Generic Hygrostat for Home Assistant

Due to the fact that humidity levels are different during the summer and winter, a static humidity level switching the fan is on/off is not possible. This binary_sensor detects high rises in humidity and switches on. And switches off when the humidity is back to normal.

Inspired by: https://www.domoticz.com/wiki/Humidity_control

Setup

In your configuration.yaml you'll need:

binary_sensor:
- platform: generic_hygrostat
  name: Bathroom Hygrostat
  sensor: sensor.bathroom_climate_humidityy # Source humidity sensor
  delta_trigger: 3 # Optional humidity swing to detect. Default = 3
  target_offset: 3 # Optional dehumidification target offset. Default = 3
  max_on_time: 7200 # Optional safety max on time in seconds. Default = 7200 seconds
  sample_interval: 300 # Optional time between taking humidity samples in seconds, default 300 seconds
  min_humidity: 30 # Optional minimum humidity to enable dehumidification. Default = 0

It will create a binary sensor called binary_sensor.bathroom_hygrostat. Next, add some automations to switch your fan:

automation:
- alias: Bathroom Hygrostat On
  trigger:
    platform: state
    entity_id: binary_sensor.bathroom_hygrostat
    to: 'on'
  action:
    - service: switch.turn_on
      entity_id: switch.fan

- alias: Bathroom Hygrostat Off
  trigger:
    platform: state
    entity_id: binary_sensor.bathroom_hygrostat
    to: 'off'
  action:
    - service: switch.turn_off
      entity_id: switch.fan
