerraBloom 6 Inch Fan
  • Aeotec aërQ Temperature and Humidity Sensor
  • Aoycocr Alexa Smart Plugs
if:
  - type: is_temperature
    condition: device
    device_id: 0be1d2ecca17f0137c45e3d6fa0bfda1
    entity_id: sensor.sensor_air_temperature
    domain: sensor
    above: 78
then:
  - type: turn_on
    device_id: 6e29b20657606f8cdfba5df0c114a602
    entity_id: switch.smart_socket_socket_1
    domain: switch
else:
  - type: turn_off
    device_id: 6e29b20657606f8cdfba5df0c114a602
    entity_id: switch.smart_socket_socket_1
    domain: switch

So, I would like the Fan to do the following:

If the basement temperature is 10 degrees cooler than the attic and the attic is over 78, then turn it on for 10 minutes, and check again. I would also like to add some way to check presence in the room first but don’t have any sensor yet. Since I have computers in the attic I guess I could do something like, if the computer is been used then trigger…

Any recommendations here?

I’ve done a bunch of automations like that, and have found simpler paths.

First, setup a Generic Thermostat component. Configure it for cool mode

Get this working so your fan comes on when the attic is over the setpoint in the thermostat.

Next, you only want the thermostat in cool mode if the difference in temperature between attic and basement is greater than 10 degrees. Setup a binary sensor template that is true when it is greater than 10.

Lastly create two automations. One that runs when that binary sensor is True and one that runs when it is false. And within turn the thermostat to off or cool mode.

  action:
    - service: climate.set_hvac_mode
      target:
        entity_id: climate.woodstove
      data:
        hvac_mode: cool

When you get presence detection you can use that to control the setpoint and/or in the automations to enable or disable cooling

I have a terrabloom inline fan as well, and Id love to be able to control it in HA. Is there config already made to do so with this fan? I have a remote for it already but prefer HA

What kind of control? All I can do is On/Off. I made sure I was using the “right” speed and that was it.
