Heat/Cool Mode

If both heater and cooler entities configured. The thermostat can control heating and cooling and you are able to set min/max low and min/max high temperatures. In this mode you can turn the thermostat to heat only, cooler only and back to heat/cool mode.

Heat/Cool With Fan Mode

If the fan entity is set the thermostat can control the fan mode of the AC. The fan will turn on when the temperature is above the target temperature and the fan_hot_tolerance is not reached. If the temperature is above the target temperature and the fan_hot_tolerance is reached the AC will turn on.

all features ⤴️

Heater Only Mode

If only the heater entity is set the thermostat works only in heater mode.

all features ⤴️

Two Stage (AUX) Heating

Two stage or AUX heating can be enabled by adding the required configuration entities: secondary_heater, secondary heater_timeout. If these are set the feature will enable automatically. Optionally you can set secondary heater_dual_mode to true to turn on the secondary heater together with the primary heater.

How Two Stage Heating Works?

If the timeout ends and the heater was on for the whole time the thermostat switches to the secondary heater. In this case the primary heater (heater) will be turned off. This will be remembered for the day it turned on and in the next heating cycle the secondary heater will turn on automatically. On the next day the primary heater will turn on again the second stage will again only turn on after a timeout. If the third secondary heater_dual_mode is set to true the secondary heater will be turned on together with the primary heater.

Two Stage Heating Example

secondary_heater: switch.study_secondary_heater   # <-- required
secondary_heater_timeout: 00:00:30                 # <-- required
secondary_heater_timeout: true                   # <-- optional

Fan Only Mode

If the fan_mode entity is set to true the thermostat works only in fan mode. The heater entity will be treated as a fan only device.

Fan Only Mode Example

heater: switch.study_heater
fan_mode: true

Fan With Cooler Mode

If the ac_mode is set to true and the fan entity is also set, the heater entity will be treated as a cooler (AC) device with an additional fan device. This will allow not only to use a separate physical fan device but also to turn on the fan mode of an AC using advanced switches. With this setup, you can use the fan mode of your AC in a simpler way.

Fan With Cooler Mode Example

heater: switch.study_heater
ac_mode: true
fan: switch.study_fan

Fan Hot Tolerance

If you also set the fan_hot_tolerance the fan will turn on when the temperature is above the target temperature and the fan_hot_tolerance is not reached. If the temperature is above the target temperature and the fan_hot_tolerance is reached the AC will turn on.

Cooler With Auto Fan Mode Example
heater: switch.study_heater
ac_mode: true
fan: switch.study_fan
fan_hot_tolerance: 0.5

Outside Temperature And Fan Hot Tolerance

If you set the fan_hot_tolerance, outside_sensor and the fan_air_outside the fan will turn on only if the outside temperature is colder than the inside temperature and the fan_hot_tolerance is not reached. If the outside temperature is colder than the inside temperature and the fan_hot_tolerance is reached the AC will turn on.

AC With Fan Switch Support

Some AC systems have independent fan controls to cycle the house air for filtering or humidity control; without using the heating or cooling elements. Central AC systems require the thermostat to turn on both the AC wire ("Y" wire) and the air-handler/fan wire ("G" wire) in order to activate the AC

This feature lets you do just that.

In order to use this feature you need to set the heater entity, the ac_mode, the fan) entity and the fan_on_with_ac to true.

example

heater: switch.study_heater
ac_mode: true
fan: switch.study_fan
fan_on_with_ac: true

Cooler Only Mode

If only the cooler entity is set the thermostat works only in cooling mode.

all features ⤴️

Dry mode

If the dryer entity is set the thermostat can switch to dry mode. The dryer will turn on when the humidity is above the target humidity and the moist_tolerance is not reached. If the humidity is above the target humidity and the moist_tolerance is reached the dryer will stop.

Dry Mode Example with cooler

heater: switch.study_heater
target_sensor: sensor.study_temperature
ac_mode: true
dryer: switch.study_dryer
humidity_sensor: sensor.study_humidity
moist_tolerance: 5
dry_tolerance: 5

Dryer example in dual mode

heater: switch.study_heater
cooler: switch.study_cooler
target_sensor: sensor.study_temperature
dryer: switch.study_dryer
humidity_sensor: sensor.study_humidity
moist_tolerance: 5
dry_tolerance: 5

Heat Pump (one switch heat/cool) mode

This setup allows you to use a single switch for both heating and cooling. To enable this mode you define only a single switch for the heater and set the set youer heat pump's current state (heating or cooling) as for the heat_pump_cooling attribute. This must be an entity id of a sensor that has a state of heating or cooling.

The entity can be an input buulean for manual control or an entity that provided by the heat pump.

heater: switch.study_heat_pump
target_sensor: sensor.study_temperature
heat_pump_cooling: sensor.study_heat_pump_state

Heat Pump Hvac Modes

Openings

The dual_smart_thermostat can turn off heating or cooling if a window or door is opened and turn heating or cooling back on when the door or window is closed to save energy. The openings configuration variable accepts a list of opening entities and opening objects.

Opening entities and objects

An opening entity is a sensor that can be in two states: on or off. If the state is on the opening is considered open, if the state is off the opening is considered closed. The opening object can contain a timeout property that defines the time in seconds after which the opening is considered open even if the state is still on. This is useful if you would want to ignore windows opened only for a short time.

Openings Scope

The openings_scope configuration variable defines the scope of the openings. If set to all or not defined, any open openings will turn off the current hvac device and it will be in the idle state. If set, only devices that operating in the defined HVAC modes will be turned off. For example, if set to heat only the heater will be turned off if any of the openings are open.

Openings Scope Configuration

openings_scope: [heat, cool, heat_cool, fan_only, dry]
openings_scope:
  - heat
  - cool

Openings Configuration

Floor heating temperature control

Maximum floor temperature

The dual_smart_thermostat can turn off if the floor heating reaches the maximum allowed temperature you define in order to protect the floor from overheating and damage. To enable this protection you need to set two variables:

floor_sensor: sensor.floor_temp
max_floor_temp: 28

Minimum floor temperature

The dual_smart_thermostat can turn on if the floor temperature reaches the minimum required temperature you define in order to protect the floor from freezing or to keep it on a comfortable temperature.

Floor Temperature Control Configuration

# Example configuration.yaml entry
climate:
  - platform: dual_smart_thermostat
    name: Study
    unique_id: study

Presets

Currently supported presets are:

To set presets you need to add entries for them in the configuration file like this:

You have 4 options here:

  1. Set the temperature for heat, cool or fan-only mode
  2. Set the target_temp_low and target_temp_high for heat_cool mode. If temperature is not set but target_temp_low and target_temp_high are set, the temperature will be picked based on hvac mode. For heat mode it will be target_temp_low and for cool, fan_only mode it will be target_temp_high
  3. Set the humidity for dry mode
  4. Set all above

Presets Configuration

preset_name:
  temperature: 13
  humidity: 50 # <-- only if dry mode configured
  target_temp_low: 12
  target_temp_high: 14

HVAC Action Reason

State attribute: hvac_action_reason

The dual_smart_thermostat will set the hvac_action attribute to heating, cooling, idle or off based on the current state of the thermostat. The hvac_action attribute is used to indicate the current action of the thermostat. The dual_smart_thermostat will also set the hvac_action_reason attribute based on the current state of the thermostat. The hvac_action_reason attribute is used to indicate the reason for the current action of the thermostat.

HVAC Action Reason values

The hvac_action_reason attribute is grouped by internal and external values. The internal values can be set by the component only and the external values can be set by the user or automations.

HVAC Action Reason Internal values

climate:
  - platform: dual_smart_thermostat
    name: Study
    heater: switch.study_heater
    target_sensor: sensor.study_temperature

    floor_sensor: sensor.floor_temp # <-required
    max_floor_temp: 28 # <-required
    min_floor_temp: 20 # <-required

DUAL Heat-Cool Mode Example

This mode is used when you want (and can) control both the heater and the cooler. In this mode the target_temp_low and target_temp_high must be set. In this mode you can switch between heating and cooling by setting the hvac_mode to heat or cool or heat_cool.

climate:
  - platform: dual_smart_thermostat
    name: Study
    heater: switch.study_heater # <-required
    cooler: switch.study_cooler # <-required
    target_sensor: sensor.study_temperature
    heat_cool_mode: true # <-required
    initial_hvac_mode: "heat_cool"

OPENINGS Example

climate:
  - platform: dual_smart_thermostat
    name: Study
    heater: switch.study_heater
    cooler: switch.study_cooler
    target_sensor: sensor.study_temperature
    openings: # <-required
      - binary_sensor.window1
      - binary_sensor.window2
      - entity_id: binary_sensor.window3
        timeout: 00:00:30 # <-optional

Tolerances

The dual_smart_thermostat has two tolerance variables: cold_tolerance and hot_tolerance. These variables are used to prevent the heater or cooler from switching on and off too frequently. For example, if the target temperature is 25 and the tolerance is 0.5 the heater will start when the sensor equals or goes below 24.5. The heater will stop when the sensor equals or goes above 25.5. This prevents the heater from switching on and off too frequently when the temperature is close to the target temperature.

If the thermostat is set to heat_cool mode the tolerance will work in the same way for both the heater and the cooler.

climate:
  - platform: dual_smart_thermostat
    name: Study
    heater: switch.study_heater
    cooler: switch.study_cooler
    target_sensor: sensor.study_temperature
    cold_tolerance: 0.3
    hot_tolerance: 0
