Home Assistant - Dual Mode Underfloor Thermostat with floor sensor

About

I have ambient temperature sensors and floor temperature sensors in every room and I want to control the room temperature based on ambient air temperature and also set limit for floor temperature, idividualy for heating and for cooling. This is the first time I used python so please check it before you use it. For the moment I have it set up as 9 thermostats and all is good, but definitly needs more work. At the moment there are no check for min/max values, for example if max is lower than min.

Installation (Manual)

Download this repository as a ZIP (green button, top right) and unzip the archive
Copy /custom_components/dualmode_generic to your <config_dir>/custom_components/ directory
- You will need to create the custom_components folder if it does not exist
- On Hassio the final location will be /config/custom_components/dualmode_generic
- On Hassbian the final location will be /home/homeassistant/.homeassistant/custom_components/dualmode_generic

Configuration

Add the following to your configuration file

climate:
  - platform: dualmode_generic
    name: My Thermostat
    heater: switch.heater
    cooler: switch.fan
    target_sensor: sensor.my_temp_sensor
    reverse_cycle: true
    floor_sensor: sensor.my_floor_temp_sensor
    sensor_mode: smart
    fs_cool_min_temp: 20
    fs_cool_max_temp: 24
    fs_heat_min_temp: 24
    fs_heat_max_temp: 28

The component shares the same configuration variables as the standard generic_thermostat, with three exceptions:

A cooler variable has been added where you can specify the entity_id of your switch for a cooling unit (AC, fan, etc).
If the cooling and heating unit are the same device (e.g. a reverse cycle air conditioner) setting reverse_cycle to true will ensure the device isn't switched off entirely when switching modes
The ac_mode variable has been removed, since it makes no sense for this use case.
floor_sensor variable specifies the entity_id for the floor temperature sensor.
The sensor_mode can change the sensor used for controling the outputs. Values accepted are ambient (default), floor, smart. ambient uses only the air temperature, same as generic thermostat. floor uses only the floor sensor instead of ambient sensor with the aditional limits. smart uses both sensors. Air temperature for target temperature and floor sensors for floor temperature limits. Ambient temperature is valid only when floor temperature is within limits.
The fs_cool_min_temp and fs_cool_max_temp define the limits for cooling mode and fs_heat_min_temp and fs_heat_max_temp define the limits for heating mode.
humidity_sensor entity_id, will be used in the future to stop cooling if value above safety threshold, for the moment it is just passed as an attribute for the climate entity to be used in lovelace card
window_switch entity_id, for the moment it is just passed as an attribute for the climate entity to be used in lovelace card

Refer to the Generic Thermostat documentation for details on the rest of the variables. This component doesn't change their functionality.

Behavior

The thermostat will follow standard mode-based behavior: if set to "cool," the only switch which can be activated is the cooler. This means if the target temperature is higher than the actual temperateure, the heater will not start. Vice versa is also true.
Keepalive logic has been updated to be aware of the mode in current use, so should function as expected.
By default, the component will restore the last state of the thermostat prior to a restart.
While heater/cooler are documented to be switches, they can also be input_booleans if necessary.
