Programmable thermostat that let you have a smart thermostat on budget.

PROGRAMMABLE THERMOSTAT

This component is a revision of the official Home Assistant component 'Generic Thermostat' in order to have possibility to have target temperature variable according to a sensor state value.

HOW TO INSTALL

Just copy paste the content of the climate.programmable_thermostat/custom_components folder in your config/custom_components directory.

As example you will get the '.py' file in the following path: /config/custom_components/programmable_thermostat/climate.py.

Note: you can install through HACS.

EXAMPLE OF SETUP

Here below the example of setup of sensor and parameters to configure.

climate:
  - platform: programmable_thermostat
    name: room
    heater: switch.riscaldamento
    cooler: switch.condizionamento
    actual_temp_sensor: sensor.target_temperature
    min_temp: 10
    max_temp: 30
    target_temp_sensor: sensor.program_temperature
    tolerance: 0.3
    

Field	Value	Necessity	Comments
platform	programmable_thermostat	Required
name	Programmable Thermostat	Optional
heater		Conditional	Switch that will activate/deactivate the heating system. At least one between heater and cooler has to be defined.
cooler		Conditional	Switch that will activate/deactivate the cooling system. At least one between heater and cooler has to be defined.
actual_temp_sensor		Required	Sensor of actual room temperature.
min_temp	5	Optional	Minimum temperature manually selectable.
max_temp	40	Optional	Maximum temperature manually selectable.
target_temp_sensor		Required	Sensor that rapresent the desired temperature for the room. Suggestion: use my file_restore compontent or somthing similar.
tolerance	0.5	Optional	Tolerance for turn on and off the switches mode.
initial_hvac_mode	heat, cool, off	Optional	If not set, components will restore old state after restart. I suggest to not use it.

SPECIFICITIES

TARGET TEMPERATURE SENSOR

target_temp_sensor is the Home Assistant entity_id of a sensor which state change accrodingly a specified temperature profile. This temperature profile should described the desired temperature for the room each day/hour. target_temp_sensor must have a temperature value (number with or without decimal) as state.

Suggestion: use my file_restore custom components.

ADDITIONAL INFO

Programmed temperature will change accordingly to the one set by the target_temp_sensor, this will not happen if the mode is set to heat_cool. (it is the old manual mode that has been removed from the climate component) In heat and cool modes you can still change manually the temperature for the room, but in this case the target temperature will be set, again, to the one of target_temp_sensor at its first change.

heat and cool modes rapresent the automatic mode.

After a restart of Home Assistant, room temperature e planned room temperature will match till actual_temp_sensor will return a temperature value. This is done to avoid possible issues with Homekit support with temperature sensor that need some time to sync with Home Assistant.

NOTE

This component has been developed for the bigger project of building a smart thermostat using Home Assistant and way cheeper then the commercial ones. You can find more info on that here
