Ha thermostat automatization with chinese temp sensor (zigbee 4$)

[marek9336]

I was frustrated that I couldn't find automation for the heat pump, so I made my own. I recommend adding this to your proposed automation.

I used yaml to add a virtual thermostat that uses a cheap sensor from aliexpress and automated my LG heat pump.

First, I added a virtual thermostat to configuration.yaml, which controls the temperature according to the sensor from aliexpress:

climate:
 - platform: generic_thermostat
   name: Virtual Thermostat
   heater: switch.dummy_switch
   target_sensor: sensor.temperature_humidity_sensor_temperature # Temperature sensor from aliexpress
   min_temp: 15
   max_temp: 25
   initial_hvac_mode: "off"
   precision: 0.1 # The accuracy of the thermostat

I also created two automations, one that increases the temperature, the other that decreases the temperature of the pump.

Temp + :

alias: Termostat +1°C

  - platform: time_pattern
    enabled: true
    minutes: /30

  - condition: template
    value_template: >-
      {{ (state_attr('climate.virtual_thermostat', 'temperature') | float) -
      (state_attr('climate.virtual_thermostat', 'current_temperature') | float)
      | abs > 0.2 }}
    enabled: true

    data_template:

      temperature: >
        {% set target_temp = state_attr('climate.tepelne_cerpadlo',
        'temperature') | float %} {% set current_temp =
        state_attr('climate.virtual_thermostat', 'current_temperature') | float
        %} {% if current_temp > target_temp + 0.2 %}
          {{ target_temp - 1 }}
        {% elif current_temp < target_temp - 0.2 %}
          {{ target_temp + 1 }}
        {% else %}
          {{ target_temp }}
        {% endif %}

        state_attr('climate.virtual_thermostat', 'current_temperature') | float
        %} {% if current_temp < target_temp + 0.2 %}
          {{ target_temp - 1 }}
        {% elif current_temp > target_temp - 0.2 %}
          {{ target_temp + 1 }}
        {% else %}
          {{ target_temp }}
        {% endif %}
mode: single

In addition, temperature + turns on the pump, if I turned off the pump manually, in the future I want to automate the pump shutdown when it heats to less than 25°, because then it heats almost empty. If someone figured out how to improve this script including turning off the pump, I would be happy if they improved it into one automation including both automations.
I know, that my scripts are not perfect, but it works and I'll be happy if someone fixes it, thanks it was a lot of experiments and I'm too lazy to fix it when it works :-)

I wish you a nice day and successful automation!

The goal of home-assistant is to use available entities together to create automations.
Integration just provide entities for a specific device, should not provide any automation.
You correctly you create your automation using entities provided by multiple integration, I'm not understanding what you are asking for
