US wire based thermostat component

[jarrettv]

Describe the problem you have/What new integration you would like The current configuration for thermostat is very flexible but also complex. I'd like to see something that works more in line with a typical off the shelf thermostat automatically. For example, for my heat pump with aux heat, the config would be:

climate:
  - platform: thermostat_us
    id: esp_thermostat
    name: ${node_friendly_name}
    sensor: bme280_temp
    mode_input: rotary_button
    fan_mode_input: side_button
    raise_lower_input: rotary_encoder
    default_target_low: 67°F
    default_target_high: 72°F
    aux_mode: eco
    wires:
      - fan: triac_green_wire
      - compressor: triac_yellow_wire
      - reversing_valve: triac_orange_wire
      - aux_heat: triac_white_wire
    on_change:
      then:
        - component.update: oled

Please describe your use case for this integration and alternatives you've tried: I've tried the existing thermostat and yes it will satisfy my use case, however it is more complicated than expected.

Additional context By default it should support fan: ON/AUTO, mode: OFF/COOL/HEAT/EM HEAT/AUTO and should have all the logic for how a typical thermostat would work. For example, I think most thermostats call for aux heat if you have +2 degree temperature delta. You can override default behavior with a different aux_mode.

We also need built in methods for toggle of the modes.

For example:

`ClimateCall::toggle_mode` cycle ['auto', 'off', 'heat', 'cool', 'em heat']
`ClimateCall::toggle_fan_mode` cycle ['auto', 'on' ]
`ClimateCall::toggle_em_heat_mode` cycle ['comfort', 'normal', 'eco', 'saver']
`ClimateCall::raise_temp` 
`ClimateCall:lower_temp`

I'd also like to see some of these compressor and other settings included and defaulted in the thermostat logic:

Potential rule additions, + likely need to include, - too advanced for now, ? not sure

+Auto Heat/Cool Minimum Delta, 5F 2.8C +Heat Dissipation Time 15s? +Cool Dissipation Time 15s? +Heat Diff Temp = 0.5F 0.3C +Cool Diff Temp = 0.5F 0.3C +Heat Min On Time = 300s -AC Overcool Max = Humidity -Temperature Correction -Humidity Correction +Compressor Minimum Cycle Off Time 300s +Compressor Minimum On Time 300s -Compressor Minimum Outdoor Temperature: depends on region and equipment 22F or -2C -Compressor Stage 2 Temperature Delta -Compressor Reverse Staging -Compressor Stage 1 Max Runtime

+Aux Heat Max Outdoor Temperature = default none? +Aux Heat Minimum On Time = yuk 300s ?Compressor to Aux Temperature Delta = auto ?Compressor to Aux Runtime = auto -Aux Stage 2 Temperature Delta -Aux Reverse Staging -Aux Stage 1 Max Runtime

I've been kicking this idea around a lot in my head and, rather than making a separate component (which will likely bring about more confusion), I think it would make more sense to extend the functionality of the existing thermostat component. I had an idea that I think would work well...

We could add a wires (or honestly I think gpios would make more sense as it relates to ESPHome) section to the existing component's configuration. So, for example, you could have:

# Example dual-point configuration entry
climate:
  - platform: thermostat
    name: "Thermostat Climate Controller"
    sensor: some_temperature_sensor
    default_target_temperature_low: 20 °C
    default_target_temperature_high: 22 °C
    cool_action:
      - script.execute: some_cool_script
    heat_action:
      - script.execute: some_heat_script
    idle_action:
      - script.execute: some_off_script
    gpios:
      - fan: triac_green_wire
      - compressor: triac_yellow_wire
      - reversing_valve: triac_orange_wire
      - aux_heat: triac_white_wire

The other options you're talking about adding would be pretty simple to bring into the configuration, too. They'd just end up as additional configuration options along side of those that already exist.

I like it. I've spent some quality time with the thermostat component and it makes sense to build it into existing one. I like gpios or maybe even switches since that is component being hooked up (similar to sensor for temp).

I think the first couple safety threshold configs should be:

• Compressor Minimum Cycle Off Time 300s
• Compressor Minimum On Time 300s
