Home Assistant - Gestion de bout en bout du chauffage

This repository contains the files from a post in HACF french forum, adapted to fit my personal setup.

It is the complete implementation of a heating management system for home assistant:

  • Proportional thermostat
  • Heating modes
  • Time schedule
  • Override mode

Please see https://forum.hacf.fr/t/gestion-de-bout-en-bout-du-chauffage/4897 for the original resources

Setup

Helpers

A few helpers are needed :

  • Input numbers:
    • room target temperature
    • Override duration
    • power target for the heater (computed by the proportional thermostat)
  • Input select for selecting the heating mode
  • Timer for the override duration
input_number:
  target:  # The target temperature of the room
    name: Target temperature
    min: 0
    max: 30
    step: 0.2
    mode: slider 
    unit_of_measurement: °C
    icon: mdi:thermometer-check
  power:  # The power value for the heater
    name: heater power
    min: 0
    max: 100
    step: 1
    mode: box
    unit_of_measurement: %
    icon: mdi:lightning-bolt-circle
  override:  # The override duration
    name: Override duration
    min: 0
    max: 12
    step: 1
    mode: slider
    unit_of_measurement: Hours
    icon: mdi:timer-sand
input_select:
  heater_mode:
    name: heater mode
    options:
      - Auto       # Will use the temperature set by the scheduler
      - Dérogation # Override
      - Hors-gel   # Avoid freezing 
      - Stop       # for the Summer 
      - Absent     # Out of the house
    icon: mdi:heat-wave
timer:
  heater_derog:
    name: Heater override duration
    icon: mdi:timer

Schedule

In this setup I use the scheduler and scheduler card from HACS to setup the times and schedules. See here: https://github.com/nielsfaber/scheduler-component

Blueprints

Once you have created the helpers and the scheduler you can create the automations using the blueprints. Create the "Thermostat TPI" first, then the "Pilotage chauffage"

There is an issue in the lovelace card due to ofekashery/vertical-stack-in-card#120
