An awesome thermostat with preset mode management + windows opening management + activity sensor management

Component developed by using the amazing development template [blueprint][blueprint].

This custom component for Home Assistant is an upgrade of my first component "simple thermostat" with addition of trully awesome features.

Why another thermostat implementation ?

For my personnal usage, I needed to add a couple of features and also to update the behavior that I implemented in my previous component "Simple thremostat". This new component "Awesome thermosts" now manage the awesome use cases :

• Explicitely define the temperature for presets mode in config file.
• Unset the preset mode when the temperature is manually defined on a thermostat.
• Turn off/on a thermostat when a door or windows is opened/closed.
• Set a temperature when an activity is detected in a room, and another one after no activity has been detected for a defined time.

That's awesome ! How Can I enjoy this awesome thermostat ?

HACS installation

1. Install HACS. That way you get updates automatically.
2. Add this Github repository as custom repository in HACS settings.
3. search and install "Awesome Thermostat" in HACS and click install.
4. Modify your configuration.yaml as explain below.
5. Restart Home Assistant.

Manual installation

1. Using the tool of choice open the directory (folder) for your HA configuration (where you find configuration.yaml).
2. If you do not have a custom_components directory (folder) there, you need to create it.
3. In the custom_components directory (folder) create a new folder called awesome_thermostat.
4. Download all the files from the custom_components/awesome_thermostat/ directory (folder) in this repository.
5. Place the files you downloaded in the new directory (folder) you created.
6. Modify your configuration.yaml as explain below
7. Restart Home Assistant

Minimum requirements

• This implementstion can override or superseed the core generic thermostat

Configuration

In the following examples we are assuming that you know how to configure a generic thermostat (if not please have a look at : https://www.home-assistant.io/integrations/generic_thermostat/ ) and we will just highlight the differences in the configuration to apply.

Minimal configuration update

The minimal configuration for a generic thermostat is the following :

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

If you want to switch to an awesome thermostat, your new configuration will be :

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

Congrats ! You just migrate to an awesome thermostat behaving exactly like the generic one !

What !? But where are the awesome features? The preset modes for example ?

Ok, let's start the real fun. Concerning the preset modes, you first have to know that, as defined in the core development documentation (https://developers.home-assistant.io/docs/core/entity/climate/), the preset mode handled are the following :

• ECO : Device is running an energy-saving mode
• AWAY : Device is in away mode
• BOOST : Device turn all valve full up
• COMFORT : Device is in comfort mode
• HOME : Device is in home mode
• SLEEP : Device is prepared for sleep
• ACTIVITY : Device is reacting to activity (e.g. movement sensors)

As it was implemented in generic thermostat, I extended the management of the temperatures for each mode by configuration with te following keys : eco_temp, away_temp, boost_temp, comfort_temp, home_temp, sleep_temp An exception was made for activity as for this specific mode we need to set 2 temperatures. Just remember that setting activity_temp won't work. So imagine that you want to set temperature for each of the classic preset mode, your new configuration file will be :

climate:
  - platform: awesome_thermostat
    name: Study
    heater: switch.study_heater
    target_sensor: sensor.study_temperature
    eco_temp: 18.5
    away_temp: 16
    boost_temp: 23
    comfort_temp: 21.5
    sleep_temp: 20

In this example you can see that I didn't set activity_temp BECAUSE IT DOESN'T WORK for this preset mode. Also I didn't set home_temp because I don't need it. The result of this configuration is that I created a thermostat on which I can choose the following modes : Eco, Away, Boost, Comfort, Sleep and None.

'None' is always added in the list of modes, as it is a way to not use the presets modes but a manual temperature instead. !!! IMPORTANT !!! The contrary of the previous sentence is also true : IF A PRESET MODE IS SET, IT WILL BE CHANGE TO NONE IF YOU MANUALLY CHANGE THE TEMPERATURE.

Awesome ! And What about the doors/windows turning on/off the thermostats ?

Good question ! The use case is the following : every morning I open the windows of the rooms to renew the air and of course the thermostat have to be stopped. And when I close the windows, the thermostat must be turned on. As I have sensor on all of my doors and windows, I decided to use them to automatize this action. The only thing that we need to declare is the windows sensor, with the config key window_sensor :

climate:
  - platform: awesome_thermostat
    name: Study
    heater: switch.study_heater
    target_sensor: sensor.study_temperature
    eco_temp: 18.5
    away_temp: 16
    boost_temp: 23
    comfort_temp: 21.5
    sleep_temp: 20
    window_sensor: binary_sensor.study_windows

And that's it ! your thermostat will turn off when the windows is open and be turned back on when it's closed. Note 1 : this implementation is based on 'normal' door/windows behavior, that'smean it considers it's closed when the state is 'off' and open when the state is 'on' Note 2 : If you want to use several door/windows sensors to automatize your thermostat, just create a group with the regular behavior (https://www.home-assistant.io/integrations/binary_sensor.group/).

Configure the activity mode

We will now see how to configure the new Activity mode. For this mode I freely inspired myself from a blueprint shared by @ChrisInUK (https://community.home-assistant.io/t/motion-controlled-room-eco-heating/291322) and I gratefully thank him for his job. What we need:

• a motion sensor. The key in configurationfile is "motion_sensor".
• a target "motion" mode. We will used the same temperature than this mode when an activity is detected. The key in configurationfile is "motion_mode".
• a target "no motion" mode. We will used the same temperature than this mode when no activity is detected. The key in configurationfile is "no_motion_mode".
• a "motion delay" duration defining how many time we leave the temperature like in "motion" mode after the last motion is detected. The key in configurationfile is "motion_delay".

So imagine we want to have the following behavior :

• we have room with a thermostat set in activity mode, the "motion" mode chosen is comfort (21.5C), the "no motion" mode chosen is Eco (18.5 C) and the motion delay is 5 min.
• the room is empty for a while (no activity detected), the temperature of this room is 18.5 C
• somebody enters into the room, an activity is detected the temperature is set to 21.5 C
• the person leaves the room, after 5 min the temperature is set back to 18.5 C

The configuration we have to set is the following :

climate:
  - platform: awesome_thermostat
    name: Study
    heater: switch.study_heater
    target_sensor: sensor.study_temperature
    eco_temp: 18.5
    away_temp: 16
    boost_temp: 23
    comfort_temp: 21.5
    sleep_temp: 20
    motion_sensor: input_boolean.study_motion_sensor
    motion_mode: comfort
    no_motion_mode: eco
    motion_delay:
      minutes: 5

Be aware that as for the others preset modes, Activity will only be proposed if it's correctly configure. In other words, the 4 configurayion keys have to be set if you want to see Activity in home assistant Interface

Even Better with Scheduler Component !

In order to enjoy the full power of awesome thermostat, I invite you to use it with https://github.com/nielsfaber/scheduler-component Indeed, the scheduler component porpose a management of the climate base on the preset modes. This feature has limited interest with the generic thermostat but it becomes highly powerfull with Awesome thermostat :

Starting here, I assume you have installed Awesome Thermostat and Scheduler Component.

In Scheduler, add a schedule :

Choose "climate" group, choose one (or multiple) entity/ies, select "MAKE SCHEME" and click next : (it is possible to choose "SET PRESET", but I prefer to use "MAKE SCHEME")

Set your mode scheme and save :

In this example I set ECO mode during the night and the day when nobody's at home BOOST in the morning and COMFORT in the evening.

I hope this example helps you, don't hesitate to give me your feedbacks !
